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。
|
||
|
||
如果您觉得EasyHttp对您有用的话，别忘了给点个赞哦^_^ ！

本包是基于 [ gouguoyin/easyhttp ](https://gitee.com/gouguoyin/easyhttp "gitee.com/gouguoyin/easyhttp") 进行扩展开发，主要实现了以下扩展：
|
||
|
||
1. 增加 retry() 重试机制。
|
||
2. 增加 debug 日志调试功能。
|
||
3. 增加 withHost 指定服务端base_url
|
||
|
||
|
||
# 安装说明
|
||
|
||
#### 环境依赖
|
||
|
||
- PHP >= 7.2.5
|
||
- 如果使用PHP流处理，allow_url_fopen 必须在php.ini中启用。
|
||
- 如果使用cURL处理，cURL >= 7.19.4，并且编译了OpenSSL 与 zlib。
|
||
|
||
#### 一键安装

||
|
||
composer require yzh52521/easyhttp

use yzh52521\EasyHttp\RequestException;
|
||
|
||
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;
|
||
});
|
||
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}
|
||
|
||
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;
|
||
});
|
||
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(...);
|
||
```
|
||
|
||
#### 异步并发请求
|
||
|
||
```php
|
||
use yzh52521\EasyHttp\Response;
|
||
use yzh52521\EasyHttp\RequestException;
|
||
|
||
$promises = [
|
||
Http::getAsync('http://easyhttp.yzh52521.cn/api/sleep3.json'),
|
||
Http::getAsync('http1://easyhttp.yzh52521.cn/api/sleep1.json', ['name' => 'yzh52521']),
|
||
Http::postAsync('http://easyhttp.yzh52521.cn/api/sleep2.json', ['name' => 'yzh52521']),
|
||
];
|
||
|
||
Http::concurrency(10)->multiAsync($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：" . $e->getMessage() . PHP_EOL;
|
||
});
|
||
|
||
//输出
|
||
发起第 1 个请求失败，失败原因：cURL error 1: Protocol "http1" not supported or disabled in libcurl (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)
|
||
发起第 2 个异步请求，请求时长：2 秒
|
||
发起第 0 个异步请求，请求时长：3 秒
|
||
```
|
||
> 如果未调用concurrency()方法，并发次数默认为$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：
|
||
|
||
```php
|
||
$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：
|
||
|
||
```php
|
||
$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
|
||
|
||
```php
|
||
//传递一个日志类 thinkphp \think\facade\Log laravel Illuminate\Support\Facades\Log
|
||
Http::debug(Log::class)->post(...);
|
||
```
|
||
|
||
|
