在进行Http GET调用时，获取"OPTIONS https://riskassessmentidtypes.px-npe01.com/customer-credit/ 0 ()“
提问于 2018-06-21 01:40:41
我正在做一个Angular 5的内部项目。在这里，我们尝试对PCF环境中存在的一个URL进行Http GET调用。在进行此呼叫时，我收到以下控制台消息：
OPTIONS https://riskassessmentidtypes.px-npe01.com/customer-credit/ 0 ()
进度事件：{isTrusted: true，lengthComputable: false，已加载: 0，总计: 0，类型：“错误”，…}
我的代码: processrequest.component.ts
this.httpService.getDetails(url, data).subscribe(
res => {
this.loading = false;
console.log("response-----" + res);
this.serviceresponsetime = new Date().getTime() - startFrom;
},
error => {
this.loading = false;
console.log(error);
this.serviceresponsetime = new Date().getTime() - startFrom;
//util.parseServiceResponse(error, false);
//this.responseData = util.responseData;
}
);http.service.ts
@Injectable()
export class HttpService {
data: any;
headers = new Headers();
constructor(private http: Http) {
this.headers.append('Content-Type', "application/json");
this.headers.append('Accept', "application/json");
this.headers.append('senderid', "dsd");
this.headers.append('applicationid', "adsd");
this.headers.append('servicetransactionid', "asds");
this.headers.append('channelid', "asdsd");
}
// get service call
getDetails(url, params) {
console.log("http service - inside getDetails function");
let options = new RequestOptions();
options.headers = this.headers;
if (params) {
options.params = params;
}
return this.http.get(url, options)
.map((response) => response.json())
.catch((error: any) => Observable.throw(error.json() || 'server error'));
}在此之前非常感谢。因为我是Angular的新手，所以我被困在这里。请在下面找到错误：

据我所知，很多浏览器都会在发送其他请求之前发送option请求。你可以在你的浏览器开发工具中经常观察到这种行为。据我所知，这不是一个角度问题，而是一个浏览器问题。

我在目标springboot微服务的端点方法级别使用@CrossOrigin解决了这个问题。
我们也可以在控制器类中使用它。
