HTTP/1.1 401上的捲曲請求未經授權錯誤 - Heroku的

Question

我試圖通過捲曲發送請求到我的Heroku基於API，但我不斷收到此錯誤：

* 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) 
> POST /users/sign_in HTTP/1.1

這是我的捲髮要求：

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"}}' 

UPDATE

這是日誌：

2015-01-16T21:43:04.342815+00:00 app[web.1]: Processing by SessionsController#create as */* 
2015-01-16T21:43:04.342822+00:00 app[web.1]: Parameters: {"{\"user\": {\"email\": \"xxxxxx@gmail.com\", \"password\": \"xxxxxxx\"}}"=>nil}

updating...done. Updated to 3.23.2 

電子郵件和密碼是正確和chequed，順便說一句。

Answer 1

你-d參數應的X WWW的形式，進行了urlencoded像查詢字符串：

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

如果你想繼續使用JSON你是你必須將Content-type頭添加的方式你-H：

Content-type: application/json 

這讓我們的服務器知道解釋你的POST數據作爲JSON，而不是X WWW的形式，進行了urlencoded字符串。這就是爲什麼在服務器日誌中的參數出來，如：

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

這只是一個字符串，而不是JSON，因爲服務器不知道你在發送JSON，因爲你沒有包含內容 - 類型標題和默認服務器假定POST數據是一個x-www-form-urlencoded字符串。
