您好我正在尝试在离子2中创建一个注册页面,将用户名,电子邮件和密码发布到我使用的API。但我收到此错误TypeError: this.http.post is not a function
。我已经搜索过这个问题并尝试但它对我不起作用。
这是我的signup.js:
import {Injectable, Inject} from 'angular2/core';
import {Page, NavController} from 'ionic-angular';
import {TabsPage} from '../tabs/tabs';
import {UserData} from '../../providers/user-data';
import {Http, Headers, RequestOptions} from 'angular2/http';
import {Observable} from 'rxjs/Observable';
import 'rxjs/Rx';
@Page({
templateUrl: 'build/pages/signup/signup.html'
})
@Injectable()
export class SignupPage {
static get parameters() {
return [[Http], [NavController], [UserData]];
}
constructor(nav, userData, http) {
this.nav = nav;
this.userData = userData;
this.http = http;
this.signup = {};
this.submitted = false;
}
onSignup(form) {
let body = JSON.stringify(form.value);
let headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded');
headers.append('Accept', 'application/json');
let options = new RequestOptions({ headers: headers });
this.http.post('http://localhost:8000/api/v1/auth/register', body, options)
.map(res => res.json())
.subscribe(
data => this.success = data
)
.catch(this.handleError);
}
handleError(error) {
console.error(error);
return Observable.throw(error.json().error || 'Server error');
}
}
请帮忙!
答案 0 :(得分:2)
我认为这是因为您在parameters
getter和构造函数级别使用的提供程序的顺序:
static get parameters() {
return [[Http], [NavController], [UserData]]; // <-----
}
constructor(nav, userData, http) { // <-----
}
您需要在两个级别定义相同的顺序(以及正确的方括号),如下所述:
static get parameters() {
return [[NavController, UserData, Http]]; // <-----
}
constructor(nav, userData, http) {
}
