在Laravel 5.1中使用Guzzle进行GET

Question

我有一个API，并通过邮递员对其进行GET：

Ex.http://site/api/users.count

我有

{
    "status": 200,
    "message": "Success",
    "data": {
        "count": 8
    }
}

我尝试使用Guzzle：

composer require guzzlehttp/guzzle

Using version ^6.3 for guzzlehttp/guzzle

包括它

我将这两行添加到我的课程顶部

use GuzzleHttp\Exception\GuzzleException;
use GuzzleHttp\Client;

---

使用

$client = new Client();
$res = $client->request('GET','http://site/api/users.count');

---

结果

dd（$ res-> getStatusCode（））;

我有200

dd（$ res-> getBody（））;

Stream {#662 ▼
  -stream: stream resource @272 ▼
    wrapper_type: "PHP"
    stream_type: "TEMP"
    mode: "w+b"
    unread_bytes: 0
    seekable: true

    options: []
  }
  -size: null
  -seekable: true
  -readable: true
  -writable: true
  -uri: "php://temp"
  -customMetadata: []
}

dd（$ res）;

我有

预期结果

我希望得到类似的结果：

{
    "status": 200,
    "message": "Success",
    "data": {
        "count": 8
    }
}

我该如何调试？

Answer 1

您可以通过响应标题看到一切正常。状态代码为200，Content-Length不为0，等等。

响应的主体位于body的GuzzleHttp\Psr7\Response属性中，并且为GuzzleHttp\Psr7\Stream。您可以使用GuzzleHttp\Psr7\Stream方法访问它。

您可以使用getBody()从响应中读取read($n)字节，或通过隐式地（通过n）或显式地（使用强制转换运算符）将Stream强制转换为字符串来获取整个响应：

echo

供将来参考，您可以使用

var_dump((string) $res->getBody()); // explicitly
echo $res->getBody(); // implicitly

查看有关整个请求的更多信息：

debug mode

Answer 2

您必须使用$res = $client->request('GET','http://site/api/users.count', ["debug" => true]); ，您也可以执行以下操作$response->getBody();尝试查看其文档，有很多选择，但是要使用getBody函数获取内容

在您的确切情况下为->getStatusCode();
