## Usage ### `URLExtractor` The `URLExtractor` wraps a PSR-18 `ClientInterface` to extract and follow shortened URLs to their original location. ```php // @see https://github.com/chillerlan/php-httpinterface $options = new HTTPOptions; $options->user_agent = 'my cool user agent 1.0'; $options->ssl_verifypeer = false; $options->curl_options = [ CURLOPT_FOLLOWLOCATION => false, CURLOPT_MAXREDIRS => 25, ]; $httpClient = new CurlClient($responseFactory, $options, $logger); $urlExtractor = new URLExtractor($httpClient, $responseFactory); $request = $factory->createRequest('GET', 'https://t.co/ZSS6nVOcVp'); $urlExtractor->sendRequest($request); // -> response from the final location // you can retrieve an array with all followed locations afterwards $responses = $urlExtractor->getResponses(); // -> ResponseInterface[] // if you just want the URL of the final location, you can use the extract method: $url = $urlExtractor->extract('https://t.co/ZSS6nVOcVp'); // -> https://api.guildwars2.com/v2/build ``` ### `EchoClient` The `EchoClient` returns a JSON representation the original message: ```php $echoClient = new EchoClient($responseFactory); $request = $requestFactory->createRequest('GET', 'https://example.com?whatever=value'); $response = $echoClient->sendRequest($request); $json = json_decode($response->getBody()->getContents()); ``` Which yields an object similar to the following ```json { "headers": { "Host": "example.com" }, "request": { "url": "https://example.com?whatever=value", "params": { "whatever": "value" }, "method": "GET", "target": "/", "http": "1.1" }, "body": "" } ``` ### `LoggingClient` The `LoggingClient` wraps a `ClientInterface` and outputs the HTTP messages in a readable way through a `LoggerInterface` (do NOT use in production!). ```php $loggingClient = new LoggingClient($httpClient, $logger); $loggingClient->sendRequest($request); // -> log to output given via logger ``` The output looks similar to the following (using [monolog](https://github.com/Seldaek/monolog)): ``` [2024-03-15 22:10:41][debug] LoggingClientTest: ----HTTP-REQUEST---- GET /get HTTP/1.1 Host: httpbin.org [2024-03-15 22:10:41][debug] LoggingClientTest: ----HTTP-RESPONSE--- HTTP/1.1 200 OK Date: Fri, 15 Mar 2024 21:10:40 GMT Content-Type: application/json Content-Length: 294 Connection: keep-alive Server: gunicorn/19.9.0 Access-Control-Allow-Origin: * Access-Control-Allow-Credentials: true { "args": {}, "headers": { "Host": "httpbin.org", "User-Agent": "chillerlanPHPUnitHttp/1.0.0 +https://github.com/chillerlan/phpunit-http", "X-Amzn-Trace-Id": "Root=1-65f4b950-1f87b9e37182673438091aea" }, "origin": "93.236.207.163", "url": "https://httpbin.org/get" } ``` ## API The following classes contain static methods for use with PSR-7 http message objects. ### `HeaderUtil` | method | return | info | |-------------------------------------|----------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `normalize(array $headers)` | `array` | Normalizes an array of header lines to format `["Name" => "Value (, Value2, Value3, ...)", ...]` An exception is being made for `Set-Cookie`, which holds an array of values for each cookie. For multiple cookies with the same name, only the last value will be kept. | | `trimValues(array $values)` | `array` | Trims whitespace from the header values | | `normalizeHeaderName(string $name)` | `string` | Normalizes a header name, e.g. "conTENT- lenGTh" -> "Content-Length" | ### `QueryUtil` | method | return | info | |--------------------------------------------------------------------------------------------------|-----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `cleanParams(iterable $params, int $bool_cast = null, bool $remove_empty = true)` | `array` | Cleans/normalizes an array of query parameters, booleans will be converted according to the given `$bool_cast` constant. By default, booleans will be left as-is (`Query::BOOLEANS_AS_BOOL`) and may result in empty values. If `$remove_empty` is set to true, empty non-boolean and null values will be removed from the array. The `Query` class provides the following constants for `$bool_cast`:
`BOOLEANS_AS_BOOL`: unchanged boolean value (default)
`BOOLEANS_AS_INT`: integer values 0 or 1
`BOOLEANS_AS_STRING`: "true"/"false" strings
`BOOLEANS_AS_INT_STRING`: "0"/"1" strings | | `build(array $params, int $encoding = null, string $delimiter = null, string $enclosure = null)` | `string` | Builds a query string from an array of key value pairs, similar to [`http_build_query`](https://www.php.net/manual/en/function.http-build-query). Valid values for `$encoding` are `PHP_QUERY_RFC3986` (default) and `PHP_QUERY_RFC1738`, any other integer value will be interpreted as "no encoding" (`Query::NO_ENCODING`). | | `merge(string $uri, array $query)` | `string` | Merges additional query parameters into an existing query string. | | `parse(string $querystring, int $urlEncoding = null)` | `array` | Parses a query string into an associative array, similar to [`parse_str`](https://www.php.net/manual/en/function.parse-str) (without the inconvenient usage of a by-reference result variable). | | `recursiveRawurlencode(mixed $data)` | `array\|string` | Recursive [`rawurlencode`](https://www.php.net/manual/en/function.rawurlencode) | ### `MessageUtil` | method | return | info | |-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `getContents(MessageInterface $message)` | `string` | Reads the body content of a `MessageInterface` and makes sure to rewind. | | `decodeJSON(MessageInterface $message, bool $assoc = false)` | mixed | fetches the body of a `MessageInterface` and converts it to a JSON object (`stdClass`) or an associative array if `$assoc` is set to `true` and returns the result. | | `decodeXML(MessageInterface $message, bool $assoc = false)` | mixed | fetches the body of a `MessageInterface` and converts it to a `SimpleXMLElement` or an associative array if `$assoc` is set to `true` and returns the result. | | `toString(MessageInterface $message, bool $appendBody = true)` | `string` | Returns the string representation of an HTTP message. | | `toJSON(MessageInterface $message, bool $appendBody = true)` | `string` | Returns the string representation of an HTTP message. | | `decompress(MessageInterface $message)` | `string` | Decompresses the message content according to the `Content-Encoding` header (`compress`, `deflate`, `gzip`, `br`, `zstd`) and returns the decompressed data. `br` and `zstd` will throw a `RuntimeException` if the respecive extensions are missing. | | `setContentLengthHeader(MessageInterface $message)` | `MessageInterface` | Sets a Content-Length header in the given message in case it does not exist and body size is not null | | `setContentTypeHeader(MessageInterface $message, string $filename = null, string $extension = null)` | `MessageInterface` | Tries to determine the content type from the given values and sets the Content-Type header accordingly, throws if no mime type could be guessed. | | `setCookie(ResponseInterface $message, string $name, string $value = null, DateTimeInterface\|DateInterval\|int $expiry = null, string $domain = null, string $path = null, bool $secure = false, bool $httpOnly = false, string $sameSite = null)` | `ResponseInterface` | Adds a Set-Cookie header to a ResponseInterface (convenience) | | `getCookiesFromHeader(MessageInterface $message)` | `array\|null` | Attempts to extract and parse a cookie from a "Cookie" (user-agent) header | ### `UriUtil` | method | return | info | |------------------------------------------------------------------------|----------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `isDefaultPort(UriInterface $uri)` | `bool` | Checks whether the `UriInterface` has a port set and if that port is one of the default ports for the given scheme. | | `isAbsolute(UriInterface $uri)` | `bool` | Checks whether the URI is absolute, i.e. it has a scheme. | | `isNetworkPathReference(UriInterface $uri)` | `bool` | Checks whether the URI is a network-path reference. | | `isAbsolutePathReference(UriInterface $uri)` | `bool` | Checks whether the URI is a absolute-path reference. | | `isRelativePathReference(UriInterface $uri)` | `bool` | Checks whether the URI is a relative-path reference. | | `withoutQueryValue(UriInterface $uri, string $key)` | `UriInterface` | Removes a specific query string value. Any existing query string values that exactly match the provided `$key` are removed. | | `withQueryValue(UriInterface $uri, string $key, string $value = null)` | `UriInterface` | Adds a specific query string value. Any existing query string values that exactly match the provided `$key` are removed and replaced with the given `$key`-`$value` pair. A value of null will set the query string key without a value, e.g. "key" instead of "key=value". | | `parseUrl(string $url)` | `?array` | UTF-8 aware `\parse_url()` replacement. | ### `MimeTypeUtil` | method | return | info | |---------------------------------------|-----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `getFromExtension(string $extension)` | `?string` | Get the mime type for the given file extension (checks against the constant `chillerlan\HTTP\Utils\MIMETYPES`, a list of mime types from the [apache default config](http://svn.apache.org/repos/asf/httpd/httpd/branches/1.3.x/conf/mime.types)) | | `getFromFilename(string $filename)` | `?string` | Get the mime type from a file name | | `getFromContent(string $content)` | `?string` | Get the mime type from the given content | ### `StreamUtil` | method | return | info | |----------------------------------------------------------------------------------------------|------------|-----------------------------------------------------------------------------------------------------------------------------------------------------| | `getContents(string $extension)` | `string` | Reads the content from a stream and make sure we rewind | | `copyToStream(StreamInterface $source, StreamInterface $destination, int $maxLength = null)` | `int` | Copies a stream to another stream, starting from the current position of the source stream, reading to the end or until the given maxlength is hit. | | `tryFopen(string $filename, string $mode, $context = null)` | `resource` | Safely open a PHP resource, throws instead of raising warnings and errors | | `tryGetContents($stream, int $length = null, int $offset = -1)` | `string` | Safely get the contents of a stream resource, throws instead of raising warnings and errors | | `validateMode(string $mode)` | `string` | Checks if the given mode is valid for `fopen()` | | `modeAllowsReadWrite(string $mode)` | `bool` | Checks whether the given mode allows reading and writing | | `modeAllowsReadOnly(string $mode)` | `bool` | Checks whether the given mode allows only reading | | `modeAllowsWriteOnly(string $mode)` | `bool` | Checks whether the given mode allows only writing | | `modeAllowsRead(string $mode)` | `bool` | Checks whether the given mode allows reading | | `modeAllowsWrite(string $mode)` | `bool` | Checks whether the given mode allows writing | ### `ServerUtil` The `ServerUtil` object requires a set of [PSR-17 factories](https://www.php-fig.org/psr/psr-17/) on invocation, namely `ServerRequestFactoryInterface`, `UriFactoryInterface`, `UploadedFileFactoryInterface` and `StreamFactoryInterface`. It provides convenience methods to create server requests, URIs and uploaded files from the [superglobals](https://www.php.net/manual/en/language.variables.superglobals.php). | method | return | info | |-----------------------------------------------|------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `createServerRequestFromGlobals()` | `ServerRequestInterface` | Returns a ServerRequest object populated from the superglobals `$_GET`, `$_POST`, `$_COOKIE`, `$_FILES` and `$_SERVER`. | | `createUriFromGlobals()` | `UriInterface` | Creates an Uri populated with values from [`$_SERVER`](https://www.php.net/manual/en/reserved.variables.server) (`HTTP_HOST`, `SERVER_NAME`, `SERVER_ADDR`, `SERVER_PORT`, `REQUEST_URI`, `QUERY_STRING`). | | `normalizeFiles(array $files)` | `UploadedFileInterface[]` | Returns an `UploadedFile` instance array. | | `createUploadedFileFromSpec(array $value)` | `UploadedFileInterface` or `UploadedFileInterface[]` | Creates an UploadedFile instance from a `$_FILES` specification. If the specification represents an array of values, this method will delegate to `normalizeNestedFileSpec()` and return that return value. | | `normalizeNestedFileSpec(array $files):array` | `array` | Normalizes an array of file specifications. Loops through all nested files and returns a normalized array of `UploadedFileInterface` instances. | ### `Cookie` Implements a [HTTP cookie](https://datatracker.ietf.org/doc/html/rfc6265#section-4.1) | method | return | info | |------------------------------------------------------------------|----------|----------------------------------------------------------------| | `__construct(string $name, string $value = null)` | - | | | `__toString()` | `string` | returns the full cookie string to use in a `Set-Cookie` header | | `withNameAndValue(string $name, string $value)` | `Cookie` | | | `withExpiry(DateTimeInterface\|DateInterval\|int\|null $expiry)` | `Cookie` | | | `withDomain(string\|null $domain, bool $punycode = null)` | `Cookie` | | | `withPath(string\|null $path)` | `Cookie` | | | `withSecure(bool $secure)` | `Cookie` | | | `withHttpOnly(bool $httpOnly)` | `Cookie` | | | `withSameSite(string\|null $sameSite)` | `Cookie` | |
