当我在url上传递参数时,我曾经尝试过@QueryParam 还有@PathParam之后,我只是尝试通过http协议进行调用。它不起作用。
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Path("/putOtdDebt")
public Response putOtdDebt(@HeaderParam("username") String username,
@HeaderParam("password") String password) {
System.out.println("username: " + username);
System.out.println("password: " + password);
return Response.status(201).entity("{\"testStr\": \"Call putOtdDebt\"}").build();
}
我试图这样打电话:
Client client = Client.create();
WebResource webResource = client
.resource("http://localhost:8080/BgsRestService/rest/bgs/putOtdDebt");
String input = "{\"username\":\"testuser\",\"password\":\"testpassword\"}";
ClientResponse response = webResource.type("application/json")
.post(ClientResponse.class, input);
if (response.getStatus() != 201) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatus());
}
System.out.println("Output from Server .... \n");
String output = response.getEntity(String.class);
System.out.println(output);
结果是参数为空:
username: null
password: null
help me! how can i get post parameters?
答案 0 :(得分:1)
您正在通过input
通话将POST
字符串作为正文传递
String input = "{\"username\":\"testuser\",\"password\":\"testpassword\"}";
在服务器端代码中,您使用@HeaderParam
从不正确的正文中获取值,@HeaderParam
用于获取标头值
公共@interface HeaderParam
将HTTP标头的值绑定到资源方法参数,资源类字段或资源类bean属性。
您可以接受POST
主体作为字符串,如果要获取username
和password
,则需要将字符串解析为JsonObject
并获取值
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Path("/putOtdDebt")
public Response putOtdDebt(String body) {
System.out.println("body: " + body);
}
或者您也可以使用这两个属性创建POJO并直接将其映射
public class Pojo {
private String username;
private String password;
//getters and setters
}
服务器代码
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Path("/putOtdDebt")
public Response putOtdDebt(Pojo body) {
System.out.println("username: " + body.getUsername());
System.out.println("password: " + body.getPassword());
}
