英文:
Google cloud endpoints generate Java api HTTP 400 error
问题
嗨，我正在尝试使用这个文档go-endpoints开发一个REST API。
我可以在本地和应用引擎上测试我的应用程序。
但是我无法创建一个Java客户端来在Android设备上使用它，因为某种原因我得到了一个错误信息：
> HTTP 400 无法解码JSON对象
在这个命令上：
GO_SDK/endpointscfg.py gen_client_lib java MY_FILE_NAME
这是完整的堆栈跟踪：
mik@mik-Aspire-S3:~/go-programs/src/cloudEndPoints/app$ $HOME/go_appengine/endpointscfg.py gen_client_lib java ballota_test

raise ServerRequestException(error)

更新
我尝试构建这个示例项目tictactoe作为一个Java客户端，我得到了相同的错误。
英文:
Hey im trying to develop a rest API by using this doc go-endpoints
I can test my app locally and on the app engine .
But i cant create a Java client in order to consume it on android device,
for some reason I'm getting an
> HTTP 400 No JSON object could be decoded
on this command
GO_SDK/endpointscfg.py gen_client_lib java MY_FILE_NAME
This is the full stack trace

I tried to built this sample project tictactoe as a Java client and i got the same error

我在crhym3的云端点示例中发布了一个问题，他帮助我理解了我的错误。
我的错误是我尝试使用错误的URL地址创建客户端。
这是错误的地址。
https://winged-precept-894.appspot.com 这将返回404错误
而这是正确的发现API URL。
https://winged-precept-894.appspot.com/_ah/api/discovery/v1/apis/myapp/v1/rpc
所以这是一个URL错误，而不是一个JSON导向的错误。
英文:
I posted an issue in
crhym3 cloud endpoints example and he helped my to understand my error.
My mistake was that i tried to create the client with the wrong URL address .
This is the wrong address.
https://winged-precept-894.appspot.com this will return 404
And this is the correct discovery api URL.
https://winged-precept-894.appspot.com/_ah/api/discovery/v1/apis/myapp/v1/rpc
So it was a url error and not a Json oriented error .
