如何使用hackney在elixir中发送body参数

defp deps do
  [
    {:hackney, "~> 1.17"}
  ]
end

client = Hackney.start

url = "https://example.com/api/endpoint"
method = :post
headers = [
  {"Content-Type", "application/json"}
]
body = Jason.encode(%{key: "value"})
options = [
  {:url, url},
  {:method, method},
  {:headers, headers},
  {:body, body}
]

{:ok, response} = Hackney.request(client, options, [])

defmodule MyModule do
  def send_request do
    client = Hackney.start

    url = "https://example.com/api/endpoint"
    method = :post
    headers = [
      {"Content-Type", "application/json"}
    ]
    body = Jason.encode(%{key: "value"})
    options = [
      {:url, url},
      {:method, method},
      {:headers, headers},
      {:body, body}
    ]

    {:ok, response} = Hackney.request(client, options, [])
    IO.inspect(response)
  end
end

MyModule.send_request
