我正在按照NativeScript的步骤tutorial进行操作,但我面临以下问题:
当我尝试通过Angular服务发布帖子请求时,我收到以下错误:
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /\?page=([^&\ ]+)
RewriteRule ^/?$ /%1? [L,R=301]
我的代码看起来与NativeScript官方文档中的代码非常相似:
JS: {"message":"The specified content type was not found.","errorCode":611}
组件类:
import { Injectable } from '@angular/core';
import { Http, Headers, Response } from '@angular/http';
import { User } from './user';
import { Config } from '../config';
import { Observable } from 'rxjs/Rx';
import 'rxjs/add/operator/do';
import 'rxjs/add/operator/map';
@Injectable()
export class UserService {
constructor(private _http: Http) { }
register(user: User): Observable<Response> {
const headers = new Headers();
headers.append('Content-Type', 'application/json');
const url = `${Config.apiUrl}/Users`;
const body = JSON.stringify({
Username: user.email,
Email: user.email,
Password: user.password
});
return this._http.post(url, body, { headers })
.catch(this.handleErrors);
}
handleErrors(error: Response) {
console.error(JSON.stringify(error.json()));
return Observable.throw(error);
}
}
在Android和IO下测试,都会引发同样的错误。
在这种情况下,不是signUp() {
this._user.register(this.user).subscribe(
() => {
alert('Your account has been successfully created.');
this.toggleDisplay();
},
() => {
// errors here...
alert('Unfortunately we were unable to create your account.');
}
);
}
预期application/json
吗?
如果我更改了类型,我会收到另一个错误,说明类型丢失或无效。
有人可以指出我错过了什么吗?
