请大大求解....
我用file_get_contents() return 以下图 ,请问有什么办法变成data:image/png;base64 图片?




如果我直接用browser直接输入那个url 将会return script

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
