HTTP 请求无响应

Question

i have written an android app which post data to my database. The app should access an webservice which post the data to the database. the webservice works fine. ive testet it with my browser, he is already on the server. now i want my app to execute the webservice. but that doesnt work. My debugger doesnt work too so im not able to debug. here is my code to for accessing the webservice. any ideas??

public class PostBlog extends AsyncTask<String, Void, String> {
String BlogURL;

public PostBlog(String insertBlogURL) {
    BlogURL = insertBlogURL;
}

@Override
protected String doInBackground(String... params) {
    postBlogData(BlogURL);
    return null;
}

public void postBlogData(String url) {

    String result = "";
    //the year data to send
    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("year", "1980"));

    //http post
    try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(url);
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        InputStream is = entity.getContent();
        BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();

        result = sb.toString();
    } catch (Exception e) {

        //(TextView)rootView.findViewById(R.id.question)
        Log.e("log_tag", "Error converting result " + e.toString());
    }


}

}

The Class is called from my main Activity by

new PostBlog(insertBlogURL).execute("");

Is there another easier way to execute my ".jsp?asdd=sdsd" file on the server?

Thanks for your ideas.

Answer 1

Instead of doing :

new PostBlog(insertBlogURL).execute("");

Change your constructor and retrieve the url from the doInBackground method, by doing params[0]

Then initiate the download like this

PostBlog blogPoster = new PostBlog();
try {
    blogPoster.execute(insertBlogURL);
} catch (InterruptedException e) {} catch (ExecutionException e) {}

I should say this is a modified snippet of code from my own project, so it might not work exactly the way you expect.
