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-Encoding:gzip, deflate, sdch
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

const METHOD_POST = 'POST';
const METHOD_DELETE = 'DELETE';

self::METHOD_POST,
self::METHOD_DELETE

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())
{

}
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($decodedResult['success']))
{
echo "Invalid Response";
return;
}
if (!$decodedResult['success'])
{
echo "<h2>No Success</h2>";
echo "<p>" . $decodedResult['message'] . "</p>";
return;
}
echo "<h2>Success</h2>";
if (isset($decodedResult['data']))
{

}
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。

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)
