Question

请指导我在这段代码中找到问题，当我使用带有HTTP的url然后它工作正常但是使用HTTPS它会给出问题。我用google搜索但找不到解决方案。如果有人指导我节省我的时间，那将是值得的。谢谢

public String doRequest() {

    String serverUrl = Constants.BASE_URL + mAction;
    Log.d("usm_serverUrl",serverUrl);
    if (mParams != null) {
        serverUrl += "?" + mParams;
    }
    Log.d("usm_serverUrl",serverUrl);
    try {
        URL url = new URL(serverUrl);
        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
        conn.setRequestProperty("User-Agent", "application/json");
        conn.setRequestMethod("GET");
        if(conn.getResponseCode() == HttpsURLConnection.HTTP_OK){
            // Do normal input or output stream reading
            Log.d("usm_requestCode","Successful");
        }
        else {
            Log.d("usm_requestCode","Failed");
           // response = "FAILED"; // See documentation for more info on response handling
        }
        //HttpURLConnection conn = (HttpURLConnection) url.openConnection();


        InputStream in = new BufferedInputStream(conn.getInputStream());
        Log.d("debug", "get-url: " + serverUrl);
        String response = IOUtils.toString(in, "UTF-8");
        Log.d("debug", "get-url: " + serverUrl + "\n post-response: " + response);
        return response;
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}

我遇到以下异常：

Answer 1

要使https url连接在android中工作，请使用HttpsUrlConnection而不是HttpUrlConnection。请参阅Documentation此处

Answer 2

引用链接，它将有助于HttpsUrlConnection而不是HttpUrlConnection。 http://developer.android.com/reference/javax/net/ssl/HttpsURLConnection.html

http://www.java-samples.com/java/POST-toHTTPS-url-free-java-sample-program.htm

Https网址不起作用，但http url在android中工作正常
