Question

我正在使用以下代码

// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://domain.com/~path/page.php");
try 
    {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("param", value1));
        nameValuePairs.add(new BasicNameValuePair("param2", value2));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } 
    catch (Exception e)
    {
        e.printStackTrace();
    }

我认为问题是路径中文件夹上的“〜”。我无法弄清楚我必须使用什么编码来使URL有效。我之前遇到过“ã”的问题，我不得不使用某种编码将网址转换为“http://XN--SEULEITO-XZA.COM/”，但这种编码不适用于孤立的“〜”。这就是printstack输出的内容。

Answer 1

在utf-8中编码您的URL字符串

String query = URLEncoder.encode(""http://domain.com/~path/page.php"", "utf-8");
HttpPost httppost = new HttpPost(query);

Answer 2

您获得NetworkOnMainThreadException的原因是您尝试通过执行HttpRequest来锁定主线程。 Don't do that！

改为使用AsyncTask。

class GetResponse extends AsyncTask<Void, Void, HttpResponse> {

    private Exception exception;

    protected HttpResponse doInBackground(Void... params) {
        // Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://domain.com/~path/page.php");
        try
        {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("param", value1));
            nameValuePairs.add(new BasicNameValuePair("param2", value2));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);
            return response;
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }

    protected void onPostExecute(HttpResponse response) {

    }
}

没关系，这个太空头在上个星期五关闭了设备的wifi，忘记了它。

在Android和＆＃34;〜＆＃34;上的Http请求在路上
