傳遞一個jsonstring到服務，並將其轉換到服務器端

Question

我有這個

{「發票」流：{「POSWorkstationID」：「POS7」，「POSClerkID」：「管理」，「客戶名稱」 ：「愛麗絲漫遊仙境」，「IsFreightOverwrite」：true}，「invoiceDetails」：[{「ItemDescription」：「舊世界燈柱」，「QuantityOrdered」：「1」，「SalePriceRate」：「107.99美元」，「ExtPriceRate」 ：「107.99」，「ItemType」：「股票」，「LineNum」：1，「WarehouseCode」：「主」}]}

現在我想通過這個在我的服務器上使用休息並將其轉換爲流。我的服務代碼在這裏。 https://stackoverflow.com/questions/9594382/convert-json-to-stream-in-wcf

請找一些示例代碼，讓您的工作場景：

在我的服務器：

[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); 
     } 

我已經修改了服務器的方法，邏輯，這樣我就可以測試它。一旦在服務器上獲得流，您可以根據需要使用邏輯返回發票對象。

在客戶端我們可以調用其他服務，我使用下面的代碼：

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); 
}
