问题描述
我正在尝试发送 POST 请求.虽然通过 POSTMAN 发送一切顺利，然后我尝试通过 C# 代码发送:
I'm trying to send POST request. While sending via POSTMAN all goes well, then I try to send it by C# code:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
var client = new RestClient(MY-URL);
var request = new RestRequest(Method.POST);
request.Credentials = new System.Net.NetworkCredential(ServerUsername, Password);
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");
request.AddParameter("undefined", My JSON Data, ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
我收到此错误:
请求包含实体主体，但没有 Content-Type 标头.此资源不支持推断的媒体类型application/octet-stream"
The request contains an entity body but no Content-Type header. The inferred media type 'application/octet-stream' is not supported for this resource
我该如何解决?
推荐答案
试写:
Content-Type: application/json; charset=UTF-8"
或添加到您的标题中:
Accept: application/json
