我是一个试图通过python 2.7执行aws cloudformation脚本的python新手。该脚本可以从aws控制台和命令行完美运行。但是，当我尝试在python中运行时，我收到错误“模板格式错误：JSON格式不正确。（第1行，第5列）”
def create_stack(args):
conn = _create_cf_connection(args)
try:
conn.create_stack(args.stack_name, template_body="file://D://Project/testTemplate.json")
except boto.exception.BotoServerError, e:
print e.error_message
我运行'validate-template'并且没有返回任何错误。任何人都可以帮助我吗？
这是json模板：

template_body需要一个字符串。请尝试使用template_url或使用其他代码将本地磁盘上的文件加载到字符串
