now we need to do a project that embeds the login page of other people"s websites, and then this login box is under our own page. We can"t see it when the CAPTCHA appears, and now we need to get its CAPTCHA. Show it to our own page. This is the URL of the CAPTCHA http://api.sceea.cn/Handler/V.. Png, is dynamic. As long as it is clicked or refreshed, it will change. The verification code filled in during verification is different from the actual one, so it cannot pass the verification
. 
is mainly about session. The answers to the CAPTCHA are usually stored in session, which can be compared with the developer's tools. Whether the session_id when obtaining the verification code is the same as the session_id when submitting the verification code, it must be the error of the verification code reported. This is similar to a project that separates the front and rear ends.
are you going to get the CAPTCHA returned by others and verify it with your text box? Is that what you mean? /
Is the return ofjust a picture? Then we can only deal with the picture and extract the text, which is not accurate enough
get the image object and change it to base64
