代码：

success: (res) => {

//console.log(res.tempImagePath)

})

//console.log(‘成功’)

//console.log(res.tempImagePath)

}

}

})

},

fail(res) {

//console.log(‘压缩失败’, res)

}

})

}

})

// } else {

//   wx.showToast({

//     title: ‘请横向拍照’,

//     icon: ‘none’,

//     duration: 2000

//   })

//   return false

// }

},

打印结果：

1 121918

2 121935

3 121945

怎么越压缩越大了
