wcf webHttpBinding Post
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
