【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>;    post<T>(url: string, body: any, options?: RequestOptionsArgs): Observable<T>;    put<T>(url: string, body: any, options?: RequestOptionsArgs): Observable<T>;    delete<T>(url: string, options?: RequestOptionsArgs): Observable<T>;    patch<T>(url: string, body: any, options?: RequestOptionsArgs): Observable<T>;    head<T>(url: string, options?: RequestOptionsArgs): Observable<T>;    options<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);}//导出声明方法：BaseUrl：export declare function BaseUrl(url: string): <TFunction extends Function>(target: TFunction) => TFunction;//导出声明方法：默认头儿们；export declare function DefaultHeaders(headers: any): <TFunction extends Function>(target: TFunction) => TFunction;//导出声明变量：Path；export declare var Path: (key?: string) => (target: RebirthHttp, propertyKey: string | symbol, parameterIndex: number) => void;//导出声明变量：Query；export declare var Query: (key?: string) => (target: RebirthHttp, propertyKey: string | symbol, parameterIndex: number) => void;//导出声明变量：Body；export declare var Body: (target: RebirthHttp, propertyKey: string | symbol, parameterIndex: number) => void;//导出声明变量：Header；export declare var Header: (key?: string) => (target: RebirthHttp, propertyKey: string | symbol, parameterIndex: number) => void;//导出声明方法：头儿们export declare function Headers(headersDef: any): (target: RebirthHttp, propertyKey: string, descriptor: any) => any;//导出声明方法：Producesexport declare function Produces(producesDef: string): (target: RebirthHttp, propertyKey: string, descriptor: any) => any;//导出声明const：GETexport declare const GET: (url: string) => (target: RebirthHttp, propertyKey: string, descriptor: any) => any;//导出声明const：JSONPexport declare const JSONP: (url: string) => (target: RebirthHttp, propertyKey: string, descriptor: any) => any;//导出声明const：POSTexport declare const POST: (url: string) => (target: RebirthHttp, propertyKey: string, descriptor: any) => any;//导出声明const：PUTexport declare const PUT: (url: string) => (target: RebirthHttp, propertyKey: string, descriptor: any) => any;//导出声明const：DELETEexport declare const DELETE: (url: string) => (target: RebirthHttp, propertyKey: string, descriptor: any) => any;//导出声明const：HEADexport declare const HEAD: (url: string) => (target: RebirthHttp, propertyKey: string, descriptor: any) => any;////导出声明const：PATCHexport declare const PATCH: (url: string) => (target: RebirthHttp, propertyKey: string, descriptor: any) => any;//导出声明const REBIRTH_HTTP_PROVIDERSexport declare const REBIRTH_HTTP_PROVIDERS: Array<any>;
