Question

为什么调试器行未命中？请让我知道如何修改代码，以便使其成功。

async _store_token(tok){  // tried this line with and without 'async', just to see
      debugger;     // THIS LINE DOESN'T GET CAUGHT BY DEBUGGER
  }

  componentWillMount(){

     //debugger;

     axios({
  method: 'post',
  url: BASE_URL + '/users/login',
  data: {
      email: "email1@mail.com",
    password: "passpass"
  }
})
  .then(async function (res) {
    debugger;                       // CODE IS FINE AT THIS DEBUG STATEMENT
    _store_token(res.token);  // TRIED TO USE 'this._store_token(res.token);'
                               // but it didn't work either



})

Answer 1

原因是scope关键字中的this。可能是您想使用箭头方法功能。

示例

then(async res => {})

我不确定在这个简单的示例中为什么调试器行没有被点击
