Php curl implements http and https requests. phpcurlhttps request_php tutorial

Php curl implements http and https requests, namely, phpcurlhttps requests. Php curl implements http and https requests. This document describes how php curl implements http and https requests. Php curl implements http and https requests.

This article describes how to implement http and https requests using php curl. The details are as follows:

Generally, the php curl function Group can help us pretend to be an adult and capture the website. here are two examples: accessing an http webpage and accessing an https webpage, let's take a look.

Each time you use curl, you always need to check a bunch of data.
Now we can save a few frequently used sentences, saving every time we go to Google.

Common curl requests:

The code is as follows:

$ Url = 'http: // www.bkjia.com ';
$ Curl = curl_init ();
Curl_setopt ($ curl, CURLOPT_URL, $ url );
Curl_setopt ($ curl, CURLOPT_HEADER, 1 );
Curl_setopt ($ curl, CURLOPT_RETURNTRANSFER, 1 );
$ Data = curl_exec ($ curl );
Curl_close ($ curl );
Var_dump ($ data );

Use curl to request HTTPS:

The code is as follows:

$ Url = 'https: // www.jb51.net ';
$ Curl = curl_init ();
Curl_setopt ($ curl, CURLOPT_URL, $ url );
Curl_setopt ($ curl, CURLOPT_HEADER, 1 );
Curl_setopt ($ curl, CURLOPT_RETURNTRANSFER, 1 );
Curl_setopt ($ curl, CURLOPT_SSL_VERIFYPEER, false); // This is the focus.
$ Data = curl_exec ($ curl );
Curl_close ($ curl );
Var_dump ($ data );

Note:

When requesting https data, the certificate is required. at this time, the following two parameters are added to avoid ssl certificate check.

The code is as follows:

Curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https requests do not verify the certificate and hosts
Curl_setopt ($ ch, CURLOPT_SSL_VERIFYHOST, FALSE );

I hope this article will help you with PHP programming.

PHP uses CURL to submit POST data to https websites

The error message is that the https protocol is not supported.
Stackoverflow.com/..-https has saved me. Thank God.
There are spaces in front of https.

For https websites, you can use php curl to simulate get and post. can you get the returned value?

Yes.
CURLOPT_PROTOCOLS
The bitfield of CURLPROTO _ * indicates. If enabled, the bitfield value limits the protocols that libcurl can use during transmission. This will allow you to support many protocols when compiling libcurl, but the restriction is only a subset of them that are allowed to be used. By default, libcurl uses all protocols supported by libcurl. See CURLOPT_REDIR_PROTOCOLS.
Available protocol options: CURLPROTO_HTTP, CURLPROTO_HTTPS, CURLPROTO_FTP, protocol, CURLPROTO_SCP, protocol, CURLPROTO_TELNET, CURLPROTO_LDAP, CURLPROTO_LDAPS, protocol, CURLPROTO_FILE, protocol, CURLPROTO_ALL

By the way, you can obtain the returned value.
