【Ionic】Argument of type“**Service”is not assignable to parameter of type 'RebirthHttp'.

一、现象描述

Argument of type“**Service”is not assignable to parameter of type ‘RebirthHttp’.Property’http’ is missing in type ‘DataService’;

二、解决办法

原因是**Service.ts没有继承RebirthHttp；
在原来的**Service.ts基础上继承RebirthHttp即可；
原来的**Service：

@Injectable()
export class DataService {

    }

现在的**Service.ts:

@Injectable()
export class DataService extends RebirthHttp{
    constructor(protected http: Http,
                jsonp: Jsonp,
                protected rebirthHttpProvider: RebirthHttpProvider,
                @Inject(EnvVariables) public envVariables) {
        super({ http, jsonp, rebirthHttpProvider });
    }

这里，需要构造器构造Http，Jsonp，RebirthHttpProbider，并且注入EnvVariables；实现父类http，jsonp，rebirthHttpProvider；
这里的RebirthHttp接口如下（源代码）：

//导包
import { Http, Jsonp, Request, RequestOptions, RequestOptionsArgs } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
//导出接口RebirthHttpInterceptor;
export interface RebirthHttpInterceptor {
    request?: (option: RequestOptions) => RequestOptions | void;//请求
    response?: (response: Observable<any>, request?: RequestOptions) => Observable<any> | void;
}
//导出声明类：RebirthHttpProvider;
export declare class RebirthHttpProvider {
    private interceptors;//私有接口；
    constructor();//构造器；
    getInterceptors(): RebirthHttpInterceptor[];//获取接口；
    addInterceptor(interceptor: RebirthHttpInterceptor): RebirthHttpProvider;//添加接口；
    addRequestInterceptor(interceptor: (res: RequestOptions) => RequestOptions)://添加请求接口； RebirthHttpProvider;
    addResponseInterceptor(interceptor: (res: any) => any): RebirthHttpProvider;//添加响应接口
    addResponseErrorInterceptor(interceptor: (res: any) => any): RebirthHttpProvider;//添加错误响应接口；
    handleRequest(req: RequestOptions): RequestOptions;//请求处理；
    handleResponse(res: Observable<any>, request?: RequestOptions): Observable<any>;//响应处理；
    baseUrl(host: string, excludes?: RegExp[]): RebirthHttpProvider;//基本Url；
    headers(headers?: {}): RebirthHttpProvider;//头们
    json(): RebirthHttpProvider;//json；
}
//导出声明类RebirthHttp;
export declare class RebirthHttp {
    protected http: Http;
    protected jsonp: Jsonp;
    protected rebirthHttpProvider: RebirthHttpProvider;
    constructor(option?: {
        http?: Http;
        jsonp?: Jsonp;
        rebirthHttpProvider?: RebirthHttpProvider;
    });
    protected getBaseUrl(): string;
    protected getDefaultHeaders(): Object;
    protected requestInterceptor(req: RequestOptions): RequestOptions | void;
    protected responseInterceptor(res: Observable<any>, request?: RequestOptions): Observable<any> | void;
}
//导出声明类RebirthHttpService服务；
export declare class RebirthHttpService {
    private http;
    private rebirthHttpProvider;
    enableJson: boolean;
    constructor(http: Http, rebirthHttpProvider: RebirthHttpProvider);
    request<T>(url: string | Request, options?: RequestOptionsArgs): Observable<T>;
    get<T>(url: string, options?: RequestOptionsArgs): Observable<T>;

    protected requestInterceptor(req: RequestOptions): RequestOptions | void;
    protected responseInterceptor(res: Observable<any>, request?: RequestOptions): Observable<any> | void;
    private handleRequest<T>(requestOptions);
}
