Guzzlehttp - 如何从 Guzzle 6 获得响应的正文?
Guzzlehttp - How get the body of a response from Guzzle 6?
我正在尝试围绕我公司正在开发的 api 编写一个包装器。它是 restful,使用 Postman,我可以将 post 请求发送到像 http://subdomain.dev.myapi.com/api/v1/auth/
这样的端点,用户名和密码作为 POST 数据,我会得到一个令牌。一切都按预期工作。现在,当我尝试从 PHP 执行相同操作时,我得到了一个 GuzzleHttp\Psr7\Response
对象,但似乎无法像我对 Postman 请求所做的那样在其中的任何地方找到令牌。
相关代码如下:
$client = new Client(['base_uri' => 'http://companysub.dev.myapi.com/']);
$response = $client->post('api/v1/auth/', [
'form_params' => [
'username' => $user,
'password' => $password
]
]);
var_dump($response); //or $resonse->getBody(), etc...
上面代码的输出看起来像(警告,传入的文本墙):
object(guzzlehttp\psr7\response)#36 (6) {

string(2) "ok"

Postman 的输出类似于:

"token" "fasdfasf-asfasdfasdf-sfasfasf"
}
}
很明显,我遗漏了一些有关在 Guzzle 中使用响应对象的信息。 Guzzle 响应指示请求中的 200 状态代码,因此我不确定我需要做什么来检索返回的数据。
Guzzle 实现了使用 PHP 临时流的 PSR-7. That means that it will by default store the body of a message in a Stream。要检索所有数据,您可以使用转换运算符:
$contents = (string) $response->getBody();
您也可以使用
$contents = $response->getBody()->getContents();
两种方法的区别在于getContents
returns剩余的内容,所以第二次调用returns什么都没有,除非你用[=15寻找流的位置=] 或 seek
.
$stream = $response->getBody();
$contents = $stream->getContents(); // returns all the contents
$contents = $stream->getContents(); // empty string
$stream->rewind(); // Seek to the beginning
$contents = $stream->getContents(); // returns all the contents
相反,使用 PHP 的字符串转换操作,它将从流中读取所有数据,直到到达末尾。
$contents = (string) $response->getBody(); // returns all the contents
$contents = (string) $response->getBody(); // returns all the contents
如果期待 JSON 返回,最简单的获取方式:
$data = json_decode($response->getBody()); // returns an object
// OR
$data = json_decode($response->getBody(), true); // returns an array
json_decode()
会自动将正文投射到string
,所以不需要调用getContents()
.
获取 JSON 格式的响应:
1.
$response = (string) $res->getBody();
$response =json_decode($response); // Using this you can access any key like below
$key_value = $response->key_name; //access key
$response = json_decode($res->getBody(),true);
$key_value = $response['key_name'];//access key
