错误：InvalidPipeArgument

Question

尝试使用API​​调用加载数据时，我收到上述错误。

      ngOnInit(http1: Http) {

    this.rowData = http1.get('https://api.myjson.com/bins/15psn9');
}

Answer 1

Http返回Observable。因此，您需要按以下方式更改代码。

ngOnInit(http1: Http) {
  http1.get('https://api.myjson.com/bins/15psn9')
     .subscribe(data => this.rowData = data);
}
