Question

我使用以下代码作为对应于POST请求的控制器操作。

[HttpPost]
public HttpResponseMessage Post([FromBody]string value)
        {
            var response = new HttpResponseMessage(HttpStatusCode.Accepted)
            {
                Content = new StringContent(value, Encoding.UTF8, "text/xml")
            };
            return response;
        }

我正在使用Firefox的RESTClient插件生成请求。但是，每次值结果为null。请告诉我我做错了什么。

Fiddler收到的回复如下：

qwert

更新1：根据评论，我尝试了“value =”格式，但它也没有帮助。

value=qwert

上面的代码片段是新请求的小提取器。还试过JSON请求;但这也不起作用。

{"value"="qwert"}

Answer 1

在发出POST请求时，使用application / x-www-form-urlencoded作为内容类型。

POST请求中的内容为空
