【中文标题】查看 HttpClient.PostAsync 的响应正文【英文标题】:View response body for HttpClient.PostAsync 【发布时间】:2021-01-17 21:35:28 【问题描述】:我是 Postman 中的一个 POST,它生成以下 Curl:
curl --location --request POST 'https://authqa.cqi.newry.me.com/as/token.oauth2' \
--header 'Authorization: Basic QVBJX0JURUNSRUZEQVRBOlAzNkNEAAE3RVdGUzRPT0NLQlQ0SERaS1pGRTZHTksyQkNJTFVJWT0=' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Cookie: PF=mgvtuOC0jyPx3Lbrmw1hTX; BIGipServerauthqa-9031=1948242442.18211.0000' \
--data-urlencode 'grant_type=client_credentials' \
--data-urlencode 'charset=utf-8'
它返回以下正文:
"access_token": "generated_token",
"token_type": "Bearer",
"expires_in": 1799
我正在尝试使用 HttpClient
在 C# 中做同样的事情。
这是 POST 完成的地方:
var body = new StringContent("grant_type=client_credentials", Encoding.UTF8,
"application/x-www-form-urlencoded");
var httpResponseMessage = await _client.PostAsync("sa/token.oauth2", body);
我通过httpResponseMessage.ToString()
得到以下信息。
StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.HttpConnectionResponseContent, Headers:

Content-Type: application/json; charset=utf-8
我看不到上面发布的响应正文,但我怀疑它是Content: System.Net.Http.HttpConnectionResponseContent
。虽然不知道怎么看。谁能告诉我我如何看待上述身体?

这能回答你的问题吗? How to read HttpResponseMessage content as text 【参考方案1】:HttpClientResponse 包含内容,您可以这样阅读:
var body = new StringContent("grant_type=client_credentials", Encoding.UTF8,
"application/x-www-form-urlencoded");
var httpResponseMessage = await _client.PostAsync("sa/token.oauth2", body);
var responseContent = await httpResponseMessage.Content.ReadAsStringAsync(); // here you can read content as string
...
另请查看here 了解更多信息。
【讨论】:
【参考方案2】:httpResponseMessage.Content.ReadAsStringAsync().Result
会输出我想要的,但它被阻塞了。
var response = await client.PostAsync("sa/token.oauth2", body);
var content = await response.Content.ReadAsStringAsync();
请注意,您通常应该使用await
- 而不是.Result
。

请不要提倡异步 I/O 上的阻塞操作。以上是关于查看 HttpClient.PostAsync 的响应正文的主要内容,如果未能解决你的问题,请参考以下文章
