php uses guzzule 6 to send HTTP requests

guzzle was upgraded to version 6 unknowingly. After the upgrade, the usage was different from the original 3.*. I was confused when I read the documentation. It took me a long time to find the usage from the documentation:
POST

<code><span>$response</span> = <span>$client</span>->request(<span>'POST'</span>, <span>'http://httpbin.org/post'</span>, [
    <span>'form_params'</span> => [
        <span>'field_name'</span> => <span>'abc'</span>,
        <span>'other_field'</span> => <span>'123'</span>,
        <span>'nested_field'</span> => [
            <span>'nested'</span> => <span>'hello'</span>
        ]
    ]
]);
<span>$result</span> = <span>$response</span>->getBody();</code>

GET

<code><span>$client</span><span>=</span><span>new</span> Client();
<span>$res</span><span>=</span><span>$client</span><span>-></span>request(<span>'GET'</span>, <span>$url</span><span>.</span><span>"?param1=1&param2=9"</span>);
<span>$result</span><span>=</span><span>$res</span><span>-></span>getBody();</code>

To be fair, it’s quite convenient.

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above introduces how to use guzzule 6 to send HTTP requests in PHP, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
