android - 异步任务中的 HTTP GET 不起作用

Question

我从 HTTPPOST 收到响应，从中获取一个子字符串，即 URL，然后对其执行 HTTPGET，但我无法获得任何响应。关于问题可能是什么的任何意见？

 String pkmspogout1 = result.substring(result.indexOf(",")+1,result.length());
                        Log.i("Lpkmspogout1 ", pkmspogout1);


                    HttpClient httpclient4 = new DefaultHttpClient();

                    HttpResponse logoutresponse  ;
                    try {
                        HttpGet httpget = new HttpGet(pkmspogout1);

                        logoutresponse = httpclient4.execute(httpget);
                        BufferedReader in2 = new BufferedReader(new InputStreamReader(logoutresponse.getEntity().getContent()));

                        StringBuffer sb2 = new StringBuffer("");

                        String line2 = "";
                        String NL2 = System.getProperty("line.separator");
                         while ((line2 = in2.readLine()) != null) {
                            sb2.append(line + NL2);

                        }
                        in2.close();


                        String pkmslogout5 = sb2.toString();
                        Log.i("logoutresponse from pkms", pkmslogout5+"");
                    } catch (Exception e) {}

pkmspogout1 是正确的 url 吗？此外，您应该确保执行以下操作以查看任何错误:

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

尝试将 url 编码如下:

String[] url = pkmspogout1.split("com"); //Or whatever is the last part of the main url. 
                         //The letter "." means any character btw as it is a regular expression.
String finalUrl = url[0];
for(int i=0; i<url.length; i++){
     finalUrl += URLEncoder.encode(url[i],"UTF-8");
}

老实说有点粗糙....为什么在服务器端形成时最好对其进行编码。

你可以试试:

pkmspogout1 = pkmspogout1.replace("http://","");
pkmspogout1 = URLEncoder.encode(pkmspogout1);
pkmspogout1 = "http://"+pkmspogout1;

查看是否只有“http://”破坏了您的网址。我仍然认为 url 才是最重要的问题，因为你告诉我硬编码它工作正常。
