Question

在通用的Windows应用程序的参数一起发布JSON值

例如：

交 http://sampleurl?param=1&param2=1 JSON体：[{”关键 “：” 值”， “KEY2”： “值2”}]

Answer 1

，我们可以创建参数词典，并张贴作为formcontent

public static async Task<string> postdataAsync(Uri posturl, Dictionary<string, string> pairs) 
    { 
     string response = ""; 
     try 
     { 
      var filter = new HttpBaseProtocolFilter(); 
      filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.Expired); 
      filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.Untrusted); 
      filter.IgnorableServerCertificateErrors.Add(ChainValidationResult.InvalidName); 
      HttpClient httpClient = new HttpClient(filter); 
      Windows.Web.Http.HttpFormUrlEncodedContent formContent = new Windows.Web.Http.HttpFormUrlEncodedContent(pairs); 
      HttpResponseMessage httpresponse = await httpClient.PostAsync(posturl, formContent); 
      response = await httpresponse.Content.ReadAsStringAsync(); 
     } 
     catch 
     { 
      return null; 

     } 
     return response; 

    }
