使用Guzzle执行HTTP请求

Guzzle是一个PHP的HTTP客户端,用来轻而易举地发送请求,并集成到我们的WEB服务上。Guzzle提供了简单的接口,构建查询语句、POST请求、分流上传下载大文件、使用HTTP cookies、上传JSON数据等等。

安装

使用Composer安装:

composer require guzzlehttp/guzzle

或者编辑项目的composer.json文件,添加Guzzle作为依赖:

{
   "require": {
      "guzzlehttp/guzzle": "~6.0"
   }
}

然后执行composer update

Guzzle基本使用

发送请求

use GuzzleHttp\Client;

$client = new Client([
    // Base URI is used with relative requests
    'base_uri' => 'http://httpbin.org',
    // You can set any number of default request options.
    'timeout'  => 2.0,
]);

$response = $client->get('http://httpbin.org/get');
$response = $client->delete('http://httpbin.org/delete');
$response = $client->head('http://httpbin.org/get');
$response = $client->options('http://httpbin.org/get');
$response = $client->patch('http://httpbin.org/patch');
$response = $client->post('http://httpbin.org/post');
$response = $client->put('http://httpbin.org/put');

设置查询字符串

$response = $client->request('GET', 'http://httpbin.org?foo=bar');

或使用query请求参数来声明查询字符串参数:

$client->request('GET', 'http://httpbin.org', [
    'query' => ['foo' => 'bar']
]);

使用响应

获取状态码:

$code = $response->getStatusCode(); // 200
$reason = $response->getReasonPhrase(); // OK

判断头部信息:

if ($response->hasHeader('Content-Length')) {
    echo "It exists";
}

获取返回的头部信息:

echo $response->getHeader('Content-Length');

// Get all of the response headers.
foreach ($response->getHeaders() as $name => $values) {
    echo $name . ': ' . implode(', ', $values) . "\r\n";
}

使用getBody方法可以获取响应的主体部分(body),主体可以当成一个字符串或流对象使用

$body = $response->getBody();

可以将返回体转换成字符串或者直接以字符串形式读取:

$stringBody = (string) $body;
$content = $body->getContents();

上传文件

有时我们需要将文件传送到另一个web服务上去,可以使用post文件流形式将文件数据传送到指定web目录。

$filename = 'a.jpg';
$data = fopen($filename, 'r');
$res = $client->request('POST', 'http://localhost:9999/upload.php', ['body' => $data]);
$body = $res->getBody();
print_r($body->getContents());

接收上传文件的upload.php可以这样写:

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $data = file_get_contents('php://input');
    $file = file_put_contents('b.jpg', $data);
    if (FALSE === $file) {
        echo '上传成功';
    } else {
        echo '上传失败';
    }
}

提交表单

发送application/x-www-form-urlencoded POST请求需要你传入form_params 数组参数,数组内指定POST的字段。

$res = $client->request('POST', 'http://localhost:9999/form.php', [
    'form_params' => [
        'field_name' => 'abc',
        'other_field' => '123',
        'nested_field' => [
            'nested' => 'hello'
        ]
    ]
]);
$body = $res->getBody();
print_r((string)$body);

在接收端form.php使用$_POST即可获取上传的表单数据。

提交JSON数据

有时候我们在于API接口交互的时候需要将数据以特定的json格式传给api,可以这样写:

$res = $client->request('POST', 'http://localhost:9999/json.php', [
    'json' => ['foo' => 'bar']
]);

$body = $res->getBody();
print_r((string)$body);

接收端json.php使用file_get_contents('php://input')可获得提交的json数据。

使用Guzzle还可以发送异步请求以及并发请求,具体使用方法可参照Guzzle官方文档

其实我们在一些特殊场景下可以使用Swoole的协程特性实现异步的http客户端,功能非常强大。

-----------------------------------------------------------自己项目----------------------------------------------------

GuzzleHttp application/x-www-form-urlencoded 

headers 上加 Authorization

 $url = "http://xx.xx18.com/kxxord/bxxxupc";
        $key = "4283A7F1244D4172Axxxxxx";
        $headers = [
            'Content-Type'  => 'application/x-www-form-urlencoded',
            'Authorization' => $key,
        ];
        $client = new \GuzzleHttp\Client();
        $param = [
          'url'=>$domain_name,
          'page_index'=>1,
        ];
        $response = $client->request('POST', $url,['form_params'=>$param,'headers'=>$headers]);
        $response->getStatusCode(); // 200
        $response->getHeaderLine('content-type'); // 'application/json; charset=utf8'
//            $body = $response->getBody(); // '{"id": 1420053, "name": "guzzle", ...}'
        $data = json_decode($response->getBody(), true);

 

 

 

 

 

 $param_chinaz = [
                'key'=>$chinazApi_key,
                'keyword'=>$user['word_by_domain'],
                'domainName'=>$user['domain_name'],
            ];
            $response_chinaz = $client->request('POST', $china_url,['form_params'=>$param_chinaz,'connect_timeout' => 120]);
