无法使用 Symfony HttpClient 检索错误消息 [英] Cannot retrieve error message using Symfony HttpClient

问题描述

我使用 Symfony HttpClient 来调用外部 api.当 statusCode 为 200 时，我可以使用 getContent() 方法来检索 API 响应.如果 API 响应为 400，则抛出 ClientException 并且我无法获取外部 API 消息.

I use Symfony HttpClient to call an external api. When the stastusCode is 200 I can use getContent() method to retrieve the API response. If the API response is 400 ClientException is thrown and I cannot get the external API message.

$httpClient = HttpClient::create();
$response = $httpClient->request($method, $url);
if (200 !== $response->getStatusCode()) {
    $apiResponse['statusCode'] = $response->getStatusCode();
    $httpInfo = $response->getInfo();
    $content = $response->getContent(); //this throws ClientException
}

推荐答案

可以使用

$response->getContent(false)

得到响应而不是抛出错误.

to get the response and not an error thrown.

代码说明:

    public function getContent(bool $throw = true): string

请注意，您在这里失去了 HttpClient 为您提供的一些非常有意义的包装功能.

Note that you lose a bit of the very meaningful wrapping functionality HttpClient provides you here.
