uniapp微信获取用户信息授权(两种方法)

方法一

**使用button组件(open-type属性)**
<button open-type="getUserInfo"@click="loginMP"></button>

			uni.getUserInfo({
					provider:"weixin",
					success(userInfo) {
						loginMP().then(res=>{
							 uni.setStorageSync('token', res.result.token)
							uni.getUserInfo({
								provider:"weixin",
								success(res) {
									console.log(res);
								},
								fail(err) {
									console.log(err);
								}
							})
							uni.showToast({
								title: '登录成功'
							});
						}).catch(err=>{
							uni.showModal({
								title: "提示",
								content: '稍后重试'+err.message,
								showCancel: false,
							});
						})
					}
			

方法二

**使用openSetting引导用户打开相应的权限,相关的API还有getSetting **

				uni.authorize({
					scope:"scope.scope.userInfo",
					success(res) {
						console.log(res);
					},
					fail() {
						uni.openSetting({
							success(authSetting) {
								console.log(authSetting);
							}
						})
					}
				})
