如何使用android在json中传递多个参数列表，语法问题

我必须传递一个带有方法和多个参数的json对象

对象必须具有此窗体

{"method":"startSession","params":"["email" "testmail@test.it", "password" "1234", "stayLogged" "1", "idClient" "IPHONE"]"}

{"method":"startSession","params":"["email" "testmail@test.it", "password" "1234", "stayLogged" "1", "idClient" "IPHONE"]"}

我在android中发送此对象的代码是

HttpPost httppost = new HttpPost(BASE_URI);

           JSONObject json = new JSONObject(); 

            String email="testmail@test.it";
            String emailRic="email"+" "+"\""+email+"\"";
            String password="1234";
            String passwordRic="password"+" "+"\""+password+"\"";
            String stayLogged="1";
            String stayLoggedRic="stayLogged"+" "+"\""+stayLogged+"\"";
            String idClient="ANDROID";
            String idClientRic="idClient"+" "+"\""+idClient+"\"";

            try {
                List<String> accessParameters=new ArrayList<String>();
                accessParameters.add(emailRic);
                accessParameters.add(passwordRic);
                accessParameters.add(stayLoggedRic);
                accessParameters.add(idClientRic);
                String par=accessParameters.toString();

                json.put("method", "startSession");
                json.put("params", par);                  

                JSONArray postjson=new JSONArray(); 
                postjson.put(json); 
                httppost.setHeader("json",json.toString());
                httppost.getParams().setParameter("jsonpost",postjson); 
                System.out.print(json); 
                HttpResponse response = mClient.execute(httppost); 

                if(response != null){
                    InputStream is = response.getEntity().getContent();

                    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
                    StringBuilder sb = new StringBuilder();
                    System.out.println("the answer is:\n"+sb);
                    String line = null;

                try {
                        while ((line = reader.readLine()) != null) {
                        sb.append(line + "\n");
                        }

                    } catch (IOException e) {
                        e.printStackTrace();
                    } finally {
                        try {
                            is.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
               // text = sb.toString();
                }
               // tv.setText(text);

            }catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
            } catch (IOException e) {
                // TODO Auto-generated catch block
            }

（我在调试器中看到了这一点）

如果我试图从代码段中删除值\“

   String email="testmail@test.it";
            String emailRic="email"+" "+"\""+email+"\"";
            String password="1234";
            String passwordRic="password"+" "+"\""+password+"\"";
            String stayLogged="1";
            String stayLoggedRic="stayLogged"+" "+"\""+stayLogged+"\"";
            String idClient="ANDROID";
            String idClientRic="idClient"+" "+"\""+idClient+"\"";

发送的对象采用以下形式

  {"method":"startSession","params":"[email testmail@test.it, password 1234, restaConnesso 1, idClient IPHONE]"}

我如何将json与exacty一起发送到sintax？？？

DefaultHttpClient-httpclient=newdefaulthttpclient（）；
HttpPost HttpPost=新的HttpPost（url）；
//首先，从所需的json作为一个整体声明并创建一个json对象。
/*如何创建Json*/
JSONObject jObjectData=新的JSONObject（）；
//使用Facebook数据创建Json对象
jObjectData.put（“方法”、“开始会话”）；
ArrayList=新建ArrayList（）；
列表。添加（“电子邮件”）；
列表。添加（“testmail@test.it");
等
JSONArray jsArray=新JSONArray（列表）；
jObjectData.put（“params”，jsArray）；
StringEntity StringEntity=新的StringEntity（jObjectData.toString（））；
httpost.setEntity（stringEntity）；
setHeader（“接受”、“应用程序/json”）；
setHeader（“内容类型”、“应用程序/json”）；
ResponseHandler ResponseHandler=新BasicResponseHandler（）；
response=httpclient.execute（httpost，responseHandler）；

我不确定，但问题不在于您试图发送一个数组而不是发送一个字符串吗

原件：

   {"method":"startSession",
    "params":"["email" "testmail@test.it", "password" "1234", "stayLogged" "1", "idClient" "IPHONE"]"}

应该是这样的（数组周围没有引号）：

编辑：实际上我认为您实际上想要一个嵌套对象：

   {"method":"startSession",
    "params": { "email": "testmail@test.it", 
                "password": "1234", 
                "stayLogged": "1", 
                "idClient": "IPHONE"
               }
   }

没有

编辑#2：你应该看看如何正确使用JSONArray和JSONObject，有一些很好的例子。

谢谢你的回答，但我不明白如何准确地使用你发布的代码。你能告诉我更多吗？？？我已经尝试过了，但不起作用…如果我尝试在JSONArray=new之后打印字符串JSONArray（列表）；jObjectData.put（“params”，jsArray）；placing String out=jsArray.toString（）；System.out.print（out）；不打印任何东西是的，对，我想要一个嵌套对象。但我不知道如何为这个json{“方法”：“startSession”，“params”：{“email”：testmail@test.it", "密码“：“1234”，“stayLogged:“1”，“idClient:“IPHONE”}”

/* Create Json object for set parameter*/
JSONObject jObjectData = new JSONObject();


// set your first parameter name
jObjectData.put("parameter1", "startSession");

ArrayList<JSONObject> list = new ArrayList<JSONObject>();
// for 1 parameter   
JSONObject jObjectData1 = new JSONObject();
jObjectData1.put("email","testmail@test.it");
jObjectData1.put("password","1234");
jObjectData1.put("stayLogged","1");
jObjectData1.put("idClient","IPHONE");
list.add(jObjectData1);

JSONArray jsArray = new JSONArray(list);

// set your second parameter has more value
jObjectData.put("parameter2", jsArray);

   {"method":"startSession",
    "params": ["email" "testmail@test.it", "password" "1234", "stayLogged" "1", "idClient" "IPHONE"]}

   {"method":"startSession",
    "params": { "email": "testmail@test.it", 
                "password": "1234", 
                "stayLogged": "1", 
                "idClient": "IPHONE"
               }
   }

/* Create Json object for set parameter*/
JSONObject jObjectData = new JSONObject();


// set your first parameter name
jObjectData.put("parameter1", "startSession");

ArrayList<JSONObject> list = new ArrayList<JSONObject>();
// for 1 parameter   
JSONObject jObjectData1 = new JSONObject();
jObjectData1.put("email","testmail@test.it");
jObjectData1.put("password","1234");
jObjectData1.put("stayLogged","1");
jObjectData1.put("idClient","IPHONE");
list.add(jObjectData1);

JSONArray jsArray = new JSONArray(list);

// set your second parameter has more value
jObjectData.put("parameter2", jsArray);

{"parameter1":"startSession",
"parameter2": [{ "email": "testmail@test.it", 
            "password": "1234", 
            "stayLogged": "1", 
            "idClient": "IPHONE"
           }]
}
