Question

我的代码如下所示。我正在尝试使用eBay对用户进行身份验证，以便能够获取访问令牌。在将用户重定向回我的重定向URL以使用访问令牌交换代码时，我收到错误：

HTTP / 1.1 100继续HTTP / 1.1 400错误请求内容长度：109 Cneonction：close日期：星期四，2017年3月2日06:47:51 GMT RlogId： t6ldssk％28ciudbq％60anng％7Fu2h％3F％3Cwk％7Difvqn * 2％3D％3F％3E505-15a8dc659e6-0xf3 Set-Cookie：ebay =％5Esbf％3D％23％5E; Domain = .ebay.com; Path = / X-EBAY-C-REQUEST-ID：ri = v22kQg9yaBLq，rci = 2FDiyansIYnkONQC X-EBAY-C-VERSION：1.0.0 X-EBAY-REQUEST-ID： 15a8dc658f8.a0968eb.5f6ef.fff87b7e！[] Content-Type：application / json 连接：保持活力 {＆＃34;错误＆＃34;：＆＃34; INVALID_REQUEST＆＃34;＆＃34; ERROR_DESCRIPTION＆＃34;：＆＃34;＆＃39;授权＆＃39;是错过了标题：＆＃34;，＆＃34; error_uri＆＃34;：null}

我的POST请求有什么问题？

$auth_code = $_GET['code'];
$client_id = "Client ID";
$client_secret = "Client Secret";
$redirect_uri = "RuName";
$headers = array (
    'Content-Type'  => 'application/x-www-form-urlencoded',
    'Authorization' => sprintf('Basic %s',base64_encode(sprintf('%s:%s', $client_id, $client_secret)))
);
$apiURL = "https://api.sandbox.ebay.com/identity/v1/oauth2/token";
$urlParams = array (
        "grant_type" => "authorization_code",
        "code" => urlencode($auth_code),
        "redirect_uri" => $redirect_uri
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Should be removed on production
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_HEADER, true );

curl_setopt($ch, CURLOPT_URL, $apiURL);
curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers = array ('Authorization' => sprintf('Basic %s',base64_encode(sprintf('%s:%s', $client_id, $client_secret))),'Content-Type'  => 'application/x-www-form-urlencoded') );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $urlParams );

$resp = curl_exec ( $ch );
curl_close ( $ch );

print_r ( $resp );

Answer 1

您的代码存在两个小问题。第一个是CURLOPT_HTTPHEADER需要一个字符串数组而不是一个关联数组。

$headers = array (
    'Content-Type: application/x-www-form-urlencoded',
    'Authorization: '.sprintf('Basic %s',base64_encode(sprintf('%s:%s', $client_id, $client_secret)))
);

第二个是如何处理PHP处理CURLOPT_POSTFIELDS选项。正如documentation中所述。

将数组传递给CURLOPT_POSTFIELDS会将数据编码为 multipart / form-data，传递URL编码的字符串将进行编码数据为application / x-www-form-urlencoded。

由于eBay API要求正文为application/x-www-form-urlencoded，因此您需要传入字符串。您可以使用数组通过将其传递给http_build_query来构建此字符串。

$urlParams = http_build_query(array (
        "grant_type" => "authorization_code",
        "code" => $auth_code,
        "redirect_uri" => $redirect_uri
));

我还建议Postman测试向eBay发出API请求。其中一个功能是它还将为您创建PHP卷曲代码。下面的代码改编自Postman创建的代码。

<?php

$clientID = '<YOUR EBAY APP ID>';
$clientSecret = '<YOUR EBAY CERT ID>';
$ruName = '<YOUR EBAY RUNAME>';
$authCode = '<AUTH CODE>';

$url = 'https://api.sandbox.ebay.com/identity/v1/oauth2/token';

$headers = [
    'Content-Type: application/x-www-form-urlencoded',
    'Authorization: Basic '.base64_encode($clientID.':'.$clientSecret)
];

$body = http_build_query([
    'grant_type'   => 'authorization_code',
    'code'         => $authCode,
    'redirect_uri' => $ruName
]);

$curl = curl_init();

curl_setopt_array($curl, array(
    CURLOPT_URL            => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_CUSTOMREQUEST  => 'POST',
    CURLOPT_POSTFIELDS     => $body,
    CURLOPT_HTTPHEADER     => $headers
));

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

curl_close($curl);

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

使用eBay OAuth
