微信小程序调用PHP后台接口,解析纯html文本,效果图片预览
1、微信js动态传参:
wx.request({ url: 'https://m.****.com/index.php/Home/Xiaoxxf/activity_detail?a_id='+options.id,//含富文本html data: { is_detail:1 }, method: 'GET', // OPTIONS, GET, HEAD, POST, PUT, DELETe, TRACE, ConNECT header: { 'Content-Type': 'application/json' }, success: function (res) { that.setData({ Article: res.data //一维数组json编码后对象 }) var article = that.data.Article; console.log("article = " + article); WxParse.wxParse('article', 'html', article, that, 5); console.log(res.data); }, fail: function (res) { }, complete: function (res) { }, }),
其中,options.id是由前一个wxml页面动态传过来的参数。
2、wxParse插件使用:
github地址: https://github.com/icindy/wxParse,版本0.2
解决问题:微信小程序富文本html、md解析组件
1)复制wxParse文件夹到pages同目录
2)在wxml页面引入模板代码:
<import src=http://www.shancun.net/skin/default/image/nopic.gif>富文本html框内容:<template is="wxParse" data="{{wxParsedata:article.nodes}}"/>
3)在js的page({})里面引入执行文件
// 引入wxParse.js解析文件var WxParse = require('../../wxParse/wxParse.js');page({...})4)在js文件里面解析获取的纯html字符串,注意:这里必须得是字符串(如:'<div>2112</div>'),如果有''就要去掉。
示例代码:wx.request({ url: 'https://m.*****.com/index.php/Home/Xiaoxxf/activity_detail?a_id='+options.id,//含富文本html data: { is_detail:1 }, method: 'GET', header: { 'Content-Type': 'application/json' }, success: function (res) { that.setData({ Article: res.data //一维数组json编码后对象,全部数据 }) var article = that.data.Article; console.log("article = " + article); WxParse.wxParse('article', 'html', article, that, 5); console.log(res.data); }, fail: function (res) { }, complete: function (res) { }, })3、PHP后台接口(本接口仅做示例,未做安全和过滤校验):
public function activity_detail(){ $is_detail = I('is_detail'); if(!empty($is_detail)){ //富文本html文章 $a_id = I('a_id'); $a_id = intval($a_id)?$a_id:0; if(empty($a_id)){ $data['code'] = 500; $data['msg'] = '抱歉,文章已失效'; echo json_encode($data); }else{ //获取结果为指定字段的二维数组,下面截取一维数组 $data =D()->query("select act_detail from xxf_witkey_activity where is_show = 1 and a_id = ".$a_id." order by a_id desc"); //var_dump($data);return ; $data = $data[0]; $data = stripslashes(implode(',', $data)); $data = str_replace(array('src=http://www.shancun.net/skin/default/image/nopic.gif','src=http://www.shancun.net/skin/default/image/nopic.gif'),array('src="http://www.xxiangfang.com/data/uploads/','src="http://www.xxiangfang.com/data/uploads/'),$data); echo $data; } }else{ //普通字段(封面、特色、活动名称) $a_id = intval(I('GET.a_id')); $data =D()->query("select a_id,act_name,pic_url,introduction from xxf_witkey_activity where is_show = 1 and a_id = ".$a_id." order by a_id desc"); if($data) $data = $data[0]; echo json_encode($data); } }
