我使用我的服务器URL的标题,我在其中一个组件中声明它,我想在所有组件中使用该标头,我曾经有过服务器调用,但我没有订阅该标题,任何人都可以请帮助我
我的界面组件,
import { Injectable } from '@angular/core';
@Injectable()
export class Config {
header = 'http://localhost/a2server/index.php/';
}
我的main.ts(这里我想使用标题)
var data :any;
constructor(public location: Location,public config:Config,public router: Router, public http: Http, fbld: FormBuilder,public toastr: ToastsManager) {
this.config
.subscribe(header => this.data = data);
console.log(this.data)
我知道我错了,有人可以帮助我吗
注射的,
import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import {Component} from '@angular/core';
import { IDetails } from './details';
import { Config } from '../headers';
@Component({
providers: [Config]
})
@Injectable()
export class GetCustInfo {
header:any;
str = localStorage.getItem('social');
loc = JSON.parse(this.str);
id = this.loc.profile_id;
constructor(private _http: Http,public config:Config) { this.header = this.config.header;}
private _productUrl = this.header+'profile/editcustominfo/'+this.id;
getCustList(): Observable<IDetails[]> {
return this._http.get(this._productUrl)
.map((response: Response) => {
return <IDetails[]> response.json().data[0];
});
}
}

您订阅了observables。对于一个简单的字符串,您只需访问该属性:
...
var key_value = mapStudent.Where(st => st.Key == classID).First();
var listStudent_EditFlag = key_value.Value;
foreach (KeyValuePair<List<Student>, Boolean> pair in listStudent_EditFlag)
{
listStudent_EditFlag[pair.Key] = true;
break;
}
...
