HTTP Status 415 - Cannot consume content type

javajsonresteasypostman

提问by AvenashKrish

POST operation to the REST service with JSON body returning

对 REST 服务的 POST 操作返回 JSON 正文

org.jboss.resteasy.spi.UnsupportedMediaTypeException

: Cannot consume content type exception

org.jboss.resteasy.spi.UnsupportedMediaTypeException

: 不能使用内容类型异常

Both @Consumes(MediaType.APPLICATION_JSON)and @Consumes("application/json")returned same exception.

双方@Consumes(MediaType.APPLICATION_JSON)@Consumes("application/json")返回相同的异常。

I tried calling the service using Postman API client.

我尝试使用 Postman API 客户端调用该服务。

                usr.getPassword().compareTo("pass") == 0){                      
        return Response.status(200).build(); 
    }
    else{
        return Response.status(401).build();
    }

You have not set the Content-Typeheader. Don't remember what the default is, but you can look in the Chrome developer tools to see the full request with headers.

您尚未设置Content-Type标题。不记得默认值是什么,但您可以查看 Chrome 开发人员工具以查看带有标头的完整请求。

The JSONvalue in the drop-down is only for syntax highlighting. It doesn't actually set the header. So just add the header

JSON在下拉值仅适用于语法高亮。它实际上并没有设置标题。所以只需添加标题

Content-Type   ->>   application/json
