FileSystemManager.writeFile报错 - WXOPEN Club

 var imgurl = that.data.imgurl;
    let manager = wx.getFileSystemManager()
    var savedFilePath = wx.env.USER_DATA_PATH + '/test/test.png';
    manager.writeFile({
      filePath: savedFilePath,
     
      encoding: imgurl,
      sucess: function (res) {
        console.log("writeFilesucess res:", res)
      },
      fail: function (err) {
        console.log("writeFile fail err:", err)
      },

我写这样的函数报错为writeFile:fail invalid encoding

imgurl为图片base64编码。

求大神给个解答啊，小城市自学狗，身边没有人会，只能求助于你们了，万望帮助
