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 =htt​​p://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Andr​​oid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!

<%@ ServiceHost Language="C#" Debug="true" Service="WcfServiceAndroid.Service1"%>
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)
