本文介绍了WCF主机和Android客户端，Ksoap2 http请求失败，http状态：404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


你好我检查&重新检查我的KSoap2参数：Namespace，Method，SoapAction和URL everythings看起来没问题，但我总是得到错误404



我基于microsoft示例创建的WFC服务：   https://docs.microsoft.com/en-us/dotnet/framework/wcf/getting-started-tutorial



Using示例C＃Client是s uccess调用WFC服务，从浏览器打开以获取xml信息成功，同时使用WFC Test Client也成功。



我已经为此打开了tcp输入/输出端口。在网上提供了一些提示后我也将WSHttpBinding更改为我的主机中的BasicHttpBinding。但是当我尝试使用Android Studio 3.0进行调用时KSoap2 ver3.6.2它总是得到404



以下是我从浏览中复制的xml数据：

此XML文件似乎没有任何关联的样式信息$ b文件树如下所示。

这是我在Android Studio中的代码： 



私有类Soapcall扩展了AsyncTask< String，Object，String> {
 
 public static final String NAMESPACE =" http://tempuri.org/" ;; 
 public static final String METHOD_NAME =" GetJunkData" ;; 
 public static final String SOAPACTION = 
" http://tempuri.org/ICalculator/GetJunkData" ;; 
 public static final String URI = 
" http：//192.168.1.201：8000 / WCFTRIAL？wsdl" ;; 
 public static final int Timeout = 3000; 
字符串响应; 
 
 @Override 
 protected String doInBackground（String ... strings）{
 SoapObject request = new SoapObject（NAMESPACE，METHOD_NAME）; 
 SoapSerializationEnvelope envelope = new 
 SoapSerializationEnvelope（SoapEnvelope.VER11）; 
 envelope.dotNet = true; 
 envelope.setOutputSoapObject（request）; 
 HttpTransportSE transport = new HttpTransportSE（URI，Timeout）; 
 
 try {
 transport.call（SOAPACTION，envelope）; //<  -  ERROR OCCUR HERE 
 response =（String）envelope.getResponse（）; 
} catch（例外e）{
 e.printStackTrace（）; 
 Log.e（" Error"，e.getMessage（）。toString（））; 
} 
返回回复; 
}





总结我的

   NAMESPACE   =  " http：//tempuri.org/"  ;   
 METHOD_NAME   =  " GetJunkData"  ;   
 SOAPACTION   =    " http://tempuri.org/ICalculator/GetJunkData"  ;   
 URL   =  " http：//192.168.1.201：8000 / WCFTRIAL？wsdl"  ;



我很确定这是基于WSDL的正确，请点亮我如何纠正这个404错误。

解决方案

我建议您使用Fiddler并在获得404时查看原始HTML流量。

Hi Im had check & recheck my KSoap2 param : Namespace, Method, SoapAction, and URL everythings looks ok but I always got error 404

The WFC service I create based on microsoft examples: https://docs.microsoft.com/en-us/dotnet/framework/wcf/getting-started-tutorial

Using the examples C# Client was success to call the WFC services, opening from browser to get xml info was success, also using WFC Test Client also success.

I already open tcp in/out port 8000 for this. Following some hints on the web Im also had change WSHttpBinding into BasicHttpBinding in my host. But when I tried to call from Android Studio 3.0 using KSoap2 ver3.6.2 its always got 404

below is the xml data I copied from browse :

This XML file does not appear to have any style information associated 
with it. The document tree is shown below.

and this is my code in Android Studio:

private class Soapcall extends AsyncTask<String,Object,String>{

    public static final String NAMESPACE ="http://tempuri.org/";
    public static final String METHOD_NAME ="GetJunkData";
    public static final String SOAPACTION = 
         "http://tempuri.org/ICalculator/GetJunkData";
    public static final String URI =
         "http://192.168.1.201:8000/WCFTRIAL?wsdl";
    public static final int Timeout=3000;
    String response;

    @Override
    protected String doInBackground(String... strings) {
        SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME);
        SoapSerializationEnvelope envelope = new 
            SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet=true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE transport = new HttpTransportSE(URI,Timeout);

        try{
            transport.call(SOAPACTION,envelope); //<--ERROR OCCUR HERE
            response = (String)envelope.getResponse();
        }catch (Exception e){
            e.printStackTrace();
            Log.e("Error",e.getMessage().toString());
        }
        return response;
    }


To summary my

NAMESPACE ="http://tempuri.org/";
METHOD_NAME ="GetJunkData";
SOAPACTION = "http://tempuri.org/ICalculator/GetJunkData";
URL ="http://192.168.1.201:8000/WCFTRIAL?wsdl";

Im pretty sure this is correct based on the WSDL, please en-light me how Im to correct this 404 error.

解决方案

I suggest that you use Fiddler and look at the raw HTML traffic when you get the 404.
