我一直试图解决这个问题几个小时了.我已经找到了答案,但我找不到答案.我以前从未打扰过这个问题,这是我第一次提出问题.基本上我正在做的是为了组织目的打破我的编码.下面的代码片段工作得很好,但是当我把它拿到另一个类时,urlConnect(); 连接就好了.我在下面标记了它.

public String downloadUrl(String strUrl) throws IOException{
    String data = "";
    InputStream iStream = null;
    HttpURLConnection urlConnection = null;

    try{
        URL url = new URL(strUrl);
        String line = "";

        // Creating an http connection to communicate with url 
        urlConnection = (HttpURLConnection) url.openConnection();

        /* Connecting to url */
        urlConnection.connect(); <-------------------------works in this snippet

        /* Reading data from url */
        iStream = urlConnection.getInputStream();
        BufferedReader br = new BufferedReader(new InputStreamReader(iStream));
        StringBuffer sb  = new StringBuffer();

        while((line = br.readLine()) != null){
            sb.append(line);
        } …
