API 请求不与 rest-client 一起使用，但与 Faraday/cURL 一起使用

Question

我有一个 GET 请求来查询 JOOR API 以检索他们的产品类别列表。

此请求适用于 cURL 或 Faraday gem，但不适用于 rest-client gem。测试请求结果如下：

1) 使用 cURL

curl -X GET \
  https://apisandbox.jooraccess.com/v2/categories/ \
  -H 'Authorization: Bearer [mytoken]' \
  -H 'Content-Type: application/json'

2) 与法拉第

conn = Faraday.new(url: 'https://apisandbox.jooraccess.com/v2/categories')
conn.get do |req|
  req.headers['Content-Type'] = 'application/json'
  req.headers['Authorization'] = 'Oauth2 [mytoken]'
end

3) 使用休息客户端

response = ::RestClient::Request.execute(method: :get, url: 'https://apisandbox.jooraccess.com/v2/categories', headers: {'Content-Type': 'application/json', 'Authorization': 'Oauth2 [mytoken]'})

1) 和 2) 都获得了带有类别列表的预期响应，但 3) 收到了带有“不支持请求/响应格式”的投诉的响应

那么 3) 和 1)/2) 有什么区别？为什么只有 3) 失败？

========== 更新==========

使用 httplog gem 记录 Faraday 和 Rest-client 请求的标头信息。这是日志。

法拉第：

休息客户端：

</response>

这表明 header 中的 Content-Type 可能在 rest-client 处理后没有正确传递。所以我使用 rest-client 的方式可能不正确。怎么改？

Answer 1

尝试将其更改为您的休息客户端代码

response = ::RestClient::Request.execute(method: :get, url: 'https://apisandbox.jooraccess.com/v2/categories', headers: {'Content-Type': 'application/json', 'Accept': 'application/json', 'Authorization': 'Oauth2 [mytoken]'})

Answer 2

我必须在休息客户端请求的标题中添加accept: '*/*'。它有效。
