提示：之前刚写完一个小程序登录方案没过多少天微信就改了，好吧，这🐦性我懂的，新方案自己先搞个吧

前言

上一篇小程序登录刚刚做好微信就改规则了

一、小程序登录

方案：前端能获取到用户名和头像和openid，就一次都传，后端验证openid是否存在过，没有新建个，有生成token返回

二、操作步骤

1.前端获取头像名称openid等

代码如下：

 wx.login({
      success:function(res1){
      

    code <span class="token operator">=</span> res1<span class="token punctuation">.</span>code
  <span class="token punctuation">}</span><span class="token punctuation">}</span><span class="token punctuation">)</span><span class="token punctuation">;</span>
    wx<span class="token punctuation">.</span><span class="token function">getUserProfile</span><span class="token punctuation">(</span><span class="token punctuation">{<!-- --></span>
      desc<span class="token punctuation">:</span> <span class="token string">'用于完善会员资料'</span><span class="token punctuation">,</span> <span class="token comment">// 声明获取用户个人信息后的用途，后续会展示在弹窗中，请谨慎填写</span>
      success<span class="token punctuation">:</span> <span class="token punctuation">(</span>res<span class="token punctuation">)</span> <span class="token operator">=</span><span class="token operator">&gt;</span> <span class="token punctuation">{<!-- --></span>
        console<span class="token punctuation">.</span><span class="token function">log</span><span class="token punctuation">(</span><span class="token number">2222</span><span class="token punctuation">)</span>
        console<span class="token punctuation">.</span><span class="token function">log</span><span class="token punctuation">(</span>res<span class="token punctuation">)</span>
        console<span class="token punctuation">.</span><span class="token function">log</span><span class="token punctuation">(</span><span class="token number">2222</span><span class="token punctuation">)</span>
        this<span class="token punctuation">.</span><span class="token function">setData</span><span class="token punctuation">(</span><span class="token punctuation">{<!-- --></span>

          hasUserInfo<span class="token punctuation">:</span> true
        <span class="token punctuation">}</span><span class="token punctuation">)</span>
        wx<span class="token punctuation">.</span><span class="token function">request</span><span class="token punctuation">(</span><span class="token punctuation">{<!-- --></span>
           url<span class="token punctuation">:</span> <span class="token string">'http://127.0.0.1:12001/api/frontend/user/checkIdentity'</span><span class="token punctuation">,</span>

          data<span class="token punctuation">:</span> <span class="token punctuation">{<!-- --></span>
            avatarUrl <span class="token punctuation">:</span> res<span class="token punctuation">.</span>userInfo<span class="token punctuation">.</span>avatarUrl<span class="token punctuation">,</span>
            city <span class="token punctuation">:</span> res<span class="token punctuation">.</span>userInfo<span class="token punctuation">.</span>city<span class="token punctuation">,</span>
            country <span class="token punctuation">:</span> res<span class="token punctuation">.</span>userInfo<span class="token punctuation">.</span>country<span class="token punctuation">,</span>
            gender <span class="token punctuation">:</span> res<span class="token punctuation">.</span>userInfo<span class="token punctuation">.</span>gender<span class="token punctuation">,</span>

            province <span class="token punctuation">:</span> res<span class="token punctuation">.</span>userInfo<span class="token punctuation">.</span>province<span class="token punctuation">,</span>
            code<span class="token punctuation">:</span>code
          <span class="token punctuation">}</span><span class="token punctuation">,</span>
          success<span class="token punctuation">:</span> function <span class="token punctuation">(</span>res_user<span class="token punctuation">)</span> <span class="token punctuation">{<!-- --></span>
            console<span class="token punctuation">.</span><span class="token function">log</span><span class="token punctuation">(</span><span class="token number">2222</span><span class="token punctuation">)</span>
          <span class="token punctuation">}</span><span class="token punctuation">,</span> fail<span class="token punctuation">:</span> function <span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token punctuation">{<!-- --></span>
              console<span class="token punctuation">.</span><span class="token function">log</span><span class="token punctuation">(</span><span class="token string">'ajax失败了'</span><span class="token punctuation">)</span>
          <span class="token punctuation">}</span>
        <span class="token punctuation">}</span><span class="token punctuation">)</span>
      <span class="token punctuation">}</span>
    <span class="token punctuation">}</span><span class="token punctuation">)</span>

2.后端操作流程

根据openid检测用户是否存在，不存在新增，存在生成token返回

总结

提示：这个微信改东西以后还是要留意些
