我想解析从响应 InputStream 从 HttpURLConnection 使用以下代码。试图获取时出现错误 InputStream 。我只想要得到的响应来检查是否 web servcice 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);
    }

这里是 Logcat 条目，当我试图运行此代码时，发生了什么事：

  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：

在WSDL中指定操作：

<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>

添加 urlConnection.connect() 之前写入数据到 OutputStream 不会也不起作用。

编辑: 使用 URL(SOAP_ACTION) 和 jsondata 工程从传递煎茶触摸别人的人对其进行测试。

尝试将 JSONObject 作为字符串传递而不字节的数据。做了也不起作用吗？

有几个错误是在做什么，首先我传递错误的参数 Vaue 而不是 Value 的服务。

   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");
    }

第二，我想解析响应时不正在发送响应。所以，我替换代码来获取 InputStream 用下面的代码：

 int response=urlConnection.getResponseCode();

这里是整个代码：

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);
    } 

我终于用这个来将数据发送到作为二进制数据的 web 服务：

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