php - 如何使用 guzzle post 方法发送变量

Question

我有一个 API，我需要向它发送一些数据，我正在使用 guzzle 来处理它，所以这是我的代码:

$amount = $request->get('amount');
    $client = new \GuzzleHttp\Client();
    $requestapi = $client->post('http://192.168.150.16:7585/api/v1/Transaction/GetTransactionNumber', [
        'headers' => ['Content-Type' => 'application/json'],
        'body' => '{
        "Amount":"i want to send $amount here",
        "something":"1",
        "Description":"desc",
        }'
    ]);

所以一切都很好，正在发送静态数据，但我想知道如何发送变量。

Answer 1

您可以像这样在 form_params 参数中绑定(bind)数据

$client = new \GuzzleHttp\Client();
$amount = $request->get('amount');
$requestapi = $client->post('http://192.168.150.16:7585/api/v1/Transaction/GetTransactionNumber', [
                   'form_params' => [
                        "Amount" => "i want to send $amount here",
                        "something" => "1",
                        "Description" => "desc",
                   ]
             ]);

希望这对你有用。
