Question

我有一个Android应用程序，它在服务器上调用一些php脚本，并通过使用＆＃34; normal＆＃34;来接收json消息作为响应。 HTTP连接如：

static JSONObject jObj = null;
static String json = "";

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();

BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
    sb.append(line + "\n");

}
is.close();
json = sb.toString();
jObj = new JSONObject(json);
//code for parse jObj Object

现在我需要在使用ssl进行加密数据的新服务器上传输整个服务器。在开始服务器迁移之前，我需要知道如何修改我的android源代码，以便通过https使用它。只需要用https修改脚本地址（和HttpPost自动管理所有https阶段），或者我需要做其他实质性的修改？

使用以下代码使用post方法将json数据发送到服务器。

try {
            HttpClient httpClient = new DefaultHttpClient();
            JSONObject object = new JSONObject();
            object.put("Username", "testUser@123");
            object.put("Password", "testPassword@123");
            JSONObject jsonObject = new JSONObject();
            jsonObject.put("Authentication", object);
            jsonObject.put("RequestType", 4);
            HttpPost postMethod = new HttpPost("your_url");
            postMethod.setEntity(new StringEntity(jsonObject.toString()));
            postMethod.setHeader("Accept", "application/json");
            postMethod.setHeader("Content-type", "application/json");
            HttpResponse response = httpClient.execute(postMethod);
            HttpEntity entity = response.getEntity();
            String response_value = EntityUtils.toString(entity).toString();
        } catch (Exception e) {
            e.printStackTrace();
        }

如果您从服务器获得响应，则必须尝试此操作。

static JSONObject jObj = null;
        static String json = "";
        StringBuilder builder =new StringBuilder();
        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();
         while(is.read()!=-1){
             builder.append((char)is.read());
         }

        is.close();
        json = builder.toString();
        jObj = new JSONObject(json);

通过https发送和接收json消息
