同步思想-未捕获错误抛出

这段代码，乍一看没啥错误，

  1.  async getEthBalance () {
  2.       this.loading = true
  3.       const eth = await CethAction.getEthBalance(this.account)
  4.       this.$message.success('开始获取getEthBalance' + eth)
  5.       this.loading = false
  6.     },

结合交互，一旦函数抛错处理，loading可能一直为true

优化结果处理

  1.   async mint () {
  2.       this.loading = true
  3.       try {
  4.         await CethAction.mint(this.account, '0.1')
  5.       } catch (error) {
  6.         console.error(error)
  7.       } finally {
  8.         this.loading = false
  9.       }
  10.     },
