“rxjs” observable.throw is not a function
最近在处理Angular Observable错误的的时候,出现了如下错误:
“rxjs” observable.throw is not a function
出现问题的原因:
由于版本变更,原来的写法已经不再使用。
具体代码如下:
private static handleErrors(error: any): Observable{ const errors: string[] = []; let msg = ''; msg = 'Status: ' + error.status; msg += ' - Status Text: ' + error.statusText; msg += ' - url: ' + error.url; msg += ' - Exception Message: ' + error.body.error; errors.push(msg); console.error('An error occurred', errors); return Observable.throw(errors); }
解决方案:
修改代码错误的抛出方式:
import {Observable, throwError} from 'rxjs'; private static handleErrors(error: any): Observable{ const errors: string[] = []; let msg = ''; msg = 'Status: ' + error.status; msg += ' - Status Text: ' + error.statusText; msg += ' - url: ' + error.url; msg += ' - Exception Message: ' + error.body.error; errors.push(msg); console.error('An error occurred', errors); return throwError(errors); }
