subscribe(next: null | undefined, error: (error: any) => void, complete?: () => void): Subscription;

Question

我正在按照教程进行操作，但出现此错误。 https://docs.abp.io/en/abp/latest/Tutorials/Part-3?UI=NG&DB=EF

subscribe(next: null | undefined, error: (error: any) => void, complete?: () => void): 订阅；未提供 'error' 的参数。

其实我也没找到我错在哪里。谁能帮我解决这个问题？ authorService

This Error Message Popping when mouse over on subscribe

Answer 1

试试这样：

 request.subscribe(
    () => {
      this.isModalOpen = false;
      this.form.reset();
      this.list.get();
    },
    err => console.error(err)
);

也许你正在使用另一个版本的 RxJS，你需要处理错误或者你在 Typescript 上有另一个配置

Answer 2

request.subscribe({
  next: (response) => {
    // treat recieved data
  },
  error: (error) => {
    // treat error
  },
  complete: () => {
    // define on request complete logic
    // 'complete' is not the same as 'finalize'!!
    // this logic will not be executed if error is fired
  }
})

subscribe(next: null | undefined, error: (error: any) => void, complete?: () => void): Subscription;

subscribe(next: null | undefined, error: (error: any) => void, complete?: () => void): Subscription;
