uniapp如何调用微信授权

**使用button组件（open-type属性）**

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,
});
})
}

**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);
}
})
}
})
