ajax 的封装 请确保项目中能够使用 promise，includes，需要先引入 babel-polyfill
if (!window.Promise) {
window.Promise = Promise;
}本项目依赖 axios，需要在工程中先安装 axios
yarn add axios # 安装依赖
npm i axios --save # 安装依赖
yarn add @util/ajax # 安装依赖
npm i @util/ajax --save # 安装依赖import CreateAjax from '@util/ajax';
const demoAjax = new CreateAjax(config);
demoAjax.postJSON(opt);
demoAjax.getJSON(opt);
demoAjax.putJSON(opt);
demoAjax.deleteJSON(opt);
demoAjax.downloadFile(opt);
demoAjax.postFormData(opt);创建 ajax 时的入参
export interface createAjaxOption {
showLoading?: Function; // 显示loading方法
hideLoading?: Function; // 隐藏loading方法
loginCallback?: Function; // 未登录的回调
errorMsgHandler: Function; // 异常消息处理方法
requestConfig: any; // 请求的入参，可以配置公共的入参，如headers的ak或uk，数据结构同AxiosRequestConfig
beforeRequestHandler?: Function; // 请求前的处理，如：获取签名等
projectName?: string; // 项目名称 主要用于接口缓存indexDB的storeName
}业务层的入参
export interface ajaxOption extends AxiosRequestConfig {
cache?: boolean; // 是否启用接口缓存
loading?: boolean; // 是否显示loading
isHandleError: boolean; // 业务处理异常
}
export interface AxiosRequestConfig {
url?: string;
method?: Method;
baseURL?: string;
transformRequest?: AxiosTransformer | AxiosTransformer[];
transformResponse?: AxiosTransformer | AxiosTransformer[];
headers?: any;
params?: any;
paramsSerializer?: (params: any) => string;
data?: any;
timeout?: number;
withCredentials?: boolean;
adapter?: AxiosAdapter;
auth?: AxiosBasicCredentials;
responseType?: ResponseType;
xsrfCookieName?: string;
xsrfHeaderName?: string;
onUploadProgress?: (progressEvent: any) => void;
onDownloadProgress?: (progressEvent: any) => void;
maxContentLength?: number;
validateStatus?: (status: number) => boolean;
maxRedirects?: number;
socketPath?: string | null;
httpAgent?: any;
httpsAgent?: any;
proxy?: AxiosProxyConfig | false;
cancelToken?: CancelToken;
}
// 默认的业务参数
const req: AxiosRequestConfig = {
...mergeOption.requestConfig,
method: 'GET',
url: '',
data: null,
params: null,
headers: {
'Content-Type': 'application/json; charset=UTF-8',
},
responseType: 'json',
