我正在尝试使用Ionic2和Angular2 beta创建移动应用程序。此应用程序将使用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。

Answer 1

存在误解

   this.send(subject, body).subscribe(res => {
        console.log(message);
        console.log(this._apiUrl);
    });

将采用不同的方法

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();
        });              

}

您应该以这种方式重构代码：

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;

    let result = this.http.post(this._apiUrl,
        body, 
        {
            headers: this.headers
        }).map(res => {
            this.comments = res.json();
        });              

    return result;       
}

Angular2，Ionic2发布到网络服务
