Uniapp/Easywechat/Fastadmin实现微信小程序登录、session_key、获取用户信息、获取手机号

开发准备: 小程序 appid，secret， easywechat

获取session_key

用户端自登录(获取code) -> 请求后端接口获取session_key -> 用户端保存session_key

1.用户端获取code

        getSessionKey(){
                uni.login({
                    success: (info) => {
                        console.log('Login信息', info)
                        uni.request({
                            url: this.domain + '/api/wechat/getSessionKey',
                            method:'POST',
                            data: {
                                code: info.code
                            },
                            success: (res) => {
                                this.session_key = res.data.data.session_key
                            }
                        })
                    }
                })
            },

2.接口

function getSessionKey(){
    $data = $this->app->auth->session($this->post['code']);
    $this->success('获取session_key成功', $data);
}

3.请求接口获取session_key

获取用户信息

用户端自获取用户信息(获取 iv + encryptedData + signature + session_key) -> 请求后端接口获取token -> 用户端保存token

1.放置请求授权用户信息按钮

<button open-type="getUserInfo" @getuserinfo="getUserInfo">获取用户信息</button>

2.打印授权信息

3.后端接口

function getUserInfo(){
    $data = $this->app->auth->session($this->post['code']);
    $this->success('获取session_key成功', $data);
}

接口返回信息

获取用户手机号

注： 只有300元微信认证的小程序才有权限获取用户手机号

用户端弹窗请求授权获取手机号( 获取 iv + encryptedData + session_key ) -> 请求后端接口获取手机号

1.放置请求授权手机号弹窗按钮

<button open-type="getPhoneNumber" @getphonenumber="getPhoneNumber">获取手机号</button>

2.弹出请求授权手机号弹窗

3.打印授权信息

4.请求接口获取手机号

注: session_key 是第一步获得的 session_key
