Question

当我尝试使用cURL在我的localhost上发布请求时出现以下错误。

我发送的请求：

C:\Program Files (x86)\cURL\bin>curl -v -H "Content-type: application/json" -H "Accept: application/json" -X POST http://localhost:3000/users/sign_in -d '{"user": {"email":"email2@email.com", "password":"1234"}}'

这是我得到的错误：

    *   Trying ::1...
* Connected to localhost (::1) port 3000 (#0)
> POST /users/sign_in HTTP/1.1
> Host: localhost:3000
> User-Agent: curl/7.46.0
> Content-type: application/json
> Accept: application/json

问题是我的GET请求工作得很好，但POST请求无效。

我尝试使用转义引号：

C:\Program Files (x86)\cURL\bin>curl -v -H "Content-type: application/json" -H "Accept: application/json" -X POST http://localhost:3000/users/sign_in -d "{\"user\": \"{\"email\":\"email2@email.com\", \"password\":\"1234\"}\"}"

错误开始：

    Note: Unnecessary use of -X or --request, POST is already inferred.
*   Trying ::1...
* Connected to localhost (::1) port 3000 (#0)

我几天来一直试图解决同样的问题而且我非常讨厌Windows。有什么建议吗？

正如对this问题中的答案的评论中所建议的那样，请尝试避免使用单引号，而是转义其他代码：-d "{\"user\": \"....\"}"
