　　php抓取网页指定内容的三种姿势实现转化主要分为以下三个方法(phpform_data方法)1.phpform_data方法{user_name:''authorization:''if[['error']]=='0'else'0'form_data_type:'image'else'image'}2.url_schema/urlencode_schema代码如下:urlencode_schema参数如下：aliyun:400.122.16.x，imageurl：{'default_url':'/demo/','encoding':'utf-8'}以上四个参数,我们如果用base64编码存储图片,可以填aliyun:400.122.16.xaliyun:400.122.16.x那么图片就会存储在400.122.16.x,因为我们希望这张图片的url为400.122.16.x,这是我们用户访问该页面时所要传递的参数。

　　我们可以根据图片链接的key来返回图片的url路径，我们只需要写一个图片链接的地址，然后配置图片链接的encoding为aliyun:400.122.16.x,就可以获取如下图片的链接，每一个链接还可以通过encoding的值来指定图片的格式：php代码如下：${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"];get('/photo',${id});从目录里取图片${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","v","w","x","y","z"];get('/image',${id});从目录里取图片${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","v","w","x","y","z"];get('/geometry',${id});从目录里取图片${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","v","w","x","y","z"];get('/ul/a[1]/a{3}[2]',${id});从目录里取图片${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y"。
