Angular 8-httpClient的Get方法转换为Options方法 [英] Angular 8 - httpClient Get method transforms to Options method

问题描述

我正在尝试将Get请求发送到我的服务器(Microsoft 2012).我已经添加了此解决方案.但这是解决方案，我的get请求已转换为Options方法.

I am trying to send Get request to my server(Microsoft 2012). I have already added this solution. But in this is solution my get request transformed to Options method.

const httpOptions = {
  headers: new HttpHeaders({
    'Content-Type': 'application/vnd.sas.datamgmt.jobflow.metadata+json; charset=utf-8',
    'Authorization': 'Basic' + btoa('username:password')
  })
};

我还添加了:

    httpOptions.headers.set('username', 'password');
    httpOptions.headers.append('Access-Control-Allow-Origin', '*');
    httpOptions.headers.append('Access-Control-Allow-Credentials', 'true');
    httpOptions.headers.append('Access-Control-Allow-Methods', 'GET,POST,OPTIONS');
    this.typesOfDBs = this.http.get<Info[]>(this.ROOT_URL, httpOptions);

我查看了我的请求，发现该请求现在是选项"请求.如何处理它并以Get方法发送请求?

I watched my request and I saw the request is now Options request. How can I handle it and send request as Get method?

推荐答案

我使用nodejs代理来解决此问题.Nodejs可以轻松处理它.您必须从angular向Node.js发送请求.并从nodejs到restapi.

I used nodejs proxy to solve this question. Nodejs handled it easily. You must send request to nodejs from angular. And to restapi from nodejs.
