我正在尝试使用Windows 10上的cURL向我的localhost发送POST请求。我正在使用Ruby on Rails,我的数据库是PostgresQL。我尝试了所有在各处发布的解决方案,但没有一个正在发挥作用。
这就是cURL中的一个类型:
curl -v -g -H "Accept: application/json" -H "Content-type: application/json" -H "Authorization: NVNNymcrAExBdDsaje9z" -X POST http://localhost:3000/users/reservations -d '{"reservation": {"venue":"new Venue", "venue_id":"1", "reservation_date":"2016/04/26", "num_people":"3", "num_bottles":"1"}}'
这是我得到的错误:
Note: Unnecessary use of -X or --request, POST is already inferred.

* Could not resolve host: num_bottles

我尝试使用这样的转义引号:
curl -v -g -H "Accept: application/json" -H "Content-type: application/json" -H "Authorization: NVNNymcrAExBdDsaje9z" -X POST http://localhost:3000/users/reservations/ -d {\"reservation\": {\"venue\":\"new Venue\", \"venue_id\":\"1\", \"reservation_date\":\"2016/04/26\", \"num_people\":\"3\", \"num_bottles\":\"1\"}}
这是我使用转义引号得到的错误:

我也尝试在curl / bin中移动我的数据文件并使用-d @ text.txt,如下所示:
curl -v -g -H "Accept: application/json" -H "Content-type: application/json" -H "Authorization: NVNNymcrAExBdDsaje9z" -X POST http://localhost:3000/users/reservations -d @text.txt
这是错误:
Note: Unnecessary use of -X or --request, POST is already inferred.
* Trying ::1...
* Trying 127.0.0.1...
* connect to ::1 port 3000 failed: Connection refused
* connect to 127.0.0.1 port 3000 failed: Connection refused
* Failed to connect to localhost port 3000: Connection refused

我愿意接受任何建议吗?您认为我的问题是什么?如何解决此问题并发出正确的POST请求?
