将 cURL 转换为 Python - 上传文件

Question

我似乎无法将 cURL 转换为 python。来自文档：

curl -i --upload-file ~/Desktop/Myimage.jpg -H 'Authorization: Bearer Redacted' "https://api.linkedin.com/mediaUpload/C5522AQHn46pwH96hxQ/feedshare-uploadedImage/0?ca=vector_feedshare&cn=uploads&m=AQLKRJOn_yNw6wAAAW2T0DWnRStny4dzsNVJjlF3aN4-H3ZR9Div77kKoQ&app=1983914&sync=0&v=beta&ut=1Dnjy796bpjEY1

我尝试使用文件而不是数据无济于事。

下面的当前代码创建了正确的响应 201，但它是空白的（没有 JSON 详细信息以及用于未来 API 调用的图像）。让我在不使用多部分表单（即“files=”）的情况下通过 PUT 请求上传文件需要进行哪些更改

uploadUrl = data["value"]["uploadMechanism"]["com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest"]["uploadUrl"]

filename = "ffadfads.jpeg"
media_url = "https://1000logos.net/wp-content/uploads/2017/03/LinkedIn-Logo.png"
request = requests.get(media_url, stream=True)
if request.status_code == 200:
    with open(filename, 'wb') as image:
        for chunk in request:
            image.write(chunk)
    #files = {'fileupload': open(filename)}
    files = {"fileupload":(filename,open(filename,"rb"),'application-type')}
    image_headers = {
        'Accept': 'image/jpeg,image/png,image/gif',
        'Authorization': 'Bearer ' + real_token
    }
    response = requests.request("PUT", uploadUrl, data=open(filename,"rb"), headers=image_headers)
    print response
    print response.text
    print response.json()

Answer 1

尽量不要混淆请求和响应。

response1 = requests.get(media_url, stream=True)
if response1.status_code == 200:
    response2 = requests.request("PUT", uploadUrl,
                                 data=response1.iter_content(),
                                 headers=image_headers)

Answer 2

如果您未绑定使用 requests 库，您可以尝试直接从 python 运行 curl 命令，对于 Python 3 使用 subprocess.run() 和 shlex.split()。

使用您问题中的示例 curl 命令（在末尾添加缺少的双引号），以下代码将运行它并将响应捕获为文本。

import shlex
import subprocess

curl_command_line = '''curl -i --upload-file ~/Desktop/Myimage.jpg \
-H 'Authorization: Bearer Redacted' \
"https://api.linkedin.com/mediaUpload/C5522AQHn46pwH96hxQ/feedshare-uploadedImage/0?ca=vector_feedshare&cn=uploads&m=AQLKRJOn_yNw6wAAAW2T0DWnRStny4dzsNVJjlF3aN4-H3ZR9Div77kKoQ&app=1983914&sync=0&v=beta&ut=1Dnjy796bpjEY1"'''

args = shlex.split(curl_command_line)
response = subprocess.run(args, capture_output=True, text=True).stdout

对于 Python 2.7，将最后一行替换为：

response = subprocess.call(args)
