wcf webHttpBinding Post

wcf webHttpBinding Post 大數據量提交 ios c＃客戶端

 

一直在爲安卓和蘋果寫服務，剛開始的時候全用的Get請求用url傳全部的參數，因爲url長度的限制大的數據量

沒法傳到服務器，提交圖片什麼的就更不用說了，後來用的POST請求，記錄一下，作了一個很簡單的小例子：

c#源代碼提供你們下載 10Solution4.rar

ios代碼 IOSHttpPostDemo.rar

 開始作吧！

1建一個空工程Solution4，添加一個類庫WcfSerDemo引入

System.ServiceModel  和System.ServiceModel.Web兩個類庫

建一個接口IMyWcfServerMethod

?

[ServiceContract] public  interface  IMyWcfServerMethod {　　　　      [OperationContract, WebInvoke(Method = "POST" , UriTemplate = "postMostStr/{streamLength}" , BodyStyle = WebMessageBodyStyle.Bare)]      string  postMostStr( string  streamLength, Stream getStream);        //實驗一下接收      [OperationContract, WebInvoke( Method= "GET" , UriTemplate = "postText" )]      string  postText(); }

咱們只用 postMostStr這個方法它是以POST形式接收的Url只要一個參數就是傳過來的byte的長度

那個Stream類型的臺數就是Post過來的數據

建一個類實現這個接口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寫到resultByte                  Console.WriteLine(Encoding.UTF8.GetString(resultByte)); //把收到的數據輸出到控制檯                }              catch  (Exception ex)              {                  Console.WriteLine(ex.ToString());              }              Console.WriteLine( "success!" );              return  "success!" ;          }            public  string  postText()          {              Console.WriteLine( "text!" );              return  "text success" ;                       }      }

好了契約就寫好了，宿主程序就用控制檯程序

加一個控制程序

引入System.ServiceModel 和 WcfSerDemo

配製App.config

?

<?xml version= "1.0"  encoding= "utf-8"  ?> <configuration>    <system.serviceModel>      <bindings>        <webHttpBinding><!--這個是接收大數據加的-->          <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的時候要注意大小寫

讓這個服務跑起來吧在控件臺應用程序 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();              }          }

服務就行了，運行一下吧

下面就開使定客戶端了

咱們也用控件臺應用程序來作客戶端：

建一個客戶端程序WcfwebHttpClient

回爲用的是webHttpBinding咱們能夠直接傳url就ok了，不用配製app.config

很簡單的在Main里加上

?

static  void  Main( string [] args)          {              try              {                  string  strPost = "小妞,給大爺笑一個,不笑,那大爺給你笑一個,我和超人惟一的區別就是我把內褲穿裏邊了."  +                                   "個人飯量你是知道的，並且我也不愛吃烤鴨，因此吃了四隻我就吃不下去了，我就說:實在"  +                                   "不能吃了，待會兒回家還要吃飯呢。天堂這兒還有一牌子：天堂周圍四百米嚴禁擺攤！上帝"  +                                   "坐那正抽菸呢。上帝說，必須好好招待，這麼些年好容易有個說相聲的上了天堂了。一巴掌"  +                                   "寬護心毛，還紋一條帶魚。《<span>金 梅</span>》裏唐僧取經那會兒…… 三十多歲沒結婚，北京的媒婆"  +                                   "界就轟動了！騎着脖子拉屎，拉乾的我撥下去，拉稀的我擦乾了，但是他，騎着脖子拉痢疾！"  +                                   "說相聲講究說學逗唱，當你有口吃就不能說相聲。，好比你報時，若是你有口吃就出現這樣狀況"  +                                   "。如今播報北....北...北京...時.. 時....時間...七....七..七點，靠，我一看錶都八點半了  " ;                  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();          }

　　跑一下看看什麼效果吧

看一看服務有輸出 嗎

 

看一看客戶端有沒有反回

再看一下ios的代碼

?

NSString *myString= @"郭：新年新氣象，在這裏咱們表明512的全體室員向你們拜年了，新年快樂，謝謝各位的捧場，支持於：過年好郭：小孩兒們喜歡過年，都盼着過年，歲數大了就這麼回事，那會兒來講穿新衣服、吃好吃的如今對咱們來講沒這個概念於：如今不盼着這個了郭：小時候盼着給紅包，給錢，十塊二十塊錢，樂的跟什麼似的於：那就很多啦郭：那天在寢室聊天，他們家親戚多於：人多郭：一到春節對他來講收穫的季節到了，家裏人來了，親戚來了，朋友來了，謙兒呢？於：都找我郭：呦呦呦，有長個兒了，掏出來了郭：給呀，碎錢於：我靜弄點零錢了合着，還挨一句罵，您着把它連起來講成不成啊" ;      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，簡單的小例子就ok了
