如何将 http 请求发送到 Stripe 而不是 curl 请求

Question

我可以成功向 Stripe API 发送 curl 请求，就像这样：

curl https://api.stripe.com/v1/customers?limit=3 
  -u sk_test_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx: 
  -G

如何使用Elixir依赖项：HTTPoison来发送HTTP请求？

Answer 1

HTTPoison模块具有发出HTTP GET请求的get函数。

您可以在iex中运行h HTTPoison.get以获取有用的帮助消息。

最好在

加载库的情况下启动iex，并使用各种值探索所需的函数，并检查返回或生成的数据。

在这种情况下，这样的事情应该让你开始：

url = "https://api.stripe.com/v1/customers?limit=3"
headers = [ {"Authorization", "Bearer " <> "sk_test_xxxxxxxxxxxxxxxxxxx"} ]
case HTTPoison.get(url, headers, []) do
  {:ok, %HTTPoison.Response{body: body, status_code: 200}} -> 
      # some data is returned
      "success body = " <> Poison.decode!(body)
  {:ok, %HTTPoison.Response{status_code: other_status_code}} -> 
      # api was not able to process our request, check body for details
      "some error returned from endpoint"
  {:error, reason} -> 
      "problem with network or reaching/getting endpoint"
end

.

Poison.decode!(body)部分将是这样的
