我有一个可编译的App-Engine应用程序,我在localhost(https://developers.google.com/apis-explorer/?base=http://localhost:8888/_ah/api#p/)上使用Google Apis Explorer测试方法调用 它工作正常,我可以使用Apis Explorer界面测试我的api方法,但只要我添加一个新的Apimethod
@ApiMethod(name = "users.insertrandomuserv4")
public User insertrandomuserv4() {
User user = new User("234","myfirstname","mysecondname");
return user;
}
我在本地重新部署我的应用程序,Apis Explorer没有显示不同api方法的列表。 为什么? (仅供参考:当我删除新方法时,它会再次起作用)
编辑: 这是我班级的其余部分(是的,我使用PersistentManager和DataStoreService,但它仅用于测试):
public class UserEndpoint {
@ApiMethod(name = "users.get")
public User get(@Named("key") String key) {
//Key k = KeyFactory.createKey(User.class.getSimpleName(), key);
PersistenceManager pm = getPersistenceManager();
User user = pm.getObjectById(User.class, key);
pm.close();
return user;
}
@ApiMethod(name = "users.list")
public List<User> list() {
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Query query = new Query("User");
//query.setKeysOnly();
PreparedQuery pq = datastore.prepare(query);
List<Entity> ls = pq.asList(FetchOptions.Builder.withLimit(500));
List<User> flist = new ArrayList<User>();
for (Entity user : ls) {
User u = new User(user);
flist.add(u);
}
return flist;
}
@ApiMethod(name = "users.insert")
public User insert(User user) {
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Entity ent = user.toEntity();
datastore.put(ent);
return user;
}
@ApiMethod(name = "users.insertrandomuserv4")
public User insertrandomuserv4() {
User user = new User("234","myfirstname","mysecondname");
return user;
}
@ApiMethod(name = "users.getuserswithsamehometown")
public List<User> getUsersWithSameHometown(@Named("home")String home) {
DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Query query = new Query("User");
//query.addProjection(new PropertyProjection("firstname", User.class));
query.setFilter(new Query.FilterPredicate("hometown",FilterOperator.EQUAL,home));
PreparedQuery pq = datastore.prepare(query);
List<Entity> ls = pq.asList(FetchOptions.Builder.withLimit(500));
List<User> flist = new ArrayList<User>();
for (Entity ent : ls) {
User u = new User(ent);
flist.add(u);
}
return flist;
}
private static PersistenceManager getPersistenceManager() {
return JDOHelper.getPersistenceManagerFactory("transactions-optional").getPersistenceManager();
}
}
答案 0 :(得分:5)
是的,这里有路径碰撞。在我对您的代码的审核中,我认为存在两个冲突:users.get
与users.getuserswithsamehometown
冲突,users.insert
与users.insertrandomuserv4
冲突。
您使用的命名约定可以防止API客户端库中的冲突,但不会阻止用于调用API的实际路径。例如,两个.get
调用都映射到GET users/{string}
,而.insert
个调用都映射到POST users
。
您应该做的是为每对中的一个冲突方法添加路径参数。例如,users.getuserswithsamehometown
您可以更新为:
@ApiMethod(
name = "users.getuserswithsamehometown",
path = "users/hometown/{home}",
httpMethod = "GET"
)
这将为该方法提供一个不再与其他users.get
方法冲突的路径。您可以为有冲突的.insert
电话重复此过程,例如:
@ApiMethod(
name = "users.insertrandomuserv4",
path = "users/random/",
httpMethod = "POST"
)
我已经添加了httpMethod声明以获得良好的衡量标准。当你开始修改路径的其他部分时,通常最好声明这些。
