如何通过httpx传递带有名称的文件的表单

Question

我试图通过httpx将数据发送到戈滕贝格容器。

r = httpx.post(
     "http://doc-to-pdf:3000/forms/chromium/convert/html",
     files={
         "index.html": file_bytes,
     },
     params={
         "marginTop": 0.4,
         "marginBottom": 0.45,  # 0.39 minimum for appending page number
         "marginLeft": 0.1,
         "marginRight": 0.1,
     },
)

但我错了

('Error from gotenberg, %r , %r', 400, b"Invalid form data: form file 'index.html' is required")

知道为什么没有通过httpx传递文件名吗？

Answer 1

https://www.python-httpx.org/quickstart/搜索“发送多部分文件上载”

>>> files = {'{file}': open('report.xls', 'rb')}
>>> r = httpx.post("{url}", files=files)
>>> print(r.text)
{
  ...
  "files": {
    "{file}": "<... binary content ...>"
  },
  ...
}


Where {file} is the name of field in your {url}-endpoint schema
i.e: 
@router.post({url})
def test_file(
    {file}: UploadFile
):
    pass
