WCF restful 服务:如何在 POST 请求中发送长字符串参数?

WCF restful service: How to send long string parameters in POST requests?

我的resful wcf服务中有这种方法: 服务合同-

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "CreateTask?t={token}&title={title}&aun={assigneeUsername}&inst={instructions}&tnum={taskNumber}&pr={priority}&ud={userData}")]
Stream CreateTask(string token, string title, string assigneeUsername, string instructions, string taskNumber,
                        string priority, string userData);

服务class:

public Stream CreateTask(string token, string title, string assigneeUsername, string instructions, string taskNumber,
                        string priority, string userData)
{...}

有些参数可以是很长的字符串 (~5000),我不希望它们成为查询字符串的一部分,可能会将其中一些作为 FormUrlEncodedContent 发送。

如何将一些参数作为 URL 的一部分发送,而将其他参数作为 content/ 发送到正文中? 我的运营合同可以这样吗?:

[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "CreateTask?t={token}")]
Stream CreateTask(string token, string title, string assigneeUsername, string instructions, string taskNumber,
                        string priority, string userData);

我的客户端代码应该是什么样的?

客户端只需要将 json 格式的值发送为 HttpContent:

HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost/MyService/Tasks.svc/");

var url = string.Format("CreateTask?t={0}&ud={1}", token, userData);

var myObject = (dynamic)new JObject();
myObject.title = title;
myObject.assigneeUsername = assigneeUsername;
myObject.instructions = instructions;
myObject.taskNumber = taskNumber;
myObject.priority = priority;

HttpResponseMessage response = client.PostAsync(url, new StringContent(myObject.ToString(), Encoding.UTF8, "application/json")).Result;
