今天,我们来总结下我们平常使用的工具函数,希望对大家有用。 1、封装fetch
源码:
代码语言:javascript复制/**
* 封装fetch函数,用Promise做回调
* @type {{get: (function(*=)), post: (function(*=, *=))}}
*/
const fetchUtil = {
get: (url) => {
return new Promise((resolve, reject) => {
fetch(url, {
method: 'GET',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
}
}).then((response) => response.json()).then(response => {
resolve(response);
}).catch(err => {
reject(new Error(err));
});
});
},
post: (url, params) => {
return new Promise((resolve, reject) => {
fetch(url, {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
},
body: params
}).then((response) => response.json()).then(response => {
resolve(response);
}).catch(err => {
reject(new Error(err));
});
});
}
};
export default fetchUtil;
使用:
代码语言:javascript复制import Fetch from "../util/FetchUtil.js";
// post请求
post(){
let params = "";
params = "phone=" "xxxxxx" "&password=" "123456";
Fetch.post("https://carvedu.com/api/user/sms", this.params)
.then(res => {
console.log(res);
})
.catch(err => {
console.log(err);
});
}
// get请求
get() {
Fetch.get("https://carvedu.com/api/courses")
.then(res => {
console.log(res);
})
.catch(err => {
console.log(err);
});
}
2、判断浏览器环境
源码:
代码语言:javascript复制function getSystem(){
const mac = /mac/i,
linux = /linux/i,
win = /win/i;
const platform = navigator.platform.toLowerCase();
if(mac.test(platform)){
return 'MAC';
} else if(win.test(platform)){
return 'WIN';
