對於基於REST的Web服務,我很新。我想打電話給小REST WS,我創建了看起來開始如下使用POST調用返回REST Web服務返回415
package webServices;
import java.net.UnknownHostException;
import javax.ws.rs.Consumes;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.json.JSONException;
import org.json.JSONObject;
import com.mongodb.BasicDBObject;
import com.mongodb.DB;
import com.mongodb.DBCollection;
import com.mongodb.DBCursor;
import com.mongodb.MongoClient;
@Path("/login")
public class LoginService {
@Path("/isUp")
@GET
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public String checkServiceStatus(){
return "up and running";
}
@Path("/authenticate")
@POST
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON, MediaType.TEXT_PLAIN })
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public String authenticateUser(@FormParam("user") String user, @FormParam("password") String pwd){
DB db;
DBCollection coll;
MongoClient mongoClient;
String loginResponse="user does not exist";
try {
mongoClient = new MongoClient("localhost" , 27017);
db = mongoClient.getDB("Hackathon");
coll = db.getCollection("users");
BasicDBObject filter = new BasicDBObject();
filter.put("user", user);
BasicDBObject selectField = new BasicDBObject();
selectField.put("password", 1);
selectField.put("_id", 0);
DBCursor cursor = coll.find(filter, selectField);
String jsonString = cursor.next().toString();
JSONObject json = new JSONObject(jsonString);
String password = json.getString(user);
System.out.println("password "+password);
if(password.equals(pwd)){
loginResponse="success";
System.out.println("success");
}else{
loginResponse="failure";
System.out.println("failure");
}
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return loginResponse;
}
}
每當我使用表單數據
http://localhost:8080/HackDataEngine/login/authenticate
Content-Type application/json
user admin
password admin
撥打郵政從Chrome中郵遞員一樣
我得到如下回應

感謝您的快速反應。我嘗試了你的建議,但仍然看到相同的錯誤。我嘗試通過在調試中運行服務器。該控件沒有進入'authenticateUser'方法。所以我懷疑這個問題與** @ Consumes **和** @ FormParam **更相關。感謝您的REST啓動鏈接 – BondCode
歡迎:) – ElMariachi25
