在python中读取SSE数据 [英] Reading SSE data in python

问题描述

我有一个 SSE 服务器(例如:http://www.howopensource.com/2014/12/introduction-to-server-sent-events/) 发送输出如下.每个数据部分用两个新行分隔 (\n\n).我想写一个简单的python程序来连续显示SSE输出.

I have a SSE server(eg: http://www.howopensource.com/2014/12/introduction-to-server-sent-events/) that sends output as given below. Each data section is separated with two new lines(\n\n). I want to write down a simple python program to display the SSE output continuously.

...

id: 5
data: Got ID: 5 and the data will be like this.

id: 6
data: Got ID: 6 and the data will be like this.

id: 7
data: Got ID: 7 and the data will be like this.

...

我尝试遵循 python 代码.

I tried following python code.

from __future__ import print_function
import httplib

conn = httplib.HTTPConnection("localhost")
conn.request("GET", "/sse.php")
response = conn.getresponse()

while True:
    data = response.read(1)
    print(data, end='')

上面的代码对我来说很完美.但它对每个字符进行迭代.我想知道有什么方法可以在每次迭代中打印每个数据部分.

The above code works perfectly to me. But it do iteration for each character. I wonder there is any way to print each data-section per iteration.

推荐答案

可以使用response.fp.readline逐行读取数据

you can use response.fp.readline to read data line by line

from __future__ import print_function
import httplib
conn = httplib.HTTPConnection("localhost")
conn.request("GET", "/sse.php")
response = conn.getresponse()

while True:
    data = response.fp.readline()
    print(data)
