wx.shareEmojiToGroup({
  imagePath: this.data.url,
  needShowEntrance: false,
  success() {
    console.log("shareEmojiToGroup success");
  },
  fail(err) {
    console.log("shareEmojiToGroup fail", err);
  },
  compelete() {
    console.log("shareEmojiToGroup compelete");
  },
});

同样的代码，换成 shareEmojiToGroup 就一切正常
