Javascript:

1.使用eval var parse_json_by_eval
                                = function(str){ return eval('('+str+')'); } var value = 1; var jsonstr = '{"name":"jifeng","company":"taobao","value":++value}';
                                var json1 = parse_json_by_eval(jsonstr); console.log(json1); console.log('value:
                                '+ value); 執行結果: { name: 'jifeng', company: 'taobao', value: 2 } value: 2 2.使用JSON.parse
                                var parse_json_by_JSON_parse = function(str){ return JSON.parse(str); } value =
                                1; var jsonstr = '{"name":"jifeng","company":"taobao"}'; var json2 = parse_json_by_JSON_parse(jsonstr);
                                console.log(json2); console.log(value); From:http://www.cnblogs.com/lengyuhong/archive/2012/01/07/2262390.html
                            

PHP:

$json_string='{"id":1,"name":"jb51","email":"admin@jb51.net","interest":["wordpress","php"]}
                                '; $obj=json_decode($json_string); echo $obj->name; //prints foo echo $obj->interest[1];
                                //prints php 

Java:

JSONObject dataJson=new JSONObject("你的Json数据“);
                                JSONObject response=dataJson.getJSONObject("response"); JSONArray data=response.getJSONArray("data");
                                JSONObject info=data.getJSONObject(0); String province=info.getString("province");
                                String city=info.getString("city"); String district=info.getString("district");
                                String address=info.getString("address"); System.out.println(province+city+district+address);

C#:

使用开源的类库Newtonsoft.Json(下载地址http://json.codeplex.com/)。下载后加入工程就能用。通常可以使用JObject,
                                JsonReader, JsonWriter处理。这种方式最通用,也最灵活,可以随时修改不爽的地方。 (1)使用JsonReader读Json字符串: [csharp]
                                view plaincopy string jsonText =@"{""input"" : ""value"",""output"" : ""result""}";
                                JsonReader reader = new JsonTextReader(newStringReader(jsonText)); while (reader.Read())
                                { Console.WriteLine(reader.TokenType + "\t\t" + reader.ValueType+ "\t\t" + reader.Value);
                                } (2)使用JsonWriter写字符串: [csharp] view plaincopy StringWriter sw = new StringWriter();
                                JsonWriter writer = new JsonTextWriter(sw); writer.WriteStartObject(); writer.WritePropertyName("input");
                                writer.WriteValue("value"); writer.WritePropertyName("output"); writer.WriteValue("result");
                                writer.WriteEndObject(); writer.Flush(); string jsonText =sw.GetStringBuilder().ToString();
                                Console.WriteLine(jsonText); (3)使用JObject读写字符串: [csharp] view plaincopy JObject
                                jo = JObject.Parse(jsonText); string[] values =jo.Properties().Select(item => item.Value.ToString()).ToArray();
                                (4)使用JsonSerializer读写对象(基于JsonWriter与JsonReader): 数组型数据 [csharp] view plaincopy
                                string jsonArrayText1 ="[{'a':'a1','b':'b1'},{'a':'a2','b':'b2'}]"; JArray ja =(JArray)JsonConvert.DeserializeObject(jsonArrayText1);
                                string ja1a =ja[1]["a"].ToString(); //或者 JObject o = (JObject)ja[1]; string oa =
                                o["a"].ToString(); 

Python:

import json data= json.loads('{"ID":
                                "2", "IP":"12.12.12.12", "Port": "3000", "Sensor_Count":"1", "Control_Count": "1",
                                "Sensors":{"Sensor_Name": "tem", "Type_Count": "1", "Types":{ "types":["temp","C"],"types":["hum","N"],}},"Controls":["LCD","Relay"]
                                }') print data['ID'] 输出结果:"2" data = json.dump(data) print data 输出结果:{"ID": "2",
                                "IP":"12.12.12.12", "Port": "3000", "Sensor_Count":"1", "Control_Count": "1", "Sensors":{"Sensor_Name":
                                "tem", "Type_Count": "1", "Types":{ "types":["temp","C"],"types":["hum","N"],}},"Controls":["LCD","Relay"]
                                }
