Json串解析Unity（兩種解析方法）
阿新 • • 發佈：2019-02-19
朋友Json解析遇到點問題，我看了下他們伺服器給他的Json串確實有點複雜，json串裡套著json串，json裡又有陣列，數組裡又套著陣列：我耐心的幫他弄了一下，在Unity裡解析如下（解析時需要用到LitJson.dll,f放到Plugins檔案下） 
sing UnityEngine;
using System.Collections;
using LitJson;
public class NewBehaviourScript : MonoBehaviour {
// Use this for initialization
void Start () {
getScore();
}
// Update is called once per frame
void Update () {
}
public void getScore()
{//json串 string strJson = @" { ""head"": { ""senddate"": ""20160406"", ""organcode"": ""231073"", ""tradecode"": ""20100"", ""workdate"": ""20160406"", ""devicecode"": ""PADLCZ"", ""reserve"": ""1"", ""sendtime"": ""170112"", ""version"": ""1.0"" }, ""body"": { ""result"": ""0"", ""data"": [ { ""releasetime"": ""2017 -03-23 16:37:22"", ""status"": ""正常"", ""hottype"": ""最新產品"", ""medialist"": [ { ""filepath"": ""uploadFiles /uploadImgs/20161220/78c94cbd5f054f4d9570dc137332f4cd.png,uploadFiles/uploadImgs/20161219/9874efd2349a44c79caaef4b82ef02b0.png,uploadFiles/uploadImgs/20161219/bd3135171aae4fa5abad1d447f2a0198.png,uploadFiles/uploadImgs/20160723/ac53639ccaf4498b86fd51748dafb482.png"", ""newiphoneid"": """", ""productid"": ""484"", ""mediaid"": ""411"", ""filename"": ""tupian"", ""filetype"": ""IMAGE"", ""resolution"": """" } ], ""productintroduction"": "" < p>XX科技PADLCZ</p>"", ""marketingdiscourse"": "" <p>XX科技PADLCZX</p>"", ""organcode"": ""231073"", ""productid"": ""484"", ""customerpad"": """", ""organname"": ""XX科技"", ""producttype"": ""理"", ""annualreturn"": ""11"", ""productname"": ""XX科技PADLCZ"" } ], ""msg"": ""獲取產品資訊成功"" } } "; JsonData jd = JsonMapper.ToObject(strJson);//獲取Json串的資料 Debug.Log(jd.Count); Debug.Log(jd["head"].ToJson()); JsonData jd1 = JsonMapper.ToObject(jd["head"].ToJson());//獲取子json串資料 Debug.Log(jd1["senddate"].ToString()); Debug.Log(jd1["organcode"].ToString()); Debug.Log(jd1["tradecode"].ToString()); Debug.Log(jd1["workdate"].ToString()); Debug.Log(jd1["devicecode"].ToString()); JsonData jd2 = JsonMapper.ToObject(jd["body"].ToJson());//獲取子json串資料Debug.Log(jd2["result"].ToString()); JsonData jdItems = jd2["data"];//陣列 for (int i = 0; i < jdItems.Count; i++) { Debug.Log("releasetime = " + jdItems[i]["releasetime"]); Debug.Log("status = " + jdItems[i]["status"]); Debug.Log("hottype = " + jdItems[i]["hottype"]); JsonData jdItems2 = jdItems[i]["medialist"];//數組裡的陣列 for (int j = 0; j < jdItems2.Count; j++) { Debug.Log("filepath = " + jdItems2[j]["filepath"]); Debug.Log("filetype = " + jdItems2[j]["filetype"]); } Debug.Log("productintroduction = " + jdItems[i]["productintroduction"]); Debug.Log("productname = " + jdItems[i]["productname"]); } Debug.Log(jd2["msg"].ToString()); } }
最終測試解析成功
json 裡{} 雙括號表示物件，[] 中括號表示陣列，"" 雙引號內是屬性或值，: 冒號表示後者是前者的值(這個值可以是字串、數字、也可以是另一個數組或物件)
所以 {"name": "catl"} 可以理解為是一個包含name為cat的物件，而[{"name": "cat"},{"name": "dog"}]就表示包含兩個物件的陣列，當然了,也可以使用{"name":["cat","dog"]}來簡化上面一部,這是一個擁有一個name陣列的物件。
最近用unity自帶的json解析工具重新解析了一下，程式碼如下，注意的一點是{ 前是類，[前是陣列，定義的類裡面的引數名字和json串裡的名字得一致，否則會解析出錯。
