我在 laravel 中调用 magento2 API。使用 curl，我得到了正确的响应，但我想使用 GuzzleHttp\Client 或 Zend\Http\Client 调用 API。如何使用这个调用我的 api，下面是我的 curl 代码 sn-p：

    $curl = curl_init();
    $data=array('username'=>$vendordata['merchant_name'],'password'=>$vendordata['password'],'customer'=>['email'=>$vendordata['email'],"firstname"=> $vendordata['firstname'], "lastname"=> $vendordata['lastname']],"addresses"=> ["region"=> $vendordata['address'], "region_id"=> 0],"default_shipping"=> true,"default_billing"=>true,"telephone"=>$vendordata['contact_number']);
    $postdata=json_encode($data);

    curl_setopt_array($curl, array(
        CURLOPT_URL => "http://10.10.10.7/magento2/rest/V1/customers",
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "POST",
        CURLOPT_POSTFIELDS => $postdata,
        CURLOPT_HTTPHEADER => array(
            "authorization: OAuth oauth_consumer_key=\"sganfgvr2naxwmh21jgi5ffijuci0207\",oauth_token=\"d16pdq1avr1rs7h9745rc0x6py65a2vt\",oauth_signature_method=\"HMAC-SHA1\",oauth_timestamp=\"1518006201\",oauth_nonce=\"4ghORA\",oauth_version=\"1.0\",oauth_signature=\"Ztq5ErznqvCl18GomWv0F55t5OA%3D\"",
            "cache-control: no-cache",
            "content-type: application/json",
            "postman-token: 5ec55151-3365-7ffc-a6a4-ce5fe5bc451f"
        ),
    ));

    $response = curl_exec($curl);
    $err = curl_error($curl);

    curl_close($curl);

    if ($err) {
        echo "cURL Error #:" . $err;
    } else {
        echo $response;
    }

【解决方案1】：

首先，打开终端并运行此命令安装 Guzzle

composer require guzzlehttp/guzzle

然后添加这些行以在特定控制器中包含 guzzle。

use GuzzleHttp\Exception\GuzzleException;
use GuzzleHttp\Client;

现在，创建一个您要运行的方法来调用 API 并放入以下代码

$client = new Client(); //GuzzleHttp\Client
$result = $client->post('your-request-uri', [
    'form_params' => [
        'sample-form-data' => 'value'
    ]
]);

就是这样！

文档很好地解释了这一点：https://github.com/guzzle/guzzle

这里是使用 guzzlehttp 代替 curl 时的完整代码

$client = new GuzzleHttp\Client();
$response = $client->request('POST', 'http://10.10.10.7/magento2/rest/V1/customers', array(
    headers' => [
        'Authorization' => 'OAuth oauth_consumer_key="sganfgvr2naxwmh21jgi5ffijuci0207",oauth_token="d16pdq1avr1rs7h9745rc0x6py65a2vt",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1518006201",oauth_nonce="4ghORA",oauth_version="1.0",oauth_signature="Ztq5ErznqvCl18GomWv0F55t5OA%3D',
        'Cache-Control' => 'no-cache',
        'Postman-Token' => '5ec55151-3365-7ffc-a6a4-ce5fe5bc451f'
    ],
    'json' => $postdata
));

您还必须在您的 laravel 项目中为 PSR-7 support 安装以下依赖项，并查看此 stackoverflow question 作为参考：

composer require symfony/psr-http-message-bridge
composer require zendframework/zend-diactoros

我收到此错误：400 Bad Request` 响应：{"message":"%fieldName 是必填字段。","parameters":{"fieldName":"customer"}}
尝试使用form_params 而不是json，正如@TharinduLucky 下面建议的那样

【解决方案3】：

这是由于您没有在 HTTP 标头 上将Content-Type 定义为application/json。请试试这个

$client = new GuzzleHttp\Client();
$response = $client->request('POST', 'http://10.10.10.7/magento2/rest/V1/customers', array(
    headers' => [
        'Content-Type'  => 'application/json',
        'Authorization' => 'OAuth oauth_consumer_key="sganfgvr2naxwmh21jgi5ffijuci0207",oauth_token="d16pdq1avr1rs7h9745rc0x6py65a2vt",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1518006201",oauth_nonce="4ghORA",oauth_version="1.0",oauth_signature="Ztq5ErznqvCl18GomWv0F55t5OA%3D',
        'Cache-Control' => 'no-cache',
        'Postman-Token' => '5ec55151-3365-7ffc-a6a4-ce5fe5bc451f'
    ],
    'json' => $postdata
));

别忘了使用 composer 加载依赖项

composer require symfony/psr-http-message-bridge
composer require zendframework/zend-diactoros
