如果互相没有加好友，就收不到内容

[kilik52]

我的账号开了不需要验证就能加我好友功能。

然后对方给我发消息，在weixinbot.js的第1377行， 打印出来的_context17的内容是：

Context {
  tryEntries: [ { tryLoc: 'root', completion: [Object] } ],
  prev: 0,
  next: 0,
  _sent: undefined,
  sent: undefined,
  done: false,
  delegate: null }
Context {
  tryEntries: [ { tryLoc: 'root', completion: [Object] } ],
  prev: 0,
  next: 12,
  _sent: undefined,
  sent: undefined,
  done: false,
  delegate: null }
Context {
  tryEntries: [ { tryLoc: 'root', completion: [Object] } ],
  prev: 12,
  next: 14,
  _sent: null,
  sent: null,
  done: false,
  delegate: null }
Context {
  tryEntries: [ { tryLoc: 'root', completion: [Object] } ],
  prev: 14,
  next: 'end',
  _sent: null,
  sent: null,
  done: false,
  delegate: null }
