C＃/ Java的 - 从消费Android模拟器WCF服务 [英] C#/Java - Consuming WCF Service from Android emulator
本文介绍了C＃/ Java的 - 从消费Android模拟器WCF服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想学习Android的如何与WCF（C＃）服务交互。我已经通过关于一样的，在这里让很多帖子了。但是，我无法找到一个明确的答案的问题。每一个机构发布了自己的方法，这是混淆了我。
我创建了一个演示服务，它只是返回的字符串Hello World！
公共字符串的HelloWorld（）
{
返回（的Hello World！）;
}
我已经定义了服务合同为：
[OperationContract的]
[XmlSerializerFormat（风格= OperationFormatStyle.Document，使用= OperationFormatUse.Literal）
[WebGet（BodyStyle = WebMessageBodyStyle.Wrapped，RequestFormat = WebMessageFormat.Xml，
ResponseFormat = WebMessageFormat.Xml，UriTemplate =/ GetMessage函数）]
字符串的HelloWorld（）;
该服务工作正常在的http：//本地主机：32444 / Service1.svc
现在，在Android我试图消耗与下列code的服务。
公共类MainActivity延伸活动{
/ **
*当第一次创建活动调用。
* / 私人最终静态字符串SERVICE_URI =http://10.0.2.2:32444/Service1.svc;
TextView中的TextView;
按钮btnShow; @覆盖
公共无效的onCreate（捆绑savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.main）; TextView的=（的TextView）findViewById（R.id.textView）;
btnShow =（按钮）findViewById（R.id.btnShow）; btnShow.setOnClickListener（新View.OnClickListener（）{ @覆盖
公共无效的onClick（查看为arg0）{ 尝试{ DefaultHttpClient的HttpClient =新DefaultHttpClient（）;
HTTPGET请求=新HTTPGET（SERVICE_URI +/ GetMessage函数）; request.setHeader（接受，应用程序/ XML）;
request.setHeader（内容类型，应用程序/ XML）; HTT presponse响应= httpClient.execute（请求）; HttpEntity responseEntity = response.getEntity（）;
字符串输出= EntityUtils.toString（responseEntity）; //Toast.makeText（getApplicationContext（），输出Toast.LENGTH_SHORT）.show（）;
textView.setText（输出）;
}赶上（例外五）{
e.printStackTrace（）;
Toast.makeText（getApplicationContext（），e.getMessage（），Toast.LENGTH_SHORT）.show（）;
}
}
}）;
}
}
仿真器显示没有输出。我检查了使用吐司消息和回报null.The错误是由于HTTP1.1 / 400错误的请求，这是我碰到的同时调试。
有人可以请指导我这个？此外，如果方法/概念是错误的，请指出我我的错误，并提供了一个解释。
感谢所有提前！

解决方案
而不是你应该使用本地主机10.0.2.2。因为localhost您的计算机。这是你的Android模拟器。如果你仍然无法连接，尝试编辑您的IIS配置。
在您的用户文档> IISEx preSS>对ApplicationHost.config编辑WCF服务项目的绑定信息。它是这样的：bindingInformation =：21422：本地主机
你应该删除本地主机，应该是这样的：bindingInformation =的：21422：
要清楚你的连接地址是http：// 10.0.2.2:port/svcfile /...
我希望它的工作原理
编辑：您必须运行具有管理员权限的Visual Studio（以管理员身份运行）
I'm trying to learn how Android interacts with WCF (C#) service. I have gone through a lot of posts regarding the same, here at SO. However, I couldn't find a definite answer to the problem. Every body has posted their own approach and it is confusing me.
I have created a demo service which just returns the string "Hello World!!".
public string HelloWorld()
{
return ("Hello World!");
}
I have defined the service contract as:
[OperationContract]
[XmlSerializerFormat(Style = OperationFormatStyle.Document, Use = OperationFormatUse.Literal)]
[WebGet(BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Xml,
ResponseFormat = WebMessageFormat.Xml, UriTemplate = "/GetMessage")]
string HelloWorld();
The service is working fine on http://localhost:32444/Service1.svc.
Now, from Android I'm trying to consume the service with the following code.
public class MainActivity extends Activity {
/**
* Called when the activity is first created.
*/
private final static String SERVICE_URI = "http://10.0.2.2:32444/Service1.svc";
TextView textView;
Button btnShow;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textView = (TextView) findViewById(R.id.textView);
btnShow = (Button) findViewById(R.id.btnShow);
btnShow.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View arg0){
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet request = new HttpGet(SERVICE_URI + "/GetMessage");
request.setHeader("Accept", "application/xml");
request.setHeader("Content-type", "application/xml");
HttpResponse response = httpClient.execute(request);
HttpEntity responseEntity = response.getEntity();
String output = EntityUtils.toString(responseEntity);
//Toast.makeText(getApplicationContext(), output, Toast.LENGTH_SHORT).show();
textView.setText(output);
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
});
}
}
The emulator shows no output. I checked using Toast message and the return is null.The error is due to "HTTP1.1/400 Bad Request", which I came across while debugging.
Can somebody please guide me with this? Also, if the approach/concept is wrong please point to me my mistake and provide an explanation.
Thanking all in advance!

解决方案
instead of localhost you should use 10.0.2.2 . Because localhost is not your computer. It is your android emulator. And if you still can't connect, try to edit your iis config.
in your user Documents > IISExpress > applicationhost.config edit your wcf service projects binding information. it is something like this : bindingInformation=":21422:localhost" and you should delete localhost and should be something like this : bindingInformation=":21422:"
to be clear your connection address is http:// 10.0.2.2:port/svcfile/...
I hope it works
edit: you have to run visual studio with administrator privileges (Run as administrator)
