将{number，Observable<string>}转换为Observable<number，string>

import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';

// 原始的{number, Observable<string>}类型数据
const data: {number, Observable<string>}[] = [
  { number: 1, observable: new Observable<string>(...) },
  { number: 2, observable: new Observable<string>(...) },
  ...
];

// 使用map操作符转换数据类型
const transformedData: Observable<{number, string}> = from(data).pipe(
  map(item => ({ number: item.number, string: item.observable }))
);

// 订阅转换后的Observable
transformedData.subscribe(value => {
  console.log(value.number, value.string);
});
