<view class="infoRow marginB20" wx:for="{{newList}}" wx:key="key" wx:for-index="idx" wx:for-item="vo">

      <view class="n-list">
        <navigator url="../new_content/new_content?id={{vo.id}}">
          <text class="n-t1">{{vo.title}}</text>

  这里传的{{vo.id}} 应该不需要多解释 就是文章的id

  /**
   * 生命周期函数--监听页面加载
   */ 这里是获得渲染过来的id 也就是 ?id={{vo.id}
  onLoad: function (options) {
    let that = this;
    let newid = options.id;
    that.setData({
      newid: newid 
    })

    var url = app.api.getContent + "&p1=news" + "&p2=" + newid;
    wx.request({
      url: url,
      data: {},
      method:'get',
      success: function (res) {
        var obj = res.data.result[0];
        console.log(obj)
        var content = obj.content;
        if (content) {
          WxParse.wxParse('content', 'html', content, that, 0);
        }

        that.setData({
          viewDetail: obj
        })
      }
    })
app.api.getContent + "&p1=news" + "&p2=" + newid;  这个url自己返回 你有自己的接口  直接把你获得的id拼接进去就好了
