美好的一天，我是通过 PHP curl 进行这个 docusignapi 集成的新手，我想尝试这个集成。我已经从http://iodocs.docusign.com/APIWalkthrough/requestSignatureFromDocument复制了下面的代码，希望我可以轻松测试和理解集成的工作原理。但不幸的是，总是出现错误“调用webservice时出错，状态为：0”。我尝试了其他解决方法，例如将标头格式从 XML 更改为 JSON，但错误仍然出现。请帮忙。

    // Input your info here:
$integratorKey = 'XXXX-9999X9XX-X999-9999-99X9-9X9999X9XX9X';
$email = 'name@domain.com';
$password = 'samplepassword';
$name = 'Sender Full Name';

// construct the authentication header:
$header = "<DocuSignCredentials><Username>" . $email . "</Username><Password>" . $password . "</Password><IntegratorKey>" . $integratorKey . "</IntegratorKey></DocuSignCredentials>";
/////////////////////////////////////////////////////////////////////////////////////////////////
// STEP 1 - Login (to retrieve baseUrl and accountId)
/////////////////////////////////////////////////////////////////////////////////////////////////
$url = "https://demo.docusign.net/restapi/v2/login_information";
$curl = curl_init($url);

curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array("X-DocuSign-Authentication: $header"));
print_r(curl_getinfo($curl));
echo "<br/>";
$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ( $status != 200 ) {
    echo "error calling webservice, status is:" . $status;
    exit(-1);
}

$response = json_decode($json_response, true);
$accountId = $response["loginAccounts"][0]["accountId"];
$baseUrl = $response["loginAccounts"][0]["baseUrl"];
curl_close($curl);

//--- display results
echo "\naccountId = " . $accountId . "\nbaseUrl = " . $baseUrl . "\n";

                                            "documentId" => "1",
                                            "pageNumber" => "1"
                                         )
                                    )
                            )

    "X-DocuSign-Authentication: $header" )                                                                       
);

$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ( $status != 201 ) {
    echo "error calling webservice, status is:" . $status . "\nerror text is --> ";
    print_r($json_response); echo "\n";
    exit(-1);
}

$response = json_decode($json_response, true);
$envelopeId = $response["envelopeId"];

//--- display results
echo "Document is sent! Envelope ID = " . $envelopeId . "\n\n";

有没有可能我的集成密钥无效？如果是，有什么方法可以检查我的积分器密钥是否有效？在创建我的集成密钥时，我只是按照此链接http://www.docusign.com/developer-center/quick-start/first-api-call中的程序进行操作

我马上看不出代码有什么问题。每当根本没有返回任何状态时，它通常是可能导致此问题的三件事之一：

  1. 安全软件阻止您的请求通过。
  2. 防火墙阻止您的请求通过。
  3. 端口 443 因其他原因（2 或 3 除外）而关闭。

您是否有任何日志可以检查您的请求是否被拦截，无论是在软件级别还是硬件级别（如果您有硬件防火墙）？我会先检查这样的事情。
