问题描述
import {Page, Platform} from 'ionic-angular';
import { Http, Headers, Response, RequestOptions, HTTP_PROVIDERS} from 'angular2/http';
import { bootstrap } from 'angular2/platform/browser';
import { Component, Injectable, Inject } from 'angular2/core';
import 'rxjs/Rx';
import { CORE_DIRECTIVES, FORM_DIRECTIVES } from 'angular2/common';
import {Observable} from 'rxjs/Observable';
@Page({
directives: [ CORE_DIRECTIVES, FORM_DIRECTIVES ],
templateUrl: 'build/pages/getting-started/getting-started.html'
})
@Injectable()
export class GettingStartedPage {
public platform;
public networkState;
private headers;
private _apiUrl = 'http://172.16.2.115:3004/message';
subject: string;
message: string;
comments: string;
constructor(platform: Platform, public http: Http) {
this.platform = platform;
this.headers = new Headers();
this.headers.append('Content-Type', 'application/x-www-form-urlencoded');
}
onSubmit(value) {
this.send(value.subject, value.body);
}
send(subject, body)
{
var message = "subject=" + subject + "&body=" + body;
let result = this.http.post(this._apiUrl,
body,
{
headers: this.headers
}).map(res => {
this.comments = res.json();
});
this.send(subject, body).subscribe(res => {
console.log(message);
console.log(this._apiUrl);
});
return result;
}
}
我正在尝试使用Ionic2创建移动应用程序Angular2 beta。这个应用程序将使用POST向Rails Web服务发送电子邮件。 Rails Web服务工作得很好。我似乎没有开始使用移动应用程序。
I am trying to create a mobile app using Ionic2 and Angular2 beta.This app will send an email using POST to a Rails web service. The Rails web service is working just fine. I dont seem to be getting to work the mobile app.
推荐答案
存在误解
this.send(subject, body).subscribe(res => {
console.log(message);
console.log(this._apiUrl);
});
将使用不同的方法
onSubmit(value) {
this.send(value.subject, value.body)
.subscribe(res => {
console.log(message);
console.log(this._apiUrl);
});
}
send(subject, body)
{
var message = "subject=" + subject + "&body=" + body;
return this.http.post(this._apiUrl,
body,
{
headers: this.headers
}).map(res => {
this.comments = res.json();
});
}
