Python 通过GAE头发布请求

我从GAE Flask服务向其他GAE Flask服务发送POST请求

try:
    service_url = 'http://localhost:4040/getservice'
    headers = {
        'Content-Type': 'application/json',
        'Cache-Control': 'no-cache',
        'Auth-Key': AUTH_KEY,
        'Customer': str(CUSTOMER)
    }

    s = Session()
    req = requests.Request('POST', service_url, data=conf, headers=headers)
    readytogo = req.prepare()

    #del readytogo.headers['Content-Lenght']
    #del readytogo.headers['Host']

    module = s.send(readytogo)

except Exception as e:
    print('error')
    print(e)
    return e

但我有一个错误：

Stripped prohibited headers from URLFetch request: ['Host', 'Content-Length']

如果我删除了该标题我在控制台中有此错误：

error
'content-lenght'

第页中出现此错误：

An internal error occurred:
'exceptions.KeyError' object is not callable
See logs for full stacktrace.

GAE不支持标题内容长度和主机！

如何将POST请求从GAE发送到其他GAE端点？？？

您在删除标题的语句中有一个输入错误，这就是导致错误的原因：

del readytogo.headers['Content-Lenght']

而不是

del readytogo.headers['Content-Length']
