wcf webHttpBinding Post 大数据量提交 ios c＃客户端

一直在为安卓和苹果写服务，刚开始的时候全用的Get请求用url传所有的参数，由于url长度的限制大的数据量

无法传到服务器，提交图片什么的就更不用说了，后来用的POST请求，记录一下，做了一个很简单的小例子：

c#源代码提供大家下载 10Solution4.rar

ios代码 IOSHttpPostDemo.rar

 开始做吧！

1建一个空工程Solution4，添加一个类库WcfSerDemo引入

System.ServiceModel  和System.ServiceModel.Web两个类库

建一个接口IMyWcfServerMethod

?

[ServiceContract]

public interface IMyWcfServerMethod

{　　　　

    [OperationContract, WebInvoke(Method = "POST", UriTemplate = "postMostStr/{streamLength}", BodyStyle = WebMessageBodyStyle.Bare)]

    string postMostStr(string streamLength, Stream getStream);

 

    //实验一下接收

    [OperationContract, WebInvoke( Method="GET", UriTemplate = "postText")]

    string postText();

}

我们只用 postMostStr这个方法它是以POST形式接收的Url只要一个参数就是传过来的byte的长度

那个Stream类型的台数就是Post过来的数据

建一个类实现这个接口MyWcfServerMethodFace

?

public class MyWcfServerMethodFace:IMyWcfServerMethod

    {

        public string postMostStr(string streamLength, System.IO.Stream getStream)

        {

            try

            {  

                int byLength=Convert.ToInt32(streamLength);

                byte[] resultByte = new byte[byLength];

                getStream.Read(resultByte, 0, resultByte.Length);//把接收的stream写到resultByte

                Console.WriteLine(Encoding.UTF8.GetString(resultByte));//把收到的数据输出到控制台

 

            }

            catch (Exception ex)

            {

                Console.WriteLine(ex.ToString());

            }

            Console.WriteLine("success!");

            return "success!";

        }

 

        public string postText()

        {

            Console.WriteLine("text!");

            return "text success";

            

        }

    }

好了契约就写好了，宿主程序就用控制台程序

加一个控制程序

引入System.ServiceModel 和 WcfSerDemo

配制App.config

?

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

  <system.serviceModel>

    <bindings>

      <webHttpBinding><!--这个是接收大数据加的-->

        <binding name="webBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">

          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"

                        maxArrayLength="2147483647" maxBytesPerRead="2147483647"

                        maxNameTableCharCount="2147483647"/>

        </binding>

      </webHttpBinding>     

    </bindings>

 

    <behaviors>

      <serviceBehaviors>

        <behavior name="mySerBeh">                  

          <serviceMetadata httpGetUrl="mex" httpGetEnabled="true"/>                      

          <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="false"/>

        </behavior>

      </serviceBehaviors>

 

      <endpointBehaviors>

        <behavior name="webHttpendBehavior">

          <webHttp></webHttp>

        </behavior>

      </endpointBehaviors>

    </behaviors>

 

    <services>

      <service name="WcfScrverDemo.MyWcfServerMethodFace" behaviorConfiguration="mySerBeh">

        <host>

          <baseAddresses>

            <add baseAddress="http://LocalHost:7789/MySericeDemo"/>

          </baseAddresses>

        </host>

        <endpoint address="" binding="webHttpBinding" bindingConfiguration="webBinding" contract="WcfScrverDemo.IMyWcfServerMethod" behaviorConfiguration="webHttpendBehavior"></endpoint>

      </service>

    </services>

 

  </system.serviceModel>

</configuration>

在定app.config的时候要注意大小写

让这个服务跑起来吧在控件台应用程序 的Main里加上

using System.ServiceModel;
using WcfScrverDemo;

?

<br><br><br><br><br>static void Main(string[] args)

        {

             

            try

            {

                using (ServiceHost host = new ServiceHost(typeof(MyWcfServerMethodFace)))

                {

                    host.Opened += delegate

                    {

                        Console.WriteLine("server running....");

                    };

                    host.Open();

                    Console.ReadLine();

 

                }

            }

            catch (Exception ex)

            {

                Console.WriteLine(ex.ToString());

                Console.ReadLine();

            }

        }

服务就好了，运行一下吧

下面就开使定客户端了

我们也用控件台应用程序来做客户端：

建一个客户端程序WcfwebHttpClient

回为用的是webHttpBinding我们可以直接传url就ok了，不用配制app.config

很简单的在Main里加上

?

static void Main(string[] args)

        {

            try

            {

                string strPost = "小妞,给大爷笑一个,不笑,那大爷给你笑一个,我和超人唯一的区别就是我把内裤穿里边了." +

                                 "我的饭量你是知道的，而且我也不爱吃烤鸭，所以吃了四只我就吃不下去了，我就说:实在" +

                                 "不能吃了，待会儿回家还要吃饭呢。天堂这儿还有一牌子：天堂周围四百米严禁摆摊！上帝" +

                                 "坐那正抽烟呢。上帝说，必须好好招待，这么些年好容易有个说相声的上了天堂了。一巴掌" +

                                 "宽护心毛，还纹一条带鱼。《<span>金 梅</span>》里唐僧取经那会儿…… 三十多岁没结婚，北京的媒婆" +

                                 "界就轰动了！骑着脖子拉屎，拉干的我拨下去，拉稀的我擦干了，可是他，骑着脖子拉痢疾！" +

                                 "说相声讲究说学逗唱，当你有口吃就不能说相声。，比如你报时，如果你有口吃就出现这样情况" +

                                 "。现在播报北....北...北京...时.. 时....时间...七....七..七点，靠，我一看表都八点半了  ";

                byte[] buffer = Encoding.UTF8.GetBytes(strPost);

                HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://LocalHost:7789/MySericeDemo/postMostStr/" + buffer.Length);

                request.Method = "POST";

                request.ContentType = "text/plain";

 

                request.ContentLength = buffer.Length;

                Stream requestStram = request.GetRequestStream();

                requestStram.Write(buffer, 0, buffer.Length);

                requestStram.Close();

 

                Stream getStream = request.GetResponse().GetResponseStream();

 

                byte[] resultByte = new byte[200];

                getStream.Read(resultByte, 0, resultByte.Length);

 

                Console.WriteLine(Encoding.UTF8.GetString(resultByte));

            }

            catch (Exception ex)

            {

                Console.WriteLine(ex.ToString());

            }

            Console.ReadLine();

        }

　　跑一下看看什么效果吧

看一看服务有输出 吗

 

看一看客户端有没有反回

再看一下ios的代码

?

NSString *myString=@"郭：新年新气象，在这里我们代表512的全体室员向大家拜年了，新年快乐，谢谢各位的捧场，支持于：过年好郭：小孩儿们喜欢过年，都盼着过年，岁数大了就这么回事，那会儿来说穿新衣服、吃好吃的现在对我们来说没这个概念于：现在不盼着这个了郭：小时候盼着给红包，给钱，十块二十块钱，乐的跟什么似的于：那就不少啦郭：那天在寝室聊天，他们家亲戚多于：人多郭：一到春节对他来说收获的季节到了，家里人来了，亲戚来了，朋友来了，谦儿呢？于：都找我郭：呦呦呦，有长个儿了，掏出来了郭：给呀，碎钱于：我静弄点零钱了合着，还挨一句骂，您着把它连起来说成不成啊";

    NSMutableURLRequest *request=[[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:[NSString stringWithFormat: @"http://10.0.3.5:7789/MySericeDemo/postMostStr/%d",[[myString dataUsingEncoding:NSUTF8StringEncoding] length]]]];

    [request setHTTPMethod:@"POST"];

    [request setValue:@"text/plain" forHTTPHeaderField:@"Content-type"];

     

     

     

    [request setValue:[NSString stringWithFormat:@"%d",[myString length]]  forHTTPHeaderField:@"Content-length"];

     

    [request setHTTPBody:[myString dataUsingEncoding:NSUTF8StringEncoding]];

     

    [NSURLConnection connectionWithRequest:request delegate:self];

　　

 

 

好了，简单的小例子就ok了
