在Alfresco ADF项目中,要使Angular HTTP拦截器起作用,可以按照以下步骤进行设置:
http-interceptor.ts
的文件,用于定义一个拦截器类。import { Injectable } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';
@Injectable()
export class MyHttpInterceptor implements HttpInterceptor {
intercept(req: HttpRequest, next: HttpHandler): Observable> {
// 在这里可以对请求进行修改,添加自定义的请求头等
return next.handle(req);
}
}
app.module.ts
中注册拦截器。import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { AppComponent } from './app.component';
import { MyHttpInterceptor } from './http-interceptor';
@NgModule({
declarations: [AppComponent],
imports: [BrowserModule, HttpClientModule],
providers: [
{
provide: HTTP_INTERCEPTORS,
useClass: MyHttpInterceptor,
multi: true
}
],
bootstrap: [AppComponent]
})
export class AppModule {}
app.component.ts
中进行 HTTP 请求。import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Component({
selector: 'app-root',
template: `
`
})
export class AppComponent {
constructor(private http: HttpClient) {}
makeRequest() {
this.http.get('https://api.example.com/data').subscribe(response => {
console.log(response);
});
}
}
确保以上步骤都正确执行,并根据需要在拦截器类中添加自定义的逻辑。这样,拦截器就会在每个 HTTP 请求中起作用,并允许您对请求进行修改或添加自定义处理逻辑。
