微信小程序--自制简易mock.js_页面挡板

http.js：http(以post为例) && mock

const app = getApp();
// 接口对应表
const apiList = [
	{
		path: "../pages/index/mock",// 页面挡板文件地址
		url: "getDataByService",// 接口方法名
		fnName: "getData"// mock文件中接口对应的方法名
	},
]

// 封装http 请求方法
const http = (params, resolve, reject) => {
	wx.showLoading({ mask: true });
	wx.request({
		url: app.globalData.apiUrl + params.url,// 拼接全局ip + 方法名
		header: { "Content-Type": "application/x-www-form-urlencoded" },
		method: 'POST',
		data: params.data,
		success: (res) => {
			wx.hideLoading();
			resolve(res);
		},
		fail: (e) => reject(e)
	})
}

// mock
const mock = (params, resolve, reject) => {
	for (let item of apiList) {
		if (item.url === params.url) {
			let path = require(item.path);
			resolve(path[item.fnName]);
		}
	}
	reject({ errMsg: `未发现url：${params.url}，请先在apiList中定义` });
}

export const post = (params) => {
	return new Promise((resolve, reject) => {
		app.globalData.isMock ? mock(params, resolve, reject) : http(params, resolve, reject);
	})
}
