下面是一个使用查询参数创建自定义端点的示例代码,用于在Angular 9 NgRx Data中添加方法:
npm install @ngrx/store @ngrx/effects @ngrx/entity @ngrx/data
ng generate service custom-endpoint
custom-endpoint.service.ts
文件中添加以下代码:import { Injectable } from '@angular/core';
import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs';
@Injectable({
providedIn: 'root'
})
export class CustomEndpointService {
private apiUrl = 'http://your-api-url.com'; // 替换为您的API URL
constructor(private http: HttpClient) { }
// 添加自定义端点方法
addDataWithQueryParams(queryParams: any): Observable {
const params = new HttpParams({ fromObject: queryParams });
return this.http.post(`${this.apiUrl}/custom-endpoint`, null, { params });
}
}
import { Component } from '@angular/core';
import { CustomEndpointService } from './custom-endpoint.service';
@Component({
selector: 'app-your-component',
template: `
`
})
export class YourComponent {
constructor(private customEndpointService: CustomEndpointService) { }
addData() {
const queryParams = {
param1: 'value1',
param2: 'value2'
};
this.customEndpointService.addDataWithQueryParams(queryParams)
.subscribe(response => {
console.log(response);
});
}
}
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';
import { CustomEndpointService } from './custom-endpoint.service';
@NgModule({
imports: [
HttpClientModule
],
providers: [
CustomEndpointService
]
})
export class YourModule { }
请注意,这只是一个示例代码,您需要根据您的实际情况进行适当的更改。替换your-api-url.com
为您的API URL,并根据您的需要修改自定义端点服务的方法和参数。
希望这可以帮助到您!
