未捕获的ReferenceError:__ng_jsonp____req0_finished在以下位置未定义 [英] Uncaught ReferenceError: __ng_jsonp____req0_finished is not defined at

问题描述

我有一个Angular应用程序，我也在使用JSONP.

I have an Angular application and I'm using JSONP as well.

这是我的服务

import { Injectable } from '@angular/core';
import { Http, Response, Headers, RequestOptions } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import { Page } from './page';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
import { Jsonp } from '@angular/http';

@Injectable()
export class ProductService {

    private urlPage = 'http://api.zanox.com/json/2011-03-01/products?q=iphone&connectid=XXXXXXXXXXXX&programs=12011&callback=JSONP_CALLBACK';

    constructor(private _jsonp: Jsonp) { }

    getPage(): Observable<Page> {
        return this._jsonp.get(this.urlPage).map(this.extractData).catch(this.handleError);
    }

    private extractData(res: Response) {
        let body = res.json();
        return body || {};
    }

    private handleError(error: any) {
        let errMsg = (error.message) ? error.message :
            error.status ? `${error.status} - ${error.statusText}` : 'Server error';
        console.error(errMsg);
        return Observable.throw(errMsg);
    }

}

我收到此错误:

未捕获的ReferenceError:__ng_jsonp____req0_finished未定义 在产品上吗?q = iphone& connectid = XXXXXXXXXX& programs = 12011& callback = __ ng_jsonp ____ req0_finished:1

如何解决?

我解决了该错误，可以回溯到Angular的2.3.1版本.该错误发生在2.4.X版本中.

I solved this bug going back to the version 2.3.1 of Angular. The bug happens in the version 2.4.X.
