我有一个关于ssl. 我连接到https链接并从中获取json。它运行良好，但有时无法连接并从中获取json。结果是我的应用程序崩溃了。我认为它必须有一种方法来打开连接并从 https 获取 json 。

我在 LG Optimus G 中使用Android 4.1.2.

这是我的错误日志：

这是我使用的功能：

public static String readJsonFromUrl(String url) throws Exception {

    String result = "";
    HttpPost httpPost = null;
    DefaultHttpClient httpClient = null;

    httpClient = httpClient();
    httpPost = new HttpPost(url);

    HttpResponse httpResponseGet = httpClient.execute(httpPost);

    HttpEntity resEntityGet = httpResponseGet.getEntity();

    result = EntityUtils.toString(resEntityGet);

    if (result.contains("\n")) {
        result = result.replace("\n", "");
    }
    return result;
}

=> 它是在行中崩溃的：HttpResponse httpResponseGet = httpClient.execute(httpPost);

你能给我一些可以解决这个问题的解决方案吗？
