腾讯云上传图片

需要下载cos-wx-sdk-v5并引入
命令yarn install cos-wx-sdk-v5

import COS from "cos-wx-sdk-v5";

 <img v-if="imgUrl" :src="imgUrl" alt />
 <img v-else :src="imagePath" @click="selectPhoto" mode="aspectFill" />

   // 上传图片
    selectPhoto() {
      var that = this;
      var cos = new COS({
        getAuthorization: function(params, callback) {
          //获取签名 必填参数
          // 方法二（适用于前端调试）
          var authorization = COS.getAuthorization({
            SecretId: "XXXXXXXXXXXXXXXXXXXXXX",
            SecretKey: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
            // stsToken: that.sign.credentials.sessionToken,
            Method: params.Method,
            Key: params.Key
          });
          console.log(params);
          callback(authorization);
        }
