httpx AsyncClient -missing方法prepare_request

Question

我试图从这个链接中移植“准备好的请求”示例：https://docs.python-requests.org/en/latest/user/advanced/使用httpx AsnycClient。

from requests import Request, Session

s = Session()
req = Request('GET',  url, data=data, headers=headers)

prepped = s.prepare_request(req)

# do something with prepped.body
prepped.body = 'Seriously, send exactly these bytes.'

# do something with prepped.headers
prepped.headers['Keep-Dead'] = 'parrot'

resp = s.send(prepped,
    stream=stream,
    verify=verify,
    proxies=proxies,
    cert=cert,
    timeout=timeout
)

print(resp.status_code)

但是，我找不到在httpx异步库中准备请求的任何方法。特别是，"prepare_request“方法似乎没有实现。

有人能告诉我如何使用AsyncClient准备请求吗？

任何暗示都是非常感谢的。

Answer 1

可以使用httpx.Request类编写prepare_request工厂。

import httpx


def prepare_request(method, url, **kwargs):
    # a very simple factory
    return httpx.Request(method, url, **kwargs)


request = prepare_request("GET", "https://www.google.com")

client = httpx.Client()

response = client.send(request)

print(response, response.num_bytes_downloaded )

仅用于演示的同步客户端
