Shopware REST Api - 无效或缺少身份验证

标签: php api rest curl shopware

我试图访问Shopware的REST API。我使用的是Shopware 5.1.3版。我正在使用documentation的代码。

我总是得到一个http代码400(无效或缺少身份验证)。

当我尝试通过谷歌浏览器访问API时,它在使用http身份验证登录后才能正常工作,因此凭据应该没问题。

我认为Chrome发送的身份验证标头与我使用PHP curl发送的标头不同。

使用Chrome:

Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8

Accept-Language:nl-NL,nl;q=0.8,en-US;q=0.6,en;q=0.4

使用PHP Curl

GET /api/articles? HTTP/1.1\r\n
Host: shopware.example.com\r\n
Authorization: Digest username="demo",realm="",nonce="806c9770a53bf2f82b87734a9d8eb98c",uri="/api/articles?",cnonce="60e6c8db046db8f4e63fece37e38f92e",nc=00000001,algorithm=MD5,response="299069d4659af386a4ec7058796267c2",qop="auth",opaque="d75db7b160fe72d1346d2bd1f67bfd10"\r\n
User-Agent: Shopware shopwareApiClient\r\n
Accept: */*\r\n
Content-Type: application/json; charset=utf-8\r\n
Content-Length: 2\r\n

额外的PHP curl指令以获取标头信息:

curl_setopt($this->cURL, CURLINFO_HEADER_OUT, true);
print_r(curl_getinfo($this->cURL, CURLINFO_HEADER_OUT ));

我使用的代码:

<?php

namespace App;

class shopwareApiClient
{

    const METHOD_GET = 'GET';
    const METHOD_PUT = 'PUT';
    const METHOD_POST = 'POST';
    const METHOD_DELETE = 'DELETE';

    protected $validMethods = array(
        self::METHOD_GET,
        self::METHOD_PUT,
        self::METHOD_POST,
        self::METHOD_DELETE
    );
    protected $apiUrl;
    protected $cURL;

    public function __construct($apiUrl, $username, $apiKey)
    {
        $this->apiUrl = rtrim($apiUrl, '/') . '/';
        //Initializes the cURL instance
        $this->cURL = curl_init();
        curl_setopt($this->cURL, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($this->cURL, CURLOPT_FOLLOWLOCATION, false);
        curl_setopt($this->cURL, CURLOPT_USERAGENT, 'Shopware shopwareApiClient');
        curl_setopt($this->cURL, CURLOPT_HTTPAUTH, CURLAUTH_DIGEST);
        curl_setopt($this->cURL, CURLOPT_USERPWD, $username . ':' . $apiKey);
        curl_setopt($this->cURL, CURLOPT_HTTPHEADER, array(
            'Content-Type: application/json; charset=utf-8',
        ));
        curl_setopt($this->cURL, CURLINFO_HEADER_OUT, true);
    }

    public function call($url, $method = self::METHOD_GET, $data = array(), $params = array())
    {
        if (!in_array($method, $this->validMethods))
        {
            throw new Exception('Invalid HTTP-Methode: ' . $method);
        }
        $queryString = '';
        if (!empty($params))
        {
            $queryString = http_build_query($params);
        }
        $url = rtrim($url, '?') . '?';
        $url = $this->apiUrl . $url . $queryString;
        $dataString = json_encode($data);
        curl_setopt($this->cURL, CURLOPT_URL, $url);
        curl_setopt($this->cURL, CURLOPT_CUSTOMREQUEST, $method);
        curl_setopt($this->cURL, CURLOPT_POSTFIELDS, $dataString);
        $result = curl_exec($this->cURL);
        dd(curl_getinfo($this->cURL, CURLINFO_HEADER_OUT ));
        $httpCode = curl_getinfo($this->cURL, CURLINFO_HTTP_CODE);
        return $this->prepareResponse($result, $httpCode);
    }

    public function get($url, $params = array())
    {
        return $this->call($url, self::METHOD_GET, array(), $params);
    }

    public function post($url, $data = array(), $params = array())
    {
        return $this->call($url, self::METHOD_POST, $data, $params);
    }

    public function put($url, $data = array(), $params = array())
    {
        return $this->call($url, self::METHOD_PUT, $data, $params);
    }

    public function delete($url, $params = array())
    {
        return $this->call($url, self::METHOD_DELETE, array(), $params);
    }

    protected function prepareResponse($result, $httpCode)
    {
        echo "<h2>HTTP: $httpCode</h2>";
        if (null === $decodedResult = json_decode($result, true))
        {
            $jsonErrors = array(
                JSON_ERROR_NONE => 'No error occurred',
                JSON_ERROR_DEPTH => 'The maximum stack depth has been reached',
                JSON_ERROR_CTRL_CHAR => 'Control character issue, maybe wrong encoded',
                JSON_ERROR_SYNTAX => 'Syntaxerror',
            );
            echo "<h2>Could not decode json</h2>";
            echo "json_last_error: " . $jsonErrors[json_last_error()];
            echo "<br>Raw:<br>";
            echo "<pre>" . print_r($result, true) . "</pre>";
            return;
        }
        if (!isset($decodedResult['success']))
        {
            echo "Invalid Response";
            return;

            return;
        }
        echo "<h2>Success</h2>";

        return $decodedResult;
    }
}

编辑:找到php bug report,其中说明PHP版本5.6及更高版本的PHP存在错误。我在Windows上使用XAMP。我将在linux上试一试,看看它是否有效。

答案 0 :(得分:4)

bug report是正确的。我在Windows上使用XAMP和PHP 5.6。

将我的PHP代码放在linux机器上之后,代码就可以了。

引用错误报告:

说明

     

尝试将curl_exec与摘要式身份验证一起使用无法正常工作。   运行测试脚本始终无法通过安全挑战。   使用浏览器或wget可以直接使用。

     

另外,尝试在我的另一台服务器上运行相同的测试,使用php 5.5.21的amazon linux工作,但是使用php 5.6.11的Windows 7 x64机器无效。

     

试图在几台Windows机器上使用CLI使用php 5.5或5.4运行测试导致了php可执行程序的完全粉碎。

     

似乎bug#69088是相关的,但这个bug也发生在linux(5.5)上。

     

测试脚本:

<?
$curl = curl_init();

$curl_options = [
    CURLOPT_HTTPAUTH => CURLAUTH_ANY,

    CURLOPT_USERPWD => 'test_user:password',
    CURLOPT_URL => 'http://test_user:password@httpbin.org/digest-auth/auth/user/password',
    CURLOPT_HEADER => true,
];
curl_setopt_array($curl, $curl_options);

curl_exec($curl);
curl_close($curl);
  

预期结果:

{
  "authenticated": true, 
  "user": "user"
}
     

实际结果:

"Authentication failed" (with header 401)

我的Apache 2.4.17(Win7 / 64上来自Apachelounge的Win32 / VC11)的PHP客户端/脚本和CalDAV / SabreDAV框架(也包括在Owncloud,Baikal等中)也有同样的问题。

     

我使用不同版本的PHP 5.6.x版本玩了一下,发现了以下内容:

     
      
  • php_curl.dll&lt; = v5.6.4 - 没问题
  •   
  • php_curl.dll v5.6.5 / v5.6.6 - 与Auth_Digest崩溃
  •   
  • php_curl.dll =&gt; v5.6.7 - Auth_Digest失败
  •   
     

该错误也出现在PHP 5.5发行版和PHP 5.4中(最后稳定的PHP_CURL.DLL我在v5.4.36中找到)
