我一直在尝试使用Google Cloud Endpoints为我的应用设置后端,在我实际尝试将实体插入数据存储区之前,一切似乎都进展顺利。
我尝试使用生成的端点将GenericBike对象插入数据存储区,当代码编译并且似乎成功运行时,在检查项目网页时实际上并未插入任何内容。
这是我实际插入的代码。
private class AddGenericBikeAsyncTask extends AsyncTask<GenericBike, Void, Void> {
@Override
protected Void doInBackground(GenericBike... params) {
GenericBikeApi.Builder builder = new GenericBikeApi.Builder(AndroidHttp.newCompatibleTransport(),
new AndroidJsonFactory(), null)
.setRootUrl("https://banded-coder-125919.appspot.com/_ah/api/");
GenericBikeApi service = builder.build();
try {
GenericBike bike = params[0];
Log.e("Debug", "Inserting bike...");
service.insert(bike);
Log.e("Debug", "Done inserting bike.");
} catch (IOException e) {e.printStackTrace(); }
return null;
}
}
这就是我称之为的地方
if (mGenericBikes == null) { // we need to preload the database still
for (int i=0; i<10; i++) {
GenericBike bike = new GenericBike();
bike.setId(new Long(i+1));
new AddGenericBikeAsyncTask().execute(bike);
}
}
如果有帮助,这是我的GenericBike权利。
@Entity
public class GenericBike {
@Id Long mId;
boolean mAtStation;
public GenericBike() {
mAtStation = true;
}
public Long getId() {
return mId;
}
public void setId(Long id) {
mId = id;
}
public boolean isAtStation() {
return mAtStation;
}
public void setAtStation(boolean atStation) {
mAtStation = atStation;
}
编辑:这是insert()方法生成的端点代码
/**
* Inserts a new {@code GenericBike}.
*/
@ApiMethod(
name = "insert",
path = "genericBike",
httpMethod = ApiMethod.HttpMethod.POST)
public GenericBike insert(GenericBike genericBike) {
// Typically in a RESTful API a POST does not have a known ID (assuming the ID is used in the resource path).
// You should validate that genericBike.mId has not been set. If the ID type is not supported by the
// Objectify ID generator, e.g. long or String, then you should generate the unique ID yourself prior to saving.
//
// If your client provides the ID then you should probably use PUT instead.
ofy().save().entity(genericBike).now();
logger.info("Created GenericBike.");
return ofy().load().entity(genericBike).now();
}
答案 0 :(得分:1)
您似乎没有从客户端发送请求。我相信您需要将.execute()添加到您的client-lib对象以实际启动请求。
替换
service.insert(bike);
与
service.insert(bike).execute();
此外,检查您的App Engine日志是确认请求实际通过的良好起点。
