要隐藏浏览器控制台错误消息，当状态不等于200时，可以使用Angular的Http拦截器来处理。以下是一个使用Http拦截器隐藏错误消息的示例：

1. 创建一个新的Angular服务，例如HttpInterceptorService：

import { Injectable } from '@angular/core';
import { HttpInterceptor, HttpHandler, HttpRequest, HttpErrorResponse } from '@angular/common/http';
import { catchError } from 'rxjs/operators';
import { throwError } from 'rxjs';

@Injectable()
export class HttpInterceptorService implements HttpInterceptor {

  intercept(req: HttpRequest, next: HttpHandler) {
    return next.handle(req).pipe(
      catchError((error: HttpErrorResponse) => {
        if (error.status !== 200) {
          // 隐藏控制台错误消息
          return throwError('');
        } else {
          return throwError(error);
        }
      })
    );
  }

}

2. 在应用的模块中提供该服务：

import { NgModule } from '@angular/core';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { HttpInterceptorService } from './http-interceptor.service';

@NgModule({
  imports: [
    ...
    HttpClientModule
  ],
  providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: HttpInterceptorService,
      multi: true
    }
  ],
  ...
})
export class AppModule { }

通过这样配置，当HTTP请求的状态不等于200时，控制台将不会显示错误消息。
