Question

我想使用aiohttp多帖子。而且，我需要发布FILE。但是，我的代码无法正常工作这是我的代码

import aiohttp

file = open('file/path', 'rb')
async with aiohttp.request('post', url, files=file) as response:
   return await response.text()

和request.FILES is None

这是引用通告

    def post(self, url: StrOrURL,
             *, data: Any=None, **kwargs: Any) -> '_RequestContextManager':
        """Perform HTTP POST request."""
        return _RequestContextManager(
            self._request(hdrs.METH_POST, url,
                          data=data,
>                         **kwargs))
E       TypeError: _request() got an unexpected keyword argument 'files'

请....这个可能...？我需要解决方案...请... T ^ T

这是期望的输出

request.FILES['key'] == file

密钥为html格式

<form method="post" name="file_form" id="file_form" enctype="multipart/form-data">
    {% csrf_token %}
    <input type="file" name="key" id="file" />
    <input type="submit" />
</form>

谢谢！它运作良好！但是我还有更多问题我正在使用from django.core.files.uploadedfile import InMemoryUploadedFile 这是我使用py.test

的测试代码

def get_uploaded_file(file_path):
    f = open(file_path, "rb")
    file = DjangoFile(f)
    uploaded_file = InMemoryUploadedFile(file, None, file_path, "text/plain", file.size, None, None)
    return uploaded_file

file = get_uploaded_file(path)
async with aiohttp.request('post', url, data={'key': f}) as response:
        return await response.text()

如何在测试中编写此代码...？

Answer 1

根据POST a Multipart-Encoded File - Client Quickstart - aiohttp documentation，您需要将文件指定为data字典（值应为类似文件的对象）：

import asyncio
import aiohttp


async def main():
    url = 'http://httpbin.org/anything'
    with open('t.py', 'rb') as f:
        async with aiohttp.ClientSession() as session:
            async with session.post(url, data={'key': f}) as response:
                return await response.text()


text = asyncio.run(main())  # Assuming you're using python 3.7+
print(text)

注意：字典关键字应为key，以匹配key中的<input type="file" name="key" id="file" />

客户端：

import requests

url = 'http://SERVER_ADDRESS:PORT/sendfile'
files = {'file': open('data.txt', 'r').read()}
requests.post(url, data=files)

服务器：

from aiohttp import web

PORT = 8082

async def send_file(request):

    data = await request.post()
    with open('data.txt', 'w') as f:
        f.write(data['file'])
    return web.Response(text='ok',content_type="text/html")

app = web.Application(client_max_size=1024**3)
app.router.add_post('/sendfile', send_file)

web.run_app(app,port=PORT)

Answer 3

对于接收二进制数据，您可以使用 read 请求函数。

例如接收一个文本文件将如下所示：

from aiohttp import web

async def receive_post_request(request)
    data = (await request.read()).decode('utf-8')
    return web.Response(text='data', content_type="text/html")

如何aiohttp请求发布文件列表python请求模块？
