关于rest：泽西岛客户端不遵循重定向

Jersey client doesn't follow redirects

我的"用户"资源定义如下：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

@Path("/api/users")
public class UserResource {

@POST
@Consumes(MediaType.APPLICATION_JSON)
public Response addUser(User userInfo) throws Exception {
String userId;
User existing = ... // Look for existing user by mail
if (existing != null) {
userId = existing.id;
} else {
userId = ... // create user
}
// Redirect to the user page:
URI uri = URI.create("/api/users/" + userId);
ResponseBuilder builder = existing == null ? Response.created(uri) : Response.seeOther(uri);
return builder.build();
}

@Path("{id}")
@GET
@Produces(MediaType.APPLICATION_JSON)
public User getUserById(@PathParam("id") String id) {
return ... // Find and return the user object
}
}

然后，我正在尝试使用 Jersey 客户端测试用户创建：

1
2
3
4
5
6
7
8
9
10
11
12
13

ClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
clientConfig.getFeatures().put(ClientConfig.PROPERTY_FOLLOW_REDIRECTS, Boolean.TRUE);
Client client = Client.create(clientConfig);
client.addFilter(new LoggingFilter(System.out));

User userInfo = UserInfo();
userInfo.email ="test";
userInfo.password ="test";
client.resource("http://localhost:8080/api/users")
.accept(MediaType.APPLICATION_JSON)
.type(MediaType.APPLICATION_JSON)
.post(User.class, userInfo);

我得到以下异常：

SEVERE: A message body reader for Java class com.colabo.model.User,
and Java type class com.colabo.model.User, and MIME media type
text/html; charset=iso-8859-1 was not found

这是 HTTP 请求的踪迹：

1
2
3
4
5
6
7
8
9
10
11
12

1 * Client out-bound request
1 > POST http://localhost:8080/api/users
1 > Accept: application/json
1 > Content-Type: application/json
{"id":null,"email":"test","password":"test"}
1 * Client in-bound response
1 < 201
1 < Date: Tue, 03 Jul 2012 06:12:38 GMT
1 < Content-Length: 0
1 < Location: /api/users/4ff28d5666d75365de4515af
1 < Content-Type: text/html; charset=iso-8859-1
1 <

在这种情况下，Jersey 客户端是否应该自动遵循重定向，并从第二个请求中正确解组并返回 Json 对象？

谢谢，
迈克尔

我遇到了同样的问题，并通过以下客户端过滤器解决了它

package YourPackageName;

import javax.ws.rs.client.ClientRequestContext;
import javax.ws.rs.client.ClientResponseContext;
import javax.ws.rs.client.ClientResponseFilter;
import javax.ws.rs.core.Response;
import java.io.IOException;
import java.io.InputStream;

public class RedirectFilterWorkAround implements ClientResponseFilter {
@Override
public void filter(ClientRequestContext requestContext, ClientResponseContext responseContext) throws IOException {
if (responseContext.getStatusInfo().getFamily() != Response.Status.Family.REDIRECTION)
return;

Response resp = requestContext.getClient().target(responseContext.getLocation()).request().method(requestContext.getMethod());

responseContext.setEntityStream((InputStream) resp.getEntity());
responseContext.setStatusInfo(resp.getStatusInfo());
responseContext.setStatus(resp.getStatus());
}
}

现在在您创建客户端的其他类中

1	Client client = ClientBuilder.newClient();

将此过滤器类应用为

1	client.register(RedirectFilterWorkAround.class);

这适用于 Jersey 2.x
