js文件onLoad方法内添加:

var that = this
    wx.request({
        url: 'https://qq.ytecn.com/zb/',
        success: function (res) {
        that.setData({
        zhihu: res.data
        })
    }
})

wxml调用方法:

<view class="container log-list">
<block wx:for="{{zhihu.data}}" wx:for-item="log">
<text class="log-item">{{index + 1}}. {{log.title}}</text>
</block>
</view>
