前言

某个美丽的下午,运维把服务器上的nginx升级了,http协议也变成了http2.0,我本地的requests再也连接不到服务器,然后就找到了额hyper

但是hyper的文档写的很简单,而且相比requests来说还没那么人性化,看着demo说吧

hyper简单使用

from hyper import HTTP20Connection

conn = HTTP20Connection(host='xxx.xxx.xxx.xxx', port=80)
# host直接写域名或者IP地址,不要加http或https
# port默认是443
response = conn.request(method='POST', url='/post', body=None, headers=None) # 你会发现这里没有data参数
resp = conn.get_response(response)
print(resp.read()) # 二进制,相当于requests中返回的res.content

你会发现,没有data参数,其实我们也能想到就算写了data,最后我们进行传输的时候data也会被放到body里面,但是具体怎么转化的,我参考了requests模块

requests模块中对data做了怎样的转换

from collections.abc import Mapping
from urllib.parse import urlencode def to_key_val_list(value):
if value is None:
return None if isinstance(value, (str, bytes, bool, int)):
raise ValueError('cannot encode objects that are not 2-tuples') if isinstance(value, Mapping):
value = value.items() return list(value) def _encode_params(data):
if isinstance(data, (str, bytes)):
return data
elif hasattr(data, 'read'):
return data
elif hasattr(data, '__iter__'):
result = []
for k, vs in to_key_val_list(data):
if isinstance(vs, (str, bytes)) or not hasattr(vs, '__iter__'):
vs = [vs]
for v in vs:
if v is not None:
result.append(
(k.encode('utf-8') if isinstance(k, str) else k,
v.encode('utf-8') if isinstance(v, str) else v))
return urlencode(result, doseq=True)
else:
return data data = {"name": "tom", "ege": "20"}
print(_encode_params(data)) # name=tom&ege=20

上面这段代码是我从requests源码中截取出来的,可以直接运行,结果为name=tom&ege=20,看到这个我们就明白如何转换的了,接下来我们就可以用hyper发送表单数据了

hyper发送表单数据

from hyper import HTTP20Connection

conn = HTTP20Connection(host='xxx.xxx.xxx.xxx', port=80)
response = conn.request(method='POST', url='/post',
body='name=tom&age=20',
headers={'Content-Type': 'application/x-www-form-urlencoded'})
resp = conn.get_response(response)

一定要记得加请求头,这样可以和之前使用requests的接口进行对接了
