How do I send parameters for a PUT request in Guzz

问题:

I have this code for sending parameters for a POST request, which works:

$client = new GuzzleHttp\Client();
$request = $client->createRequest('POST', 'http://example.com/test.php');
$body = $request->getBody();

$request->getBody()->replaceFields([
    'name' => 'Bob'
]);

However, when I change POST to PUT, I get this error:

Call to a member function replaceFields() on a non-object

This is because getBody is returning null.

Is it actually correct to send PUT parameters in the body? Or should I do it in the URL?

回答1:

According to the manual,

The body option is used to control the body of an entity enclosing request (e.g., PUT, POST, PATCH).

The documented method of put'ing is:

$client = new GuzzleHttp\Client();

$client->put('http://httpbin.org', [
    'headers'         => ['X-Foo' => 'Bar'],
    'body'            => [
        'field' => 'abc',
        'other_field' => '123'
    ],
    'allow_redirects' => false,
    'timeout'         => 5
]);

Edit

Based on your comment:

You are missing the third parameter of the createRequest function - an array of key/value pairs making up the post or put data:

$request = $client->createRequest('PUT', '/put', ['body' => ['foo' => 'bar']]);
