Question

我有这个

{“发票”：{“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“ ： “主”}]}

现在我想使用rest在我的服务器上传递它并将其转换为流。我的服务代码在这里。 https://stackoverflow.com/questions/9594382/convert-json-to-stream-in-wcf

请找一些示例代码以使您的方案正常运行：

在我的服务器上：

[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);
        }

我修改了服务器方法逻辑，以便我可以测试它。在服务器上获取流后，您可以根据需要使用逻辑返回发票对象。

现在在客户端调用其余服务我使用以下代码：

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);
}

将jsonstring传递给服务并将其转换为服务器端的流
