          console.log(result)
          if (!result || !result.list) {
            this.tableStatusData = []
            this.tableDataTotal = 0
          } else {
            this.tableStatusData = result.list
            this.tableDataTotal = parseInt(result.count)
          }
          if (this.tableDataTotal > 0) {
            this.isShow = true
          } else {
            this.isShow = false
          }
        }
      })
    }

目前的问题是在开发环境Json.parse没有报错 但是在测试环境报了这个错：Unexpected string in JSON at position 901 。相同的数据为什么会出现这种情况啊
