Verification code either human flesh or machine recognition, machine identification to be based on the characteristics of the verification code to do processing, not so simple. Human flesh. Make an input submission and bring a cookie.

There is a verification code to do the simulation login too troublesome, to identify the verification code. As long as the other side to change a complex, there is no way.

I'm going to human flesh. Input, the verification code has been taken, and now returns an object moved to here at post.

The set up is really gone,
Now that's bad Request (Invalid number), what's the problem?

The number you passed in is not legal, see if someone let you enter the number, you enter other content.

It's best to post your code analysis.

After analysis, the actual login address should be 210.44.176.133, and then redirected to such address 210.44.176.133/(0QUS0S55GB1OJP45N2H0SR55)/ Default2.aspx, the middle brackets are randomly different each time, now how should I get this redirect address?
This is my way of writing.

function Curl_get_url () {$cookie _file=tempnam ('./ck ', ' Cookie '); $ch = Curl_init ("http://210.44.176.133"); curl_ Setopt ($ch, Curlopt_ssl_verifyhost, 1); curl_setopt ($ch, Curlopt_ssl_verifypeer, false); curl_setopt ($ch, Curlopt_ Returntransfer, 1); curl_setopt ($ch, curlopt_followlocation,true); curl_setopt ($ch, Curlopt_cookiejar, $cookie _file) ; curl_setopt ($ch, curlopt_maxredirs); $data = Curl_exec ($ch);//Run Curlcurl_close ($ch); return $data;}

You use the Get method, the general login should be the Post method

Your address is an intranet address and cannot be tested.
You can only start debugging yourself.
