一:小程序端:java
wxml中代碼:json
<!--index.wxml--> <view> <view> <button bindtap="onShow"> 調接口 </button> </view> </view>
js中代碼:小程序
//index.js //獲取應用實例 const app = getApp() Page({ onShow:function(){ console.log('123456') let newDate={ a:JSON.stringify([{a:1,b:2},{a:3,b:2}]) } wx.request({ url: 'http://10.0.1.183:8080/aone_sg/wx/aaa.action', method:'POST', data: {a:newDate.a}, header:{ 'Content-Type':'application/x-www-form-urlencoded;charset=utf-8' }, success(res){ console.log(res) } }) } })
二:Java後端:後端
調用的接口代碼:數組
private String a;//入參數組轉成的json格式的字符串 @Action(value="aaa") public void aaa() throws IOException{ System.out.println("進入"); System.out.println(a); TestDemo.bbbb(a); } //get/set.......
入參Json字符串(數組)在bean中的工具類裏轉化成對應的對象集合:app
package com.aone.foottalk.common; import java.util.List; import net.sf.json.JSONArray; public class TestDemo { private String a; private String b; public String getA() { return a; } public void setA(String a) { this.a = a; } public String getB() { return b; } public void setB(String b) { this.b = b; } @SuppressWarnings("unchecked") public static void bbbb(String a){ //轉對象集合 JSONArray json = JSONArray.fromObject(a); List<TestDemo> list = (List<TestDemo>)JSONArray.toCollection(json, TestDemo.class); list.forEach(f->{ System.out.println(f.getA()+"***"+f.getB()); }); } }
小程序傳的數組此時就變成後端拿到的List對象集合了須要注意的是:先後端須要約定好數組中傳的字段就是實體類中須要轉化的字段ide
