以上script将会直接return data:image/png;base64图片
回复讨论(解决方案)
请给出原始的 url
原始的url
https://vrl.lta.gov.sg/lta/vrl/action/captchaImg?FUNCTION_ID=F0501015ET
这个是我直接在browser输入url return的资料
你给的 url 有 js 错，什么都不显示
请给出正确的 url
hi xuzuning,
这个是我的url ： https://i-solutions.biz/readcontent/read.php
我要读取的url ： https://vrl.lta.gov.sg/lta/vrl/action/pubfunc?ID=EnquireTransferFee
读取captcha的url ： https://vrl.lta.gov.sg/lta/vrl/action/captchaImg?FUNCTION_ID=F0501015ET
你会看到当你直接browser captcha url的时候会出现js error：
Uncaught TypeError: Cannot read property 'length' of undefined
原因如下： windowID no match
if(k&&(l=k.parent.top.frames.vrlWindowID)&&226786===l.windowID)
有几个问题不明白的是
做法 1.：
$b = file_get_contents("https://vrl.lta.gov.sg/lta/vrl/action/captchaImg?FUNCTION_ID=F0501015ET");
echo $b;
显示
＊小弟不明白为什么会return这些乱码而不是像我在browser那样return js回来？
做法 2.：
在browser直接输入captcha url， 然后我把return回来的js ，
把 if(k&&(l=k.parent.top.frames.vrlWindowID)&&226786===l.windowID) 换成 if(1==1)
echo出来 就可以直接显示 base64图片
