Question

我在弹簧RequestMapping中设置了@Controller，我无法正确发送CURL请求。尝试发送各种方法时，我一直收到HTTP 400返回码。我不确定设置错误。

这是请求

curl -v -X POST localhost:8082/api/registerDevice -d '{"serial":"FA541YJ05065"}' -H "Content-Type:application/json;charset=UTF-8"

这是输出

Note: Unnecessary use of -X or --request, POST is already inferred.

Spring RequestMapping

 @RequestMapping(value = "registerDevice", method = RequestMethod.POST)
  public ResponseEntity<String> registerDevice(@RequestBody Map<String, Object> payload) throws Exception {

更新

如下所述，这是一个转义引号并与Windows相关的问题。相同的CURL命令在centos上运行良好。

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d "{"""serial""":"""FA541YJ05065"""}" http://localhost:8082/api/deregisterDevice

On Centos

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"serial":"FA541YJ05065"}' http://localhost:8082/api/registerDevice

Answer 1

这背后的唯一原因是您的请求格式不正确有关详细信息，请查看此Spring 4.x/3.x (Web MVC) REST API and JSON2 Post requests, how to get it right once for all?。

Answer 2

我怀疑你最终在json的开头发送了'。您可以尝试在json周围使用双引号并在其中转义它们。 See also

curl -v -X POST localhost:8082/api/registerDevice -d "{\"serial\":\"FA541YJ05065\"}" -H "Content-Type:application/json;charset=UTF-8"

卷曲不适用于HTTP Post到Spring-data-rest RequestMapping
