如何让http客户端处理http方法删除和正文的响应

Question

.NET 对使用正文内容的 DELETE 请求不满意。使用我正在集成的 API，请求看起来像是正在发送，但响应总是超时。 WebClient 和 HttpClient 都会发生这种情况。 API 开发人员在其端看到请求并响应 200，但 HttpClient 未收到响应并超时。他们的 API def 有效，因为我已经使用邮递员和其他请求工具实现了它。

我尝试添加各种请求/响应标头。直接使用 HttpClient 和 WebRequest。我希望 API 能够做出任何回应。

DeleteWithPostAsync(string url, string json)
{
   HttpRequestMessage request = new 
   HttpRequestMessage(HttpMethod.Delete, url)
   {
    Content = new StringContent(json, Encoding.UTF8, 
    "application/json"),
     
   };

 var result = await 
 client.SendAsync(request).ConfigureAwait(false);
 var response = await 
 result.Content.ReadAsStringAsync().ConfigureAwait(false);
 return response;
}

.NET 在 WebApi 中发送和接收数据作为 DELETE 方法的响应时绝对没有问题。

这里是一个工作片段，您可以将其插入到控制器上，您只需使用

dotnet new webapi

即可创建。

我添加了一个 DELETE 方法，该方法采用

MyClass

类型的对象类并返回在另一个对象中提交的数据。

// this is an arbitrary class to send to DELETE method
public class MyClass
{
    public string Username { get; set; }        
}
    
// this is your code but with data and internal DELETE URL to call
[HttpGet("/stackoverflow/try")]
public async Task<object> DeleteWithPostAsync()
{
    // change this accordin with your local domanin and port
    var domainAndPort = "http://localhost:1234";
    
    var client = new HttpClient();
    //client.Timeout = TimeSpan.FromSeconds(10);

    HttpRequestMessage request = new 
        HttpRequestMessage(HttpMethod.Delete, 
            $"{domainAndPort}/stackoverflow/delete")
        {
            Content = new StringContent("{\"Username\": \"kiggyttass\"}", Encoding.UTF8, 
                "application/json")
        };

    var result = await 
        client.SendAsync(request).ConfigureAwait(false);
    var response = await 
        result.Content.ReadAsStringAsync().ConfigureAwait(false);
    
    return response;
}

// this simulates the delete API you call 
[HttpDelete("/stackoverflow/delete")]
public object DeletionAsync([FromBody] MyClass json)
{
    var obj = new
    {
        Message = $"Hey {json.Username}! deletion operation was completed successfully",
        Details = "No problems with that"
    };
    return Ok(obj);
}

当您调用 GET

/stackoverflow/try

方法时，它会调用 DELETE 方法并返回您想要的响应，如下所示：

{"message":"Hey kiggyttass! deletion operation was completed successfully","details":"No problems with that"}
