This fork is maintained by APIMatic for its Code Generator as a Service.

Features

• Automatic JSON parsing into a native object for JSON responses
• Response data class to store http response information
• Supports form parameters, file uploads and custom body entities
• Supports gzip
• Supports Basic, Digest, Negotiate, NTLM Authentication natively
• Configuration class manage all the HttpClient's configurations
• Customizable timeout
• Customizable retries and backoff
• Customizable default headers for every request (DRY)

Supported PHP Versions

• PHP 7.2
• PHP 7.4
• PHP 8.0

Installation

To install apimatic/unirest-php with Composer, just add the following to your composer.json file:

or by running the following command:

Usage

Creating a HttpClient with Default Configurations

You can create a variable at class level and instantiate it with an instance of HttpClient, like:

Creating a HttpClient with Custom Configurations

To create a client with custom configurations you first required an instance of Configuration, and then add it to the HttpClient during its initialization, like:

This Configuration instance can further be customized by setting properties like: maximumRetryWaitTime, verifyPeer, defaultHeaders, etc. Check out Advanced Configuration for more information.

Creating a Request

After the initialization of HttpClient, you will be needing an instance of Request that is required to be exchanged as Response.

Let's look at a working example of sending the above request:

JSON Requests (application/json)

A JSON Request can be constructed using the Unirest\Request\Body::Json helper:

Notes:

• Content-Type headers will be automatically set to application/json
• the data variable will be processed through json_encode with default values for arguments.
• an error will be thrown if the JSON Extension is not available.

Form Requests (application/x-www-form-urlencoded)

A typical Form Request can be constructed using the Unirest\Request\Body::Form helper:

Notes:

• Content-Type headers will be automatically set to application/x-www-form-urlencoded
• the final data array will be processed through http_build_query with default values for arguments.

Multipart Requests (multipart/form-data)

A Multipart Request can be constructed using the Unirest\Request\Body::Multipart helper:

Notes:

• Content-Type headers will be automatically set to multipart/form-data.
• an auto-generated --boundary will be set.

Multipart File Upload

simply add an array of files as the second argument to to the Multipart helper:

If you wish to further customize the properties of files uploaded you can do so with the Unirest\Request\Body::File helper:

Note: we did not use the Unirest\Request\Body::multipart helper in this example, it is not needed when manually adding files.

Custom Body

Sending a custom body such rather than using the Unirest\Request\Body helpers is also possible, for example, using a serialize body string with a custom Content-Type:

Authentication

For Authentication you need httpClient instance with custom configurations, So, create Configuration instance like:

The third parameter, which is a bitmask, will Unirest which HTTP authentication method(s) you want it to use for your proxy authentication.

If more than one bit is set, Unirest (at PHP's libcurl level) will first query the site to see what authentication methods it supports and then pick the best one you allow it to use. For some methods, this will induce an extra network round-trip.

Supported Methods

Cookies

Set a cookie string to specify the contents of a cookie header. Multiple cookies are separated with a semicolon followed by a space (e.g., "fruit=apple; colour=red")

Set a cookie file path for enabling cookie reading and storing cookies across multiple sequence of requests.

$cookieFile must be a correct path with write permission.

Response Object

Upon receiving a response Unirest returns the result in the form of an Object, this object should always have the same keys for each language regarding to the response details.

• getStatusCode() - HTTP Response Status Code (Example 200)
• getHeaders() - HTTP Response Headers
• getBody() - Parsed response body where applicable, for example JSON responses are parsed to Objects / Associative Arrays.
• getRawBody() - Un-parsed response body

Advanced Configuration

You can set some advanced configuration to tune Unirest-PHP:

Custom JSON Decode Flags

Unirest uses PHP's JSON Extension for automatically decoding JSON responses. sometime you may want to return associative arrays, limit the depth of recursion, or use any of the customization flags.

To do so, simply set the desired options using the jsonOpts request method:

Timeout

You can set a custom timeout value (in seconds):

Retries Related

Proxy

Set the proxy to use for the upcoming request.

you can also set the proxy type to be one of CURLPROXY_HTTP, CURLPROXY_HTTP_1_0, CURLPROXY_SOCKS4, CURLPROXY_SOCKS5, CURLPROXY_SOCKS4A, and CURLPROXY_SOCKS5_HOSTNAME.

check the cURL docs for more info.

Proxy Authentication

Passing a username, password (optional), defaults to Basic Authentication:

The third parameter, which is a bitmask, will Unirest which HTTP authentication method(s) you want it to use for your proxy authentication.

If more than one bit is set, Unirest (at PHP's libcurl level) will first query the site to see what authentication methods it supports and then pick the best one you allow it to use. For some methods, this will induce an extra network round-trip.

See Authentication for more details on methods supported.

Default Request Headers

You can set default headers that will be sent on every request:

You can set default headers in bulk by passing an array:

You can clear the default headers anytime with:

Default cURL Options

You can set default cURL options that will be sent on every request:

You can set options bulk by passing an array:

You can clear the default options anytime with:

SSL validation

You can explicitly enable or disable SSL certificate validation when consuming an SSL protected endpoint:

By default is true.
