Question

我是GAE和PiCould的新手，当我想从GAE调用已发布的函数时，我有一些基本的问题。看来我调用已发布函数的方法无法识别。你能给我一些建议吗？

感谢您的帮助！

更新：我不确定为什么人们认为这个问题没有价值。我的观点是，由于GAE只接受纯Python文件，因此有必要为其他语言编写的模型（即Fortran77）找到一种方法。因此，一些非Python程序可以上传到其他云服务器，如PiCloud，然后由GAE调用。在人们的帮助下（谢谢！）我已经找到了这个问题。我已在下面附上我的代码供其他人参考：

该行应为：

output_val = json.loads(response.content)

从Google App Engine调用PiCloud功能时出现问题
