How to send and receive HTTP POST requests in Python
提问by Idan S
I need a simple Client-side method that can send a boolean value in a HTTP POST request, and a Server-side function that listens out for, and can save the POST content as a var.
我需要一个简单的客户端方法，它可以在 HTTP POST 请求中发送一个布尔值，以及一个可以侦听并将 POST 内容保存为 var 的服务器端函数。
I am having trouble finding information on how to use the httplib.

Please show me a simple example, using localhost for the http connection.

For the client side, you can do all sorts of requests using this python library: requests. It is quite intuitive and easy to use/install.
对于客户端，您可以使用这个 python 库执行各种请求：requests。它非常直观且易于使用/安装。
For the server side, I'll recommend you to use a small web framework like Flask, Bottleor Tornado. These ones are quite easy to use, and lightweight.
对于服务器端，我建议你使用一个小的 web 框架，比如Flask、Bottle或Tornado。这些都很容易使用，而且很轻。
For example, a small client-side code to send the post variable foousing requests would look like this:
例如，foo使用请求发送 post 变量的小型客户端代码如下所示：
import requests
r = requests.post("http://yoururl/post", data={'foo': 'bar'})
# And done.
print(r.text) # displays the result body.
And a server-side code to receive and use the POST request using flask would look like this:
使用flask接收和使用POST请求的服务器端代码如下所示：
from flask import Flask, request
app = Flask(__name__)
@app.route('/', methods=['POST'])
def result():
print(request.form['foo']) # should display 'bar'
return 'Received !' # response to your request.
This is the simplest & quickest way to send/receive a POST request using python.
这是使用 python 发送/接收 POST 请求的最简单、最快捷的方法。
