oh-package.json5 引入库
retofit 需要使用2.0.1-rc.0 以上版本修复了retrofit发送网络请求响应结果未正常解析的问题。 ohos/retrofit: 2.0.1-rc.0,ohos/httpclient: 2.0.1-rc.5,
页面使用
Entry
Component
struct LoginPage {State viewModel: LoginViewModel new LoginViewModel().....省略Button(登录).width(85%).height(50).margin({ top: 65 }).onClick(() {if (StrUtil.isEmpty(this.viewModel.userName)) {ToastUtil.showToast(请输入用户名)return}if (StrUtil.isEmpty(this.viewModel.password)) {ToastUtil.showToast(请输入密码)return}this.viewModel.getToken()})} viewmodel使用
Observed
export class LoginViewModel {userName: string password: string .....省略getToken() {let params new Mapstring, undefined()params[username] this.userNameparams[password] this.passwordbaseApiRequestToken(appService.getToken(params),(result) {Logger.debug( result.accessToken)},//可选参数可不传{onFailed: (error) {}, showLoading: true, loadingStr: zzzzzzz})}
} 定义接口 BasePath(/)
export class AppService extends BaseService {GET(szy/uaa/oauth/token)async getToken(QueryMap params: Mapstring, undefined): PromiseResponseApiResponseToken {return {} as ResponseApiResponseToken}
}httpclient 拦截器
export class LoggingInterceptor implements Interceptor {async intercept(chain: Chain): PromiseResponse {try {let request chain.requestI()let requestBody: RequestBody request.bodylet url request.url as HttpUrlconst connectResponse await chain.proceedI(chain.requestI())let startMessage --${request.method} ${url.url} ${connectResponse.protocol ?? }let contentType: string requestBody.contentlet endMessage -- END ${request.method}LoggerUtils.debug(添加日志拦截器)LoggerUtils.debug(Headers:${JSON.stringify(request.headers)})LoggerUtils.debug(httpStart startMessage)LoggerUtils.debug(contentType contentType)LoggerUtils.debug(Response connectResponse.result)LoggerUtils.debug(httpEnd endMessage)return connectResponse} catch (error) {LoggerUtils.debug(添加日志拦截器 失败)return new PromiseResponse((resolve, reject) {let request chain.requestI()let response chain.proceedI(request)response.then((data) {resolve(data)}).catch((err: Error) {reject(err)});})}}
