GAE python:获取和发布请求工作,而无需通过表单提交发布请求

This is a continuation of this question

这是这个问题的延续

What follows is an abbreviated version of the original code. I tried to include the most relevant parts and left out the part of the script used by a cron job which updates the Datastore with values.

以下是原始代码的缩写版本。我尝试包含最相关的部分,并省略了cron作业使用的脚本部分,该部分使用值更新数据存储区。

Then, in the sendFollowUp() handler, a second cron job queries the Datastore for these values, then uses a push task queue to send these values as parameters which are ultimately used in a REST API call to another service that sends people(entities) in the Datastore an email.

然后,在sendFollowUp()处理程序中,第二个cron作业向数据存储区查询这些值,然后使用推送任务队列将这些值作为参数发送,这些参数最终用于对发送人员(实体)的另一个服务的REST API调用中在数据存储区中发送电子邮件。

What I can't figure out is how to follow-up a get request with a post request in the same handler without submitting a post request through a form. This needs to happen within the sendFollowUp handler. Most of the examples I have found include submitting a form. However, I don't want to do that. I just want it to work automatically with the cron job and task queue.

我无法弄清楚的是如何在同一个处理程序中使用post请求跟进get请求而不通过表单提交post请求。这需要在sendFollowUp处理程序中发生。我发现的大多数例子都包括提交表格。但是,我不想这样做。我只是想让它自动与cron作业和任务队列一起工作。

I'm not sure I really understand your question, but can't you just create a POST request with the requests module?

我不确定我是否真的理解你的问题,但是你不能只用请求模块创建一个POST请求吗?

Post Requests

>>> payload = {'key1': 'value1', 'key2': 'value2'}
>>> r = requests.post("http://httpbin.org/post", data=payload)

Also for easy task use have you seen the deferred library?

另外,为了便于任务使用,您是否看过延迟库?

The deferred library lets you bypass all the work of setting up dedicated task handlers and serializing and deserializing your parameters by exposing a simple function, deferred.defer(). To call a function later, simply pass the function and its arguments to deferred.defer

延迟库允许您通过公开一个简单的函数deferred.defer()来绕过设置专用任务处理程序以及序列化和反序列化参数的所有工作。要稍后调用函数,只需将函数及其参数传递给deferred.defer即可
