Walmart.io身份验证问题-无法对请求中的身份验证进行身份验证 [英] Walmart.io authentication issue - Could not authenticate in-request, auth signature
问题描述
我正在尝试与Walmart.io API链接以从其资源中获取一些数据.但是我被困在第一阶段.
I am trying to link up with Walmart.io API to get some data from their resources. But I am stuck up in the first phase.
根据Walmart.io快速入门文档( https://walmart.io/docs/affiliate/quick-start-guide ),我应该按照以下步骤操作:
According to Walmart.io Quick Start Doc (https://walmart.io/docs/affiliate/quick-start-guide) I am supposed to follow following steps:
- 使用Walmart.io创建帐户
- 为Web应用程序创建应用程序
- 生成证书(根据他们的指南,应该有一些功能可以自动生成证书,但我没有找到它)
- 将公钥上传到应用程序
- 我们将获得消费者ID和密钥版本,并可以使用该版本和私钥进行请求.我们还需要添加包括签名和时间戳在内的其他标头.
所以,我做了所有事情,但仍然无法正常工作.
So, I did everything, but it still isn't working.
我正在按照他们的建议使用Open SSL生成私钥和公钥: https://walmart.io/key-tutorial 我尝试避免使用-des3,这样它也不会要求我输入密码,但这也不起作用.
I am using Open SSL to generate private and public key as suggested by them: https://walmart.io/key-tutorial I tried avoiding -des3 so that it doesn't ask me for passphrase too, but it didn't work either.
这是我尝试过的脚本
curl --location --request GET 'https://developer.api.walmart.com/api-proxy/service/affil/product/v2/taxonomy' \
--header 'WM_SEC.KEY_VERSION: 2' \
--header 'WM_CONSUMER.ID: <Consumer_ID>' \
--header 'WM_CONSUMER.INTIMESTAMP: 1594389945813' \
--header 'WM_SEC.AUTH_SIGNATURE: W5PEHIew3LsnATk0zxJddeo416YEpMIjvk1b7lW9VMIZFx55erc/5df/FK9UtS5i48q057oASo0AX3SDd2hx+QSeyiX3FtLAgAgiZnGqQ6nJndySWgL5ih/GaUTXIC6dd048GFEZlC6axXdGoTWNzX9P0n/2DwLF9EtvMjdvjB1kum0z2xKz/lQGlvnjVkGK9sZdSUa5rfgxKSPi7ix+LRIJWYwt6mTKUlGz2vP1YjGcZ7gVwAs9o8iFC//0rHUWFwaEGrT0aZJtS7fvSFtKj5NRfemX4fwRO4cgBRxPWy9MRooQwXPmKxRP75PxHKTerv8X6HvRo0GdGut+2Krqxg==' \
我得到的答复是
{
"details": {
"Description": "Could not authenticate in-request, auth signature : Signature verification failed: affil-product, version: 2.0.0, env: prod",
"wm_svc.version": "2.0.0",
"wm_svc.name": "affil-product",
"wm_svc.env": "prod"
}
}
希望有人给我一些有关这个问题的见识.
Hope someone gives me some insight into this problem.
预先感谢
推荐答案
原来是生成签名的问题(这解释了为什么在更改脚本后它可以工作.
Turns out it was issue with generated Signature (That explains why it worked after I changed the script.
这是运行良好的脚本:
<?php
use GuzzleHttp\Psr7;
use GuzzleHttp\Exception\RequestException;
class Walmart{
private $host;
private $consumer_id;
private $private_key_file;
private $headers;
private $sec_key_version;
private $client;
private $options;
public function __construct($config){
$this->host = $config['host'];
$this->consumer_id = $config['consumer_id'];
$this->private_key_file = $config['private_key_file'];
$this->sec_key_version = $config['sec_key_version'];
$this->options = array();
$this->client = new GuzzleHttp\Client();
}
public function lookup_product($publisher_id='', $ids='', $upc='', $format='json'){
$this->load_options();
$url_params = array(
'format' => $format,
);
if($publisher_id){
$url_params['publisher_id'] = $publisher_id;
}
if($ids){
$url_params['ids'] = $ids;
}
if($upc){
$url_params['upc'] = $upc;
}
$query = http_build_query($url_params);
$url = $this->host . '/product/v2/items?'.$query;
try {
$res = $this->client->request('GET', $url, $this->options);
$body = $res->getBody();
if($res->getStatusCode() == 200){
return $this->response(false, json_decode($body, true));
}else{
return $this->response(array(
'title' => 'Unable to get products',
'stack' => $body,
));
}
} catch (RequestException $e) {
$err = Psr7\str($e->getRequest());
if ($e->hasResponse()) {
$err .= Psr7\str($e->getResponse());
}
return $this->response(array(
'title' => 'Unable to get products',
'stack' => $err,
));
}
}
private function load_options(){
$timestamp = time()*1000;
$this->options = array(
'debug' => (defined("DEBUG") && DEBUG) ? true: false,
'headers' => array(
'WM_SEC.KEY_VERSION' => $this->sec_key_version,
'WM_CONSUMER.ID' => $this->consumer_id,
'WM_CONSUMER.INTIMESTAMP' => $timestamp,
'WM_SEC.AUTH_SIGNATURE' => $this->get_signature($timestamp),
)
);
}
private function get_signature($timestamp){
$message = $this->consumer_id."\n".$timestamp."\n".$this->sec_key_version."\n";
$pkeyid = openssl_pkey_get_private("file://".$this->private_key_file);
openssl_sign($message, $signature, $pkeyid, OPENSSL_ALGO_SHA256);
$signature = base64_encode($signature);
openssl_free_key($pkeyid);
return $signature;
}
private function response($err, $data=false){
return array(
'error' => $err,
'data' => $data,
);
}
}
注意:它将 guzzlehttp/guzzle 库用于HTTP请求
Note: It uses guzzlehttp/guzzle library for HTTP Request
