首先，抱歉我的英语不好！我的问题：有了这个JSONParser.java，我想连接到一个SSL安全的服务器。如何更改我的代码以使其工作？
附加：SSL证书是自签名证书！
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
public JSONParser() {}
public JSONObject getJSONFromUrl(String url, List params) {
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {sb.append(line).append("n");}
is.close();
json = sb.toString();
Log.e("JSON", json);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
return jObj;
}
}
Logcat输出（我必须审查包名）：

答案 0 :(得分：0)
由于您的Android代码而未引发SSLPeerUnverifiedExcption。当未验证对等方的身份时引发的异常。可能存在某些服务器端问题或您正在使用错误的URL。因此，您无法连接服务器。
检查这些
Android ssl: javax.net.ssl.SSLPeerUnverifiedException: No peer certificate (yet again)
Safely fixing: javax.net.ssl.SSLPeerUnverifiedException: No peer certificate
javax.net.ssl.sslpeerunverifiedexception no peer certificate
