Question

我在IONIC 3项目中有多个http.post请求。我需要保留调用之间的会话状态。我给服务器打电话的方式如下：

this.http.post('http://192.168.1.107:7777/mobile/Open_a').
subscribe(
  (data:any) => 
  {

// first processing data for the first call here.
// next calling the server for the second time and passing the data back to the server

// start of second call
this.http.post('http://192.168.1.107:7777/mobile/Open_b',
  {params: {clientdata:"test data"}}).
  subscribe((data2:any)=>
  {
      console.log(data2);
  },
  err2 =>
  {
    console.log('error happened!');
    console.log(err2.message);
    let alert = this.alertCtrl.create({
      title: 'Connection error',
      subTitle: err2.message,
      buttons: ['Dismiss']
    });
    alert.present();
  }
  );
  // end of second call code},


 err =>
  {
    console.log('error happened!');
    console.log(err.message);
    ProductDataProvider.ItemsLoaded=true;
    ProductDataProvider.IsLoading=false;
    let alert = this.alertCtrl.create({
      title: 'Connection error',
      subTitle: err.message,
      buttons: ['Dismiss']
    });
    alert.present();
  }

);

问题在于对服务器的两个调用都可以工作，但是会话状态没有保留。有人可以指出我在做什么错吗？

任何建议都将受到高度赞赏。

你真心

仅与withCredetials：true一起使用

this.http.post（ProductDataProvider.Server +'/ mobile / index'，{search：searchstr}，{withCredentials：true}）...

保留IONIC 3 http.post请求之间的会话状态
