FileNotFoundException 尝试使用 HttpURLConnection 将 JSON 发送到 .NET Web 服务

Question

我正在尝试使用以下代码从HttpURLConnection 解析来自InputStream 的响应。尝试获取InputStream 时出现错误。我只是想获得响应以检查是否网络服务调用工作OK。

     static final String SOAP_ACTION="http://888topup.com/ImageProcess.svc/UploadImage"; 
    java.net.URL url=null;
    try {
        url = new java.net.URL(SOAP_ACTION);
    } catch (MalformedURLException e) {
        Log.e(TAG, "Bad URL",e);
    }
    JSONObject obj=new JSONObject();
    try {
        obj.put("Vaue", value);
    } catch (JSONException e) {
        Log.e(TAG, "Create JSONObjerct throws an error");
    }
    HttpURLConnection urlConnection = null;
    try {
        urlConnection = (HttpURLConnection)url.openConnection();
    } catch (IOException e1) {
        Log.e(TAG,"Error opening connection",e1);
    }
    urlConnection.setDoOutput(true);
    urlConnection.setDoInput(true);
    try {
        urlConnection.setRequestMethod("POST");
        urlConnection.setRequestProperty("Accept", "*/*");
        urlConnection.addRequestProperty("Accept-Encoding", "gzip deflate sdch");
        urlConnection.setRequestProperty("Content-Type","application/json");
    } catch (ProtocolException e) {
        Log.e(TAG,"Error setting header",e);
    }
    try {
        OutputStream os=urlConnection.getOutputStream();
        BufferedOutputStream bos=new BufferedOutputStream(os);
        byte[] data=obj.toString().getBytes();
        bos.write(data);
        InputStream is=urlConnection.getInputStream();
        BufferedReader br=new BufferedReader(new InputStreamReader(is));
        String response;
        response=br.readLine();

        Log.d(TAG, "Response: "+response);
        bos.close();
        br.close();
        is.close();
        urlConnection.disconnect();
    } catch (IOException e) {
        Log.e(TAG,"Error peforming read-write operations",e);
    }

这是Logcat 条目，说明我尝试运行此代码时发生的情况：

  MainActivity(9628): Error peforming read-write operations
  MainActivity(9628): java.io.FileNotFoundException: http://888topup.com/ImageProcess.svc/UploadImage
  MainActivity(9628):   at libcore.net.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:186)
  MainActivity(8989):   at com.example.imageuploadtest.MainActivity.sendStringToServiceUsingRest(MainActivity.java:184)
  MainActivity(8989):   at com.example.imageuploadtest.MainActivity.access$0(MainActivity.java:149)
  MainActivity(8989):   at com.example.imageuploadtest.MainActivity$1$1.run(MainActivity.java:66)

编辑：

WSDL中指定的操作：

<wsdl:operation name="UploadImage">
<wsdl:input wsaw:Action="http://tempuri.org/IImageProcess/UploadImage"   message="tns:IImageProcess_UploadImage_InputMessage"/>
<wsdl:output wsaw:Action="http://tempuri.org/IImageProcess/UploadImageResponse" message="tns:IImageProcess_UploadImage_OutputMessage"/>
</wsdl:operation>

在将数据写入OutputStream 之前添加urlConnection.connect() 也不起作用。

编辑：使用 URL(SOAP_ACTION) 并传递来自 Sencha-Touch 的 jsondata 作品，供其他测试过的人使用。

尝试将 JSONObject 作为字符串而不是字节数据传递。也不起作用？

Answer 1

我所做的有一些错误，首先我将错误的参数 Vaue 而不是 Value 传递给服务。

   JSONObject obj=new JSONObject();
    try {
        String value_key="Value";
        obj.put(value_key, value);
        Log.d(TAG,obj.toString());
    } catch (JSONException e) {
        Log.e(TAG, "Create JSONObjerct throws an error");
    }

其次，我试图在未发送响应时解析响应。因此，我将获取InputStream 的代码替换为以下代码：

 int response=urlConnection.getResponseCode();

完整的代码在这里：

java.net.URL url=null;
    try {
        url = new java.net.URL(SOAP_ACTION);
    } catch (MalformedURLException e) {
        Log.e(TAG, "Bad URL",e);
    }
    JSONObject obj=new JSONObject();
    try {
        String value_key="Value";
        obj.put(value_key, value);
        Log.d(TAG,obj.toString());
    } catch (JSONException e) {
        Log.e(TAG, "Create JSONObjerct throws an error");
    }
    HttpURLConnection urlConnection = null;
    try {
        urlConnection = (HttpURLConnection)url.openConnection();
    } catch (IOException e1) {
        Log.e(TAG,"Error opening connection",e1);
    }
    urlConnection.setDoOutput(true);
    try {
        urlConnection.setRequestMethod("POST");
        urlConnection.setRequestProperty("Accept", "*/*");
        //urlConnection.addRequestProperty("Accept-Encoding", "gzip deflate sdch");
        urlConnection.setRequestProperty("Content-Type","application/json");
    } catch (ProtocolException e) {
        Log.e(TAG,"Error setting header",e);
    }
    try {
        urlConnection.connect();
        DataOutputStream dos=new DataOutputStream(urlConnection.getOutputStream());
        dos.write(obj.toString().getBytes());
        int response=urlConnection.getResponseCode();
        Log.d(TAG, "Response code: "+response);
        urlConnection.disconnect();
    } catch (IOException e) {
        Log.e(TAG,"Error peforming read-write operations",e);
    } 

最后我用它把数据作为二进制数据发送到网络服务：

  DataOutputStream dos=new DataOutputStream(urlConnection.getOutputStream());
    dos.write(obj.toString().getBytes());
