在使用HTTPie将新用户发布到Rails API时遇到问题

Question

我正在尝试使用 HTTPie 测试我的 Rails 5 API 端点。我在终端中运行的命令是：

http POST :3000/users email=[e-mail] password=anewpassword password_confirmation=anewpassword

我得到的回应是：

HTTP/1.1 400 Bad Request
Cache-Control: no-cache
Content-Type: application/json; charset=utf-8
Transfer-Encoding: chunked
X-Content-Type-Options: nosniff
X-Frame-Options: SAMEORIGIN
X-Request-Id: c3ca4d50-9501-46e9-a7e1-a4576d6cdd7e
X-Runtime: 0.010404
X-XSS-Protection: 1; mode=block
{
  "errors": [
    "Password can't be blank"
  ]
}

这意味着它遇到了我的验证。但是，据我所知，它不应该是。这是我从 Rails 服务器终端得到的：

Started POST "/users" for 127.0.0.1 at 2017-02-03 12:09:54 -0800
Processing by UsersController#create as JSON
  Parameters: {"email"=>"[e-mail]", "password"=>"[FILTERED]",
"password_confirmation"=>"[FILTERED]", "user"=>{"email"=>"[e-mail]"}}
(0.1ms)  BEGIN User Exists (0.4ms)  SELECT  1 AS one FROM "users" 
WHERE LOWER("users"."email") = LOWER($1) LIMIT $2  [["email","[e-mail]"], ["LIMIT", 1]]
(0.1ms)  ROLLBACK
Completed 400 Bad Request in 3ms (Views: 0.1ms | ActiveRecord: 0.6ms)

关于我做错了什么的任何想法？我有一种感觉，我没有正确使用HTTPie，但我找不到太多关于我的Google-fu的东西。

编辑

我可以确认路线正在工作。使用 Postman 并在请求正文中传递以下 JSON 将获得预期的响应：

{"user": {"email": "[e-mail]","password": "anewpassword","password_confirmation": "anewpassword"}}
Response: 
    {"status": "User created successfully"}

在这篇文章的帮助下(使用 HTTPie 发送嵌套的 JSON 对象(，我将我的 HTTPie 请求修改为如下所示：

http POST :3000/users user:='{"email": "[e-mail]", "password": "anewpassword", "password_confirmation": "anewpassword"}'

这给了我预期的回应：
