一:前期准备
要想实现微信登陆,首先必须注册开发者账号。
- 登录微信开放平台,添加移动应用并提交审核,审核通过后可获取应用ID(AppID),AppSecret等信息
- 在应用详情中
申请开通
微信登录功能,根据页面提示填写资料,提交审核 - 申请审核通过后即可打包使用微信授权登录功能
二:实现思路
1.app端请求调用微信登陆,用户登陆授权之后会返回一个code,通过这个code加上appid和 appSecret和可以得到access_token和openid等信息,通过access_token和openid 我们就可以去查询到用户基本登陆信息了。
三:具体实现
1.配置
在Hbulidx工具里打开uniapp项目,找到
manifest.json文件,在“App模块配置”项的“OAuth(登录鉴权)”下,勾选“微信登录”:
- appid
微信开放平台申请应用的AppID值 - appSecret(HBuilderX3.4.18+ 不再提供此参数的可视化配置,详见配置参数安全性问题)
微信开放平台申请应用的AppSecret值 - UniversalLinks
iOS平台通用链接,必须与微信开放平台配置的一致,推荐使用一键生成iOS通用链接
2.前端代码
<template>
<view class="content">
<view class="text-area">
<button @click="wxlogin">微信登陆</button>
</view>
</view>
</template>
<script>
export default {
data() {
return {
title: 'Hello'
}
},
onLoad() {
},
methods: {
wxlogin() {
uni.login({
provider: 'weixin', //使用微信登录
// onlyAuthorize: true,
success: function (loginRes) {
console.log(loginRes.authResult);
console.log("loginRes.authResult.accessToken="+loginRes.authResult.access_token)
uni.request({
url: 'http://192.168.1.9:8085/wx/login', //仅为示例,并非真实接口地址。
method:'GET',
data: {
accessToken:loginRes.authResult.access_token,
openid:loginRes.authResult.openid,
},
});
},
})
}
},
}
</script>
<style>
</style>
这里就简单展示一下,效果图:
点击登陆后就会自动跳转到微信登陆授权页面了。
