c# – 通过HttpClient向Paucelabs发送PUT请求没有响应

我试图发送一个PUT请求通过their API更新Saucelabs上的作业.但是,以下代码挂起,我不知道为什么.

using (var client = new HttpClient())
{
    var sessionId = Browser.Driver.GetSessionId();
    var uri = new Uri($"https://saucelabs.com/rest/v1/{Configuration.SauceUserName}/jobs/{sessionId}");
    var uriWithCred =
        new UriBuilder(uri)
        {
            UserName = $"{Configuration.SauceUserName}",
            Password = $"{Configuration.SauceAccessKey}"
        }.Uri;
    var payload = new StringContent($"{{\"name\":\"{TestMethodName}\"}}", Encoding.UTF8, "application/json");
    var request = new HttpRequestMessage
    {
        Method = HttpMethod.Put,
        RequestUri = uriWithCred,
        Content = payload
    };
    var response = client.SendAsync(request).Result;                
}

以下cUrl请求成功(当然是编辑凭据).

curl -X PUT -s -u <username>:<access-key> 
-d "{\"name\": \"test name\"}"
https://saucelabs.com/rest/v1/<username>/jobs/<job-id>

为什么这个请求会挂起,我该怎么做才能使它成功？

由于与问题无关的原因,我无法在设置WebDriver的功能时设置作业的名称.

解决方法:

Why does this request hang and what can I do to make it successful?

很可能是在客户端上混合了异步和阻塞调用,如.Result.SendAsync方法可能会导致死锁,或者当你放置它时,导致代码挂起.

考虑使用await使方法调用异步.

public async Task CallAPIAsync() {    
    using (var client = new HttpClient()) {
        var sessionId = Browser.Driver.GetSessionId();
        var uri = new Uri($"https://saucelabs.com/rest/v1/{Configuration.SauceUserName}/jobs/{sessionId}");
        var uriWithCred =
            new UriBuilder(uri) {
                UserName = $"{Configuration.SauceUserName}",
                Password = $"{Configuration.SauceAccessKey}"
            }.Uri;
        var payload = new StringContent($"{{\"name\":\"{TestMethodName}\"}}", Encoding.UTF8, "application/json");
        var request = new HttpRequestMessage {
            Method = HttpMethod.Put,
            RequestUri = uriWithCred,
            Content = payload
        };
        var response = await client.SendAsync(request);

        var content = await response.Content.ReadAsStringAsync();
    }
}
