HTTP/1.1 curl 请求时出现 401 未经授权的错误 - heroku

Question

我正在尝试通过 curl 向基于我的 heroku 的 api 发送请求，但我一直收到此错误：

* Hostname was NOT found in DNS cache
*   Trying 23.21.169.234...
* Connected to helphy-api.herokuapp.com (23.21.169.234) port 80 (#0)

这是我的 curl 请求：

curl -v -H "Authorization: Bearer $TUTORIAL_KEY, Accept: application/json" -X POST http://helphy-api.herokuapp.com/users/sign_in   -d '{"user": {"email": "xxxxxxx@gmail.com", "password": "xxxxxxx"}}'

更新

这是日志：

2015-01-16T21:43:04.342822+00:00 app[web.1]:   Parameters: {"{\"user\": {\"email\": \"xxxxxx@gmail.com\", \"password\": \"xxxxxxx\"}}"=>nil}

电子邮件和密码正确并已检查，顺便说一句。

你的 -d 参数应该是 x-www-form-urlencoded 就像一个查询字符串：

user[email]=email&user[password]=password

如果您想继续像现在这样使用 JSON，您必须将 Content-type header 添加到您的 -H:

Content-type: application/json

这让服务器知道将您的 POST 数据解释为 JSON 而不是 x-www-form-urlencoded 字符串。这就是为什么在服务器日志中出现如下参数的原因：

Parameters: {"{\"user\": {\"email\": \"xxxxxx@gmail.com\", \"password\": \"xxxxxxx\"}}"=>nil}

那只是一个字符串，不是 JSON 因为服务器不知道你发送它 JSON 因为你没有包含 Content-type header默认情况下，服务器假定 POST 数据是 x-www-form-urlencoded 字符串。
