The above is a basic curl access method. Because IPv6 needs to be used here, corresponding options have been added. I believe you can see clearly that the options that are often used at ordinary times appear above, so you can choose according to your needs.

The status code prompt 405/Method Not Allowed indicates that the requested method is not supported. This error is not common.

This error occurs because curl defaults to post for committed access, post mode has no authority under such domain names. For example, this kind of problem occurred when testing www. amazon. cn, but it can be accessed normally after being modified to get mode and adding header header. Personally, it is speculated that Amazon basically adopts get mode, which will be considered as artificial click and shielded post accordingly.

The following code has been added to this:

// Settings Header Head 
$header[] = "Accept: application/json";
$header[] = "Accept-Encoding: gzip";
// Add HTTP header The head adopts compression and GET Mode request 
curl_setopt( $ch, CURLOPT_HTTPHEADER, $header );
curl_setopt($ch,CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');

The command line takes the form of:

curl -v www.amazon.cn
