angular - 对预检请求的响应未通过访问控制检查：它没有HTTP正常状态(Response to preflight request doesn't pass access control check: It does not have HTTP ok status)

Question

My back-end is running locally on localhost:8090/ and front-end is running on http://localhost:4200/ .

(我的后端在localhost:8090/上localhost:8090/运行，而前端在http://localhost:4200/ 。)

I'm trying to send a POST request to back-end with some data in body and I'm getting this error in browser console.

(我正在尝试向正文发送一些数据的后端POST请求，并且在浏览器控制台中遇到此错误。)

Access to XMLHttpRequest at ' http://localhost:8090/process/ ' from origin ' http://localhost:4200 ' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

(从源' http：// localhost：4200 '的' http：// localhost：8090 / process / '处对XMLHttpRequest的访问已被CORS策略阻止：对预检请求的响应未通过访问控制检查：没有HTTP正常状态。)

Angular Service Function

(角服务功能)

createProcess(){
    const url = 'http://localhost:8090/process/';
    return this.http.post<any>(url, { "botType": "test1", "name": "test2", "processCode": "test3" })
        .pipe(map(user => {
            return user;
        }));
  }

Swagger-UI

(Swagger-UI)

This works in POSTMAN.

(这在POSTMAN中有效。)
