eBay oauth 令牌和刷新令牌

Question

几天来一直在努力使用 eBay 令牌身份验证。我发现很难理解如何获取新令牌，在注册开发人员计划帐户后，我请求了密钥集并获得了它们，之后我授予对 Auth'n'Auth 令牌的访问权限，该令牌承诺持续 18 个月，是的，该代币仅适用于交易、购物和寻找 api。

但是当您需要执行购买、销售和商务时 api，您必须获得 oauth 令牌。您可以执行所谓的 "Single User app" 样式并从用户令牌工具登录 oauth，并获得 2 小时到期的 oauth。

稍后令牌过期，您有点失去对上述 api 的访问权限。我尝试从 Trading > Get session ID、Trading > Fetch token 获取令牌，但在向 Fetch token 提供会话 ID 后，它说："The end user has not completed Auth & Auth sign in flow." 虽然有 18 个月的有效令牌，但它一直返回此错误。

是否有关于此的任何示例文章，任何人都可能读过或写过？

Answer 1

这详细介绍了“新销售”API 的 OAuth 流程，而不是 auth 'n' auth 或遗留交易 API。它也适用于沙箱，尽管生产过程是相同的。

您的困惑并非没有根据。我自己在这个 API 流程中的经历，以及大部分 official dev forums 中的经历，都让我倍感压力。下面详细说明了生成 oauth 不相关 的过程，无论您是连接到单个、专用帐户还是多个用户帐户。

official guide 确实解释了整个过程，所以我犹豫要不要在这里重新创建整个指南。不过，我可以提供一个摘要（我建议在尝试通过您的应用程序之前使用 Postman 遵循以下内容）：

从 here 收集您的客户端 ID 和客户端密码（不要公开分享这些）
通过单击 “通过您的应用程序从 eBay 获取令牌”从 here 生成一个 RuName（重定向 URL 名称）并填写表格。此表单用于构建登录页面的外观，用户将被重定向以允许您的应用程序访问他们的帐户。然后，RuName 将直接出现在列 header " RuName (eBay Redirect URL name)"
下方
收集您需要的范围列表。每个 API 端点都需要一个具有适当范围权限的 OAuth 令牌。例如，Create or Replace Inventory Item 端点需要 https://api.ebay.com/oauth/api_scope/sell.inventory 范围。弄清楚您将需要哪些端点，然后转到每个端点的 API 文档并找到范围部分。

get 请求现在看起来像这样：

`https://signin.sandbox.ebay.com/authorize?
client_id=<your-client-id-value>&
redirect_uri=<your-RuName-value>&
response_type=code&
scope=https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2Fsell.account%20
https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2Fsell.inventory`

还建议您添加一个state 查询字符串，为了便于使用我省略了它，但您应该研究what they are 以及为什么它们被推荐用于 OAuth。

浏览器中的 URL 会将您重定向到 sign-in 页面，以便用户允许您的应用程序访问他们的帐户，但仅限于 URL。从 PHP curl 请求中转储，您将获得重定向 URL 本身。 重要提示：即使您的应用程序只有 一个用户，也需要最终用户的签名。例如，您有一个面向客户的 e-commerce 网站，您希望将他们的产品发送到他们的单一 eBay 帐户。您仍然需要至少每 18 个月执行一次此过程（很快就会找出原因）。
用户登录并确认后，浏览器将显示“您现在可以关闭此window”页面。下一步需要的授权码在本页的 URL 中作为 code 查询字符串。如果您正在为多个用户开发应用程序并计划实际让他们在此页面上登录，那么您需要配置您的应用程序以获取确认响应，这将是前面提到的 URL，并从中提取代码.这段代码非常short-lived。如果您通过浏览器手动检索它，则需要快速完成后续步骤。

您现在需要向 https://api.sandbox.ebay.com/identity/v1/oauth2/token 执行 POST 请求。请参阅以下结构：

HTTP method:   POST
URL (Sandbox): https://api.sandbox.ebay.com/identity/v1/oauth2/token

HTTP headers:
Content-Type = application/x-www-form-urlencoded
Authorization = Basic <B64-encoded-oauth-credentials> (A base64-encoded value made from your client ID and client secret, separated by colon. For example, in PHP you could generate it with: `base64_encode ("fakeclientid123:fakeclientsecret123")`)

Request body (wrapped for readability):
grant_type=authorization_code& (literally the string "authorization_code")
code=<authorization-code-value>& (code retreived in previous step)
redirect_uri=<RuName-value> (same RuName as earlier)

如果成功，此请求将 return 如下所示：

{
    "access_token": "v^1.1#i^1#p^3#r^1...XzMjRV4xMjg0",
    "token_type": "User token",
    "expires_in": 7200,
    "refresh_token": "v^1.1#i^1#p^3#r^1...zYjRV4xMjg0",
    "refresh_token_expires_in": 47304000
  }

这是我们想要的 oauth 令牌，它将持续 2 小时。第二个令牌是刷新令牌，将持续约 18 个月。请妥善保管此令牌，不要共享它，也不要在您的应用中 hard-code。从这一点开始，您的应用程序应该使用此令牌执行刷新调用，以便在需要时获得新的 oauth。一旦 18 个月到期，或者如果用户再次执行“允许访问”程序，您将需要执行上述所有操作以生成新的刷新令牌。假设 API 到那时还没有改变。

值得注意的是，18 个月的生命周期不是 OAuth 刷新的正常程序，通常每次使用旧令牌时都应该 return 一个新的刷新令牌。

要刷新 oauth：

  HTTP method:   POST
  URL (Sandbox): https://api.sandbox.ebay.com/identity/v1/oauth2/token

  HTTP headers:
    Content-Type = application/x-www-form-urlencoded
    Authorization = Basic <B64-encoded-oauth-credentials>

   Request body (wrapped for readability):
      grant_type=refresh_token&
      refresh_token=<your-refresh-token-value>&
      scope=https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2Fsell.account%20
      https%3A%2F%2Fapi.ebay.com%2Foauth%2Fapi_scope%2Fsell.inventory

希望对您有所帮助！

Answer 2

对于那些遇到困难的人 - 确保您使用的是编码的代码/令牌。

我几乎失去了理智试图找出问题所在，因为 ebay returns 刷新令牌已解码

Answer 3

对于遇到困难的任何人，请注意第 4 步中的 URL 与 eBay 上给出的 URL 不同。 eBay 上的 URL 以 https://auth.sandbox.ebay.com/oauth2/authorize 开头，但步骤 4 中的 URL 以 https://signin.sandbox.ebay.com/authorize

开头

Answer 4

我发现上面@FullStackFool 的 post 非常有帮助。基于此，我构建了一个 class 从本地数据库获取当前令牌，在需要时刷新令牌，显示获取新刷新令牌的说明，或处理代码以生成新刷新令牌。

Class 是在 PHP 5.6 中编写的（抱歉 - 旧的内部订单管理系统），但可以轻松升级到 PHP 7 / Laravel 等

构造函数只采用一个可选值 - 这是 URL 字符串，当您验证/登录以获取新令牌时由 ebay 生成。如果将其输入构造函数，它将对其进行解析，获取 'code' 部分，然后获取新令牌并刷新令牌。

希望代码是不言自明的——我已经尽力对其进行了注释。希望其他人觉得这很有用。
