get请求
function fetchGet(url, callback) {
// return callback(null, top250)
wx.request({
url: url,
header: { 'Content-Type': 'application/json' },
success (res) {
callback(null, res.data)
},
fail (e) {
console.error(e)
callback(e)
}
})
}
post请求
function fetchPost(url, data, callback) {
wx.request({
method: 'POST',
url: url,
data: data,
success (res) {
callback(null, res.data)
},
fail (e) {
console.error(e)
callback(e)
}
})
}
下拉刷新：
getData: function() {
var that = this;
var tab = that.data.tab;
var page = that.data.page;
var limit = that.data.limit;
var ApiUrl = Api.topics +'?tab='+ tab +'&page='+ page +'&limit='+ limit;
that.setData({ hidden: false });
Api.fetchGet(ApiUrl, (err, res) => {
//更新数据
that.setData({
postsList: that.data.postsList.concat(res.data.map(function (item) {
item.last_reply_at = util.getDateDiff(new Date(item.last_reply_at));
return item;
}))
});
setTimeout(function () {
that.setData({ hidden: true });
}, 300);
})
}
上拉加载：
lower: function() {
console.log('滑动底部加载', new Date());
var that = this;
that.setData({
page: that.data.page + 1
});
if (that.data.tab !== 'all') {
this.getData({tab: that.data.tab, page: that.data.page});
} else {
this.getData({page: that.data.page});
}
}
})
