传递一个jsonstring到服务，并将其转换到服务器端

Question

我有这个

{“发票”流：{“POSWorkstationID”：“POS7”，“POSClerkID”：“管理”，“客户名称” ：“爱丽丝漫游仙境”，“IsFreightOverwrite”：true}，“invoiceDetails”：[{“ItemDescription”：“旧世界灯柱”，“QuantityOrdered”：“1”，“SalePriceRate”：“107.99美元”，“ExtPriceRate” ：“107.99”，“ItemType”：“股票”，“LineNum”：1，“WarehouseCode”：“主”}]}

现在我想通过这个在我的服务器上使用休息并将其转换为流。我的服务代码在这里。 https://stackoverflow.com/questions/9594382/convert-json-to-stream-in-wcf

请找一些示例代码，让您的工作场景：

在我的服务器：

[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)] 
     public string CreateInvoice(Stream xmlStream) 
     { 
      byte[] buffer = new byte[WebOperationContext.Current.IncomingRequest.ContentLength]; 
      int read = -1; 
      while (read != 0) 
      { 
       read = xmlStream.Read(buffer, 0, buffer.Length); 
      }   
      System.Text.Encoding enc = System.Text.Encoding.ASCII; 
      string jsonobjectstring = enc.GetString(buffer); 
      JavaScriptSerializer json = new JavaScriptSerializer(); 
      object jsonobject = json.DeserializeObject(jsonobjectstring); 
      return "Recieved the json text on server"; 
      //MaintainInvoice(xmlStream, InvoiceMaintainance.CreateInvoice); 
     } 

我已经修改了服务器的方法，逻辑，这样我就可以测试它。一旦在服务器上获得流，您可以根据需要使用逻辑返回发票对象。

在客户端我们可以调用其他服务，我使用下面的代码：

private string UseHttpWebApproachByteArray(string serviceUrl, string resourceUrl, string method, byte[] requestBody) 
     { 
      string responseMessage = null;    
      var request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest; 
      if (request != null) 
      {     
       request.ContentType = "application/octet-stream"; 
       request.Method = method; 
      }    
      if (method == "POST" && requestBody != null) 
      {     
       request.ContentLength = requestBody.Length; 
       using (Stream postStream = request.GetRequestStream())      
        postStream.Write(requestBody, 0, requestBody.Length); 
      } 

      if (request != null) 
      { 
       var response = request.GetResponse() as HttpWebResponse; 
       if (response.StatusCode == HttpStatusCode.OK) 
       { 
        Stream responseStream = response.GetResponseStream(); 
        if (responseStream != null) 
        { 
         var reader = new StreamReader(responseStream); 

         responseMessage = reader.ReadToEnd(); 
        } 
       } 
       else 
       { 
        responseMessage = response.StatusDescription; 
       } 
      } 
      return responseMessage; 
     } 

private void Test() 
{ 
     string jsonText = "{\"invoices\":{\"POSWorkstationID\":\"POS7\",\"POSClerkID\":\"admin\",\"CustomerName\":\"Alice in Wonderland Tours\",\"IsFreightOverwrite\":true},\"invoiceDetails\":[{\"ItemDescription\":\"Old World Lamppost\",\"QuantityOrdered\":\"1\",\"SalePriceRate\":\" $107.99\",\"ExtPriceRate\":\"107.99\",\"ItemType\":\"Stock\",\"LineNum\":1,\"WarehouseCode\":\"Main\"}]}"; 
     System.Text.Encoding enc = System.Text.Encoding.ASCII; 
     byte[] jsonBytes = enc.GetBytes(jsonText); 
     UseHttpWebApproachByteArray(serviceBaseUrl, resourceUrl, method, jsonBytes); 
}
