我試圖從使用angular2 rest服務的本地服務器獲取產品。當我執行GET時，出現以下錯誤。我可以使用Insomnia休息客戶端從服務器獲取項目，所以我知道問題不在服務器中。我也檢查了網址，並確保沒有錯誤。任何想法我可以檢查什麼？我使用的NG-CLI運行應用程序...Angular2：嘗試使用休息服務從服務器獲取Json時出現奇怪的模糊錯誤
我的錯誤：
http://10.60.160.34/BRMServices/WebEnquiry//POSEnquiry/293
Failed to load resource: net::ERR_CONNECTION_RESET
app.component.ts:32
failureServer error
我休息服務：
import { Injectable } from '@angular/core';
import { Http, Headers, Response, RequestOptions } from "@angular/http";
import { Observable } from "rxjs/Rx";
import { ProductModel } from "../models/product.model";
//import 'rxjs/add/operator/map';
//import 'rxjs/add/operator/catch';
//import 'rxjs/add/observable/throw'
@Injectable()
export class RestService {
public API_URL: string = "http://10.60.160.34/BRMServices/WebEnquiry/";
private headers: Headers;
private options: RequestOptions;
constructor(private http: Http){
this.init();
}
init() {
this.headers = new Headers({ 'Content-Type': 'application/json' });
this.options = new RequestOptions({ headers: this.headers });
}
getProduct(barcode: string): Observable<ProductModel> {
return this.http.get(this.API_URL + "/POSEnquiry/" + barcode, this.options)
.map((res: Response) => res.json())
.catch((error: any) => Observable.throw(error.json().error || 'Server error'));
}
}
我app.component.ts：
import { Component } from '@angular/core';
import { RestService } from "./services/rest.service";
import { ProductModel } from "./models/product.model";
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
product: ProductModel;
constructor(private restService: RestService){}
submitBarcode(barcode: HTMLInputElement){
this.restService.getProduct(barcode.value)
.subscribe((res) => {
//product = res;
console.log(res);
}, (res) => {
console.log("failure" + res);
});
//console.log("product: " + product);
}
}
