钉钉小程序2（对dd httpRequest的封装）
ajax 钉钉有jsapi 但是每次要写的参数太多而且无法拦截来处理其他事物；所以基于这个需求我们将httpRequest上层封装一下promise。
function ddPromisify(fn) {
return function (obj = {}) {
return new Promise((resolve, reject) => {
obj.success = function (res) {
// dd.alert({content:'success'+JSON.stringify(res.data.activity)})
//成功
// console.log("成功了了·····" + res);
// setTimeout(function () {
// dd.httpRequest.hideLoading();
// }, 100);
if(res.data.code==200){
resolve(res)
}else{//抛出异常
// setTimeout(function () {
// dd.httpRequest.hideLoading();
// }, 100);
// dd.httpRequest.showModal({
// title: '提示',
// content: res.data.message,
// confirmColor: '#118EDE',
// showCancel: false,
// success: function (res) {
// if (res.confirm) {
// //console.log('用户点击确定')
// }
// }
// });
}
}
obj.fail = function (res) {
//失败
// console.log("失败了·····"+res);
// setTimeout(function () {
// dd.httpRequest.hideLoading();
// }, 100);
// dd.httpRequest.showToast({
// title: '服务器暂时无法连接',
// icon: 'loading',
// duration: 2000
// })
dd.alert('fail',JSON.stringify(res))
reject(res)
}
fn(obj)
})
}
}
//无论promise对象最后状态如何都会执行
Promise.prototype.finally = function (callback) {
let P = this.constructor;
return this.then(
value => P.resolve(callback()).then(() => value),
reason => P.reject(callback()).then(() => { throw reason })
);
};
