我想让你充当前端开发专家。我将提供一些关于Js、Node等前端代码问题的具体信息，而你的工作就是想出为我解决问题的策略。这可能包括建议代码、代码逻辑思路策略。
我的请求是【我现在在做一个微信小程序，遇到一些问题，第一个是新人注册账户中，创建好后不能自动跳转到profile页面，当点击主页按键，在点击profile按键会发现注册时填写的个人信息没有自动写进profile页，同时头像上传比例还有问题，头像不应该随意修改上传图片的比例。此外点击推出登录后还是会跳转回profile页面。以下是一些代码 // miniprogram/pages/common-package/login/login.js
Page({
data: {
isLoading: true,
retryShow: false,
isRendered: false
},
onLoad(options) {
console.log("登录页onLoad触发，参数：", options || "无参数");
this.setData({ isRendered: true });
setTimeout(() => {
this.autoLoginFlow();
}, 100);
},
onShow() {
console.log("登录页onShow触发");
this.setData({ isLoading: this.data.isLoading });
},
onReady() {
console.log("登录页onReady触发");
this.setData({ isRendered: true });
},
autoLoginFlow() {
setTimeout(() => {
this.setData({ isLoading: true, retryShow: false });
const localIsLogin = wx.getStorageSync("isLogin") || false;
const localUserInfo = wx.getStorageSync("userInfo") || {};
if (localIsLogin && localUserInfo._id) {
this.jumpToProfile();
return;
}
this.checkCloudRegisterAndLogin();
}, 300);
},
checkCloudRegisterAndLogin() {
wx.cloud.callFunction({
name: "getUser",
success: (res) => {
this.setData({ isLoading: false });
const { code, data, error } = res.result || {};
if (code !== 0) {
this.setData({ retryShow: true });
wx.showToast({ title: `查询失败：${error || "未知错误"}`, icon: "none" });
console.error("getUser 云函数查询失败：", error);
return;
}
const cloudUserList = res.result.data || [];
if (cloudUserList.length === 0) {
this.jumpToRegister();
return;
}
const userData = cloudUserList[0];
wx.setStorageSync("isLogin", true);
wx.setStorageSync("userInfo", {
_id: userData._id,
nickName: userData.nickName,
avatarUrl: userData.avatarUrl || "/images/icons/default-avatar.png",
grade: userData.grade,
major: userData.major
});
this.jumpToProfile();
},
fail: (err) => {
this.setData({ isLoading: false, retryShow: true });
wx.showToast({ title: "网络错误，点击重试", icon: "none" });
console.error("自动登录查数据库失败：", err);
}
});
},
jumpToProfile() {
setTimeout(() => {
wx.switchTab({
url: "/pages/profile/profile",
fail: () => {
wx.showToast({ title: "跳转失败，手动进入我的页", icon: "none" });
}
