HTTP客户端

简介

EasyHttp 是一个轻量级、语义化、对IDE友好的HTTP客户端，支持常见的HTTP请求、异步请求和并发请求，让你可以快速地使用 HTTP 请求与其他 Web 应用进行通信。

EasyHttp并不强制依赖于cURL，如果没有安装cURL，EasyHttp会自动选择使用PHP流处理，或者你也可以提供自己的发送HTTP请求的处理方式。

安装

composer require yzh52521/easyhttp

使用

发起请求

同步请求

常规请求

$response = Http::get('http://httpbin.org/get');

$response = Http::get('http://httpbin.org/get?name=yzh52521');

$response = Http::get('http://httpbin.org/get?name=yzh52521', ['age' => 18]);

$response = Http::post('http://httpbin.org/post');

$response = Http::post('http://httpbin.org/post', ['name' => 'yzh52521']);

$response = Http::patch(...);

$response = Http::put(...);

$response = Http::delete(...);

$response = Http::head(...);

$response = Http::options(...);

指定服务端base_url的请求

// 指定服务端base_url地址,最终请求地址为 https://serv.yzh52521.com/login
$response = Http::withHost('https://serv.yzh52521.com')->post('/login');

发送原始数据（Raw）请求

$response = Http::withBody(
    base64_encode($photo), 'image/jpeg'
)->post(...);

发送 Content-Type 编码请求

// application/x-www-form-urlencoded(默认)
$response = Http::asForm()->post(...);

// application/json
$response = Http::asJson()->post(...);

发送 Multipart 表单请求

$response = Http::asMultipart(
    'file_input_name', file_get_contents('photo1.jpg'), 'photo2.jpg'
)->post('http://test.com/attachments');

$response = Http::asMultipart(
    'file_input_name', fopen('photo1.jpg', 'r'), 'photo2.jpg'
)->post(...);

$response = Http::attach(
    'file_input_name', file_get_contents('photo1.jpg'), 'photo2.jpg'
)->post(...);

$response = Http::attach(
    'file_input_name', fopen('photo1.jpg', 'r'), 'photo2.jpg'
)->post(...);

表单enctype属性需要设置成 multipart/form-data

携带请求头的请求

$response = Http::withHeaders([
    'x-powered-by' => 'yzh52521'
])->post(...);

携带重定向的请求

// 默认
$response = Http::withRedirect(false)->post(...);

$response = Http::withRedirect([
    'max'             => 5,
    'strict'          => false,
    'referer'         => true,
    'protocols'       => ['http', 'https'],
    'track_redirects' => false
])->post(...);

$response = Http::maxRedirects(5)->post(...);

携带认证的请求

// Basic认证
$response = Http::withBasicAuth('username', 'password')->post(...);

// Digest认证(需要被HTTP服务器支持)
$response = Http::withDigestAuth('username', 'password')->post(...);

携带 User-Agent 的请求

$response = Http::withUA('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3100.0 Safari/537.36')->post(...);

携带Token令牌的请求

$response = Http::withToken('token')->post(...);

携带认证文件的请求

$response = Http::withCert('/path/server.pem', 'password')->post(...);

携带SSL证书的请求

// 默认
$response = Http::withVerify(false)->post(...);

$response = Http::withVerify('/path/to/cert.pem')->post(...);

携带COOKIE的请求

$response = Http::withCookies(array $cookies, string $domain)->post(...);

携带协议版本的请求

$response = Http::withVersion(1.1)->post(...);

携带代理的请求

$response = Http::withProxy('tcp://localhost:8125')->post(...);

$response = Http::withProxy([
    'http'  => 'tcp://localhost:8125', // Use this proxy with "http"
    'https' => 'tcp://localhost:9124', // Use this proxy with "https",
    'no'    => ['.com.cn', 'yzh52521.cn'] // Don't use a proxy with these
])->post(...);

设置超时时间(单位秒)

$response = Http::timeout(60)->post(...);

设置等待服务器响应超时的最大值(单位秒)

$response = Http::connectTimeout(60)->post(...);

设置延迟时间(单位秒)

$response = Http::delay(60)->post(...);

设置并发次数

$response = Http::concurrency(10)->promise(...);

重发请求，设置retry方法。重试次数/两次重试之间的时间间隔（毫秒）：

$response = Http::retry(3, 100)->post(...);

响应的主体部分将要保存的位置

$response = Http::sink('/path/to/file')->post(...);

Guzzle 中间件

use GuzzleHttp\Middleware;
use Psr\Http\Message\RequestInterface;
use Psr\Http\Message\ResponseInterface;

$response = Http::withMiddleware(
    Middleware::mapRequest(function (RequestInterface $request) {
        $request = $request->withHeader('X-Example', 'Value');
        return $request;
    })
)->get('http://example.com');

………………
$response = Http::withRequestMiddleware(
    function (RequestInterface $request) {
        $request = $request->withHeader('X-Example', 'Value');
        return $request;
    }
)->get('http://example.com');

………………

$response = Http::withResponseMiddleware(
    function (RequestInterface $response) {
        $response = $response->getHeader('X-Example');
        return $response;
    }
)->get('http://example.com');

异步请求

use yzh52521\EasyHttp\Response;
use yzh52521\EasyHttp\RequestException;

$promise = Http::getAsync('http://easyhttp.yzh52521.cn/api/sleep3.json', ['token' => TOKEN], function (Response $response) {
    echo '异步请求成功，响应内容：' . $response->body() . PHP_EOL;
}, function (RequestException $e) {
    echo '异步请求异常，错误码：' . $e->getCode() . '，错误信息：' . $e->getMessage() . PHP_EOL;
});
$promise->wait();
echo json_encode(['code' => 200, 'msg' => '请求成功'], JSON_UNESCAPED_UNICODE) . PHP_EOL;

//输出
{"code":200,"msg":"请求成功"}
异步请求成功，响应内容：{"code":200,"msg":"success","second":3}

$promise =Http::getAsync('http1://easyhttp.yzh52521.cn/api/sleep3.json', function (Response $response) {
    echo '异步请求成功，响应内容：' . $response->body() . PHP_EOL;
}, function (RequestException $e) {
    echo '异步请求异常，错误信息：' . $e->getMessage() . PHP_EOL;
});
 $promise->wait();
echo json_encode(['code' => 200, 'msg' => '请求成功'], JSON_UNESCAPED_UNICODE) . PHP_EOL;

//输出
{"code":200,"msg":"请求成功"}
异步请求异常，错误信息：cURL error 1: Protocol "http1" not supported or disabled in libcurl (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

Http::postAsync(...);

Http::patchAsync(...);

Http::putAsync(...);

Http::deleteAsync(...);

Http::headAsync(...);

Http::optionsAsync(...);

使用 等待异步回调处理完成
Http::wait();

异步并发请求

use yzh52521\EasyHttp\Response;
use yzh52521\EasyHttp\RequestException;

$promises = [
    Http::getAsync('http://easyhttp.yzh52521.cn/api/sleep3.json'),
    Http::getAsync('http1://easyhttp.yzh52521.cn/api/sleep1.json', ['name' => 'yzh52521']),
    Http::postAsync('http://easyhttp.yzh52521.cn/api/sleep2.json', ['name' => 'yzh52521']),
];

$pool =Http::concurrency(10)->multiAsync($promises, function (Response $response, $index) {
    echo "发起第 $index 个异步请求，请求时长：" . $response->json()->second . '秒' . PHP_EOL;
}, function (RequestException $e, $index) {
    echo "发起第 $index 个请求失败，失败原因：" . $e->getMessage() . PHP_EOL;
});

$promise = $pool->promise();
$promise->wait();

//输出
发起第 1 个请求失败，失败原因：cURL error 1: Protocol "http1" not supported or disabled in libcurl (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)
发起第 2 个异步请求，请求时长：2 秒
发起第 0 个异步请求，请求时长：3 秒

如果未调用concurrency()方法，并发次数默认为$promises的元素个数，$promises数组里必须是异步请求

使用响应

发起请求后会返回一个 yzh52521\EasyHttp\Response $response的实例，该实例提供了以下方法来检查请求的响应：

$response->body() : string;
$response->json() : object;
$response->array() : array;
$response->status() : int;
$response->ok() : bool;
$response->successful() : bool;
$response->serverError() : bool;
$response->clientError() : bool;
$response->headers() : array;
$response->header($header) : string;

异常处理

请求在发生客户端或服务端错误时会抛出 yzh52521\EasyHttp\RequestException $e异常，该实例提供了以下方法来返回异常信息：

$e->getCode() : int;
$e->getMessage() : string;
$e->getFile() : string;
$e->getLine() : int;
$e->getTrace() : array;
$e->getTraceAsString() : string;

调试日志

有时候难免要对 Http 的请求和响应包体进行记录以方便查找问题或做什么

//传递一个日志类
 thinkphp  \think\facade\Log 
 laravel  Illuminate\Support\Facades\Log  
 webman support\Log
Http::debug(Log::class)->post(...);
