export default class HttpUtils {
//基于 fetch 封装的 GET请求
static getFatch(url) {
return new Promise((resolve, reject) => {
fetch(url)
.then((response)) => {
if (response.ok) {
return response.json();
} else {

//基于 fetch 封装的 POST请求

method: 'POST',
header: {

}
使用方法
import HttpUtils from './HttpUtils'
export default class UserFatch extends Component {
HTTPUtil.post(url, params)
.then((json) => {
//处理 请求success
if(json.code === 0 ){
//我们假设业务定义code为0时，数据正常
}else{
//处理自定义异常
this.doException(json);
}
},(json) => {
//TODO 处理请求fail
})
}
下面的使用回调函数来封装的Fatch网络请求

* params:请求参数
* successCallback:成功回调
* failCallback:失败回调
