在选择图片后使用wx.getFileSystemManage.readFile转化base64是出现报错：VM22195:1 readFile:fail parameter error: parameter.filePath should be String instead of Undefined
实在想不通啊！
代码如下：
user.chooseImage({
count: 1,
sizeType: ['compressed'],
sourceType: ['album', 'camera'],
})
.then(res=>{
// 选择图片成功，开始上传
// 这里res是可以打印出来的
console.log(res)
//var filePath = res.tempFilePaths[0]
return user.getFileSystemManagerReadFile({
filePath: res.tempFilePaths[0], // 这里出现问题
encoding: 'base64'
})
})
.then(res=>{
console.log('base64', res)
})
.catch(err=>{
console.log('头像更新错误：', err)
})
我的不报错
