What should I do if a 403 error occurs in PHP Curl? curl error solution

ECURL_SETOPT ($ this-& gt; msh, curlopt_httpproxytunnel, true); There is no detailed explanation in the HP document, However, there is a detailed explanation in man curl. Both are proxies. proxytunnel (-p parameter) allows other protocols to be transmitted through the http proxy, while proxy (-x parameter) can only use the http protocol. So I guess that Google Baidu's server is at odds with curl's proxytunnel, so 403 is returned. After disabling the first sentence of the above two lines of code, curl access returns to normal.

Copy code

$ curl --version

Copy code

$ curl --version

Copy code

curl_setopt($ch, CURLOPT_NOBODY, true);

and you need to follow the settings:

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');

Otherwise, a 403 error will be returned because the http server does not allow the HEAD command.
