Question

我通过传递requestUri和内容来使用HttpClient PostAsync方法，但是得到了非常普通的错误消息：

发生一个或多个错误

能不能请我指导。不知道是什么原因造成的。当我在邮递员中使用相同的requestUri和内容时，它会按预期工作。

var client = new HttpClient();
var content = new StringContent(authXML);
content.Headers.ContentType = new MediaTypeHeaderValue("application/xml");
client.BaseAddress = new Uri(authorizationUri);
var result = client.PostAsync(authorizationUri, content).Result; //Generic error message "One or more errors occurred"
if (response.IsSuccessStatusCode)
{
    // SUCCESS
    // Do Something
}
else
{
    // ERROR
    // Do Something
}

Answer 1

提供的代码示例似乎无法获得响应句柄。我认为您需要获取响应，然后将其应用于结果，如下所示：

string result;
var response = client.PostAsync(authorizationUri, content).Result;
response.EnsureSuccessStatusCode();
result = response.Content.ReadAsStringAsync().Result;

Answer 2

您需要等待或等待结果。

编辑：发生的一个或多个错误是任务的聚集异常。您可能需要内部
