根據

the manual,

The body option is used to control the body of an entity enclosing

request (e.g., PUT, POST, PATCH).

記錄的put’ing方法是：

$client = new GuzzleHttp\Client();

$client->put('http://httpbin.org', [

'headers' => ['X-Foo' => 'Bar'],

'body' => [

'field' => 'abc',

'other_field' => '123'

],

'allow_redirects' => false,

'timeout' => 5

]);

根據您的評論：

您缺少createRequest函數的第三個參數 – 構成post或put數據的鍵/值對數組：

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