使用WCF RESTFul服务完整工作示例上载映像

Question

作为一个非常大的应用程序的一部分,我需要提供一个上传图像的REST服务.由于整个应用程序都是.NET,我一直在尝试找到一个WCF RESTFul服务的工作示例,它可以做到但不能(定义整个配置).网上有一些例子但我不能(由于我在WCF中缺乏知识)使它们都不起作用.(我不断抛出异常).

我很乐意与工作人员联系起来.

Answer 1

请在下面找到示例:

在服务器上:

接口:

[WebInvoke]
string PostImage(Stream stream);

我的实现类:

public string PostImage(Stream stream)
        {
            byte[] buffer = new byte[10000];
            stream.Read(buffer, 0, 10000);
            FileStream f = new FileStream("C:\\temp\\sample.jpg", FileMode.OpenOrCreate);
            f.Write(buffer, 0, buffer.Length);
            f.Close();
            stream.Close();
            return "Recieved the image on server";
        }

注意:确保您的WCF服务应用程序应用程序池标识具有对c:\ Temp位置的写访问权以写入该文件.或者,您可以替换逻辑以将映像保存到db或您希望的任何其他方式.

我在服务器上的web.config:

<services>
      <service name="XMLService.Service1" behaviorConfiguration="default">
        <endpoint address="" behaviorConfiguration="web" binding="webHttpBinding" bindingConfiguration="RestBinding" name="Service1" contract="XMLService.IService1" />
      </service>
</services>
<behaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp />
        </behavior>
  <serviceBehaviors>        
    <behavior name="default">
      <dataContractSerializer maxItemsInObjectGraph="2147483647" />
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<webHttpBinding>
<binding name="RestBinding">
     <readerQuotas maxStringContentLength="5242880" maxArrayLength="16384" maxBytesPerRead="4096" />
     <security mode="None">            
     </security>
     </binding>
</webHttpBinding>

现在我的客户端上有以下代码:

var client = new RestClient();
client.BaseUrl = "http://localhost/XMLService/Service1.svc";
var request = new RestRequest(method) { DateFormat = DataFormat.Xml.ToString(), Resource = resourceUrl };
if(requestBody !=null)
      request.AddParameter("objCompositeType", requestBody);
request.AddFile("stream", image, "Array.png");    
var response = client.Execute(request);
string responseString;
if (response.StatusCode == HttpStatusCode.OK)
{
     responseString = HttpUtility.HtmlDecode(response.Content);
}
else
{
     responseString = response.StatusDescription + " --------------------" + HttpUtility.HtmlDecode(response.Content);
}

我正在使用第三方工具RestSharp将我的请求发布到REST服务.

我在提琴手中的请求如下所示:
