API 端点链接在 Postman 中有效，但在带有 ActiveResource 的 Ruby on Rails 中无效答案

【问题标题】：API endpoint link is working in Postman but not in Ruby on Rails with ActiveResourceAPI 端点链接在 Postman 中有效，但在带有 ActiveResource 的 Ruby on Rails 中无效
【发布时间】：2020-06-18 16:04:30
【问题描述】：

我正在开发 Ruby on Rails 应用程序，该应用程序需要通过 GET 请求访问外部 API。请求需要随请求一起发送一些参数。我使用 Activeresource gem 来访问 API。 API 请求在 Postman 中运行良好并提供了预期的记录，但在 Rails 应用程序中给了我 400 错误。

以下是代码

class PayRunEmploymentHeroBase < ActiveResource::Base
  self.site = "https://api.yourpayroll.com.au"
  self.user = ENV['EMPLOYMENT_HERO_USERNAME']
  self.element_name = ""
  self.include_format_in_path = false
  self.prefix = "/api/v2/business/:business_id/payrun?$filter=DateFinalised gt datetime':finalised_date'"
end

我在此处粘贴从 Rails 应用程序访问链接时出现 400 错误的详细信息。

2.3.0 :006 > PayRunEmploymentHeroBase.find(:all, params: {:business_id => business_id, :finalised_date =>  finalised_date})

我还附上了一张来自 Rails 应用程序的结果图片

【问题讨论】：

您能否在邮递员中提供请求标头和正文（如果存在）？
嗨，@KSDPutra 我已经用一张在 Postman 中显示标题的图像更新了请求。我目前没有遇到授权问题，因为我有其他工作正常的请求。我认为这个问题与过滤器参数有关。

标签： ruby-on-rails rest api postman activeresource

【解决方案1】：

您似乎没有使用 Rails 应用程序进行身份验证。而且我确定您已经在 Postman 中设置了身份验证用户名/密码。

将self.password = "password"（使用您自己的密码）设置为PayRunEmploymentHeroBase，它将起作用。

更新：其实是你的url没有编码，这样做就可以解决问题了：

self.prefix = "/api/v2/business/:business_id/payrun?$filter=" + URI::encode("DateFinalised gt datetime':finalised_date'")

【讨论】：

您好 Kien，我没有任何授权问题，因为我能够获得其他 API 链接的结果。由于我在用户名中提供了 API 密钥，所以我们不需要用户名和密码。
嗨@cvibha，很抱歉它不起作用。我看到了你的截图，希望 api 密钥不是真实的，否则你需要审查它。也许问题出在过滤器上，您可以尝试对其进行编码吗？ self.prefix = URI.encode_www_form_component("/api/v2/business/:business_id/payrun?$filter=DateFinalised gt datetime':finalised_date'") 看看是否有效
API 密钥是真正的 Kien，因为我能够让其他 API 请求正常工作。我尝试使用您提供的编码，但它也不起作用。在对请求进行编码后，我收到了以下 URL。 "api.yourpayroll.com.au:443%2Fapi%2Fv2%2Fbusiness%2F%3Abusiness_…"
抱歉，对整个部分进行编码不好。我只对过滤器参数进行了编码测试，但它没有给我 400：self.prefix = "/api/v2/business/:business_id/payrun?$filter=" + URI.encode_www_form_component("DateFinalised gt datetime':finalised_date'")。这使得最终的 url 是https://api.yourpayroll.com.au:443/api/v2/business/48058/payrun?$filter=DateFinalised+gt+datetime%272017-11-16%27。请尝试让我知道
@cvibha 500 表示服务器出现异常，无法处理请求，优于 400（客户端错误）。我认为我推荐的编码方法不起作用。请尝试URI::encode：像这样：self.prefix = "/api/v2/business/:business_id/payrun?$filter=" + URI::encode("DateFinalised gt datetime':finalised_date'")，这使得api.yourpayroll.com.au:443/api/v2/business/48058/…'。请试一试
