【小程序】通过request实现小程序与后台asp.net的数据json传输(Post协议 图文+代码)_c#_02

1、index.wxml

<view>
{{student[0].name}}
</view>
<view>
{{student[0].sex}}
</view>
<view>
{{student[0].old}}
</view>

2、index.js

// index.js
// 获取应用实例
const app = getApp()

Page({
data: {
student: [{
"name": "张三",
"old": "15",
"sex": "女"
}]
},
// 事件处理函数
onLoad() {
wx.request({
url: 'http://localhost:3954/handle/ApiPost.ashx',
method: "post",
header: {
'content-type': 'application/x-www-form-urlencoded;charset=utf-8' // 默认值 x-www-form-urlencoded;charset=utf-8 json
},
data: {
id: 666,
name: "刘德华"
},
success: res => {
var resData = res.data.replace(" ", "");
//去掉utf8编码的BOM头
resData = resData.replace(/\ufeff/g, "");
var jsonObj = JSON.parse(resData);
console.log(jsonObj);
this.setData({
student: jsonObj
})
}
})

},
})

二、ASP.net后端代码

 1、ApiPost.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ApiPost.aspx.cs" Inherits="ApiPost" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</html>

 2、ApiPost.aspx.cs

using System;
using System.Collections.Generic;

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class ApiPost : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}

}

3、ApiPost.ashx

<%@ WebHandler Language="C#" Class="ApiPost_handle" %>

4、ApiPost.cs

using System;

}

public bool IsReusable
