通过HttpClient发送PUT请求到Saucelabs没有响应

Question

我想通过their API发送PUT请求更新Saucelabs的作业。但是，下面的代码挂起，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> 

为什么这个请求挂起，我能做些什么，使之成功？

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

为什么这个请求挂起，我该怎么做才能使它成功？

最有可能是在client.SendAsync方法异步和阻塞调用像.Result这可能会导致死锁或者你把它，原因代码挂的混合。

考虑使用await一直使该方法调用异步。

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(); 
    } 
}
