Python 请求模拟 CURL POST 发送带有 1 个或多个文件和 JSON 正文的多部分请求

Question

我已经破解了两天了，没有运气！

工作卷曲请求

curl -X POST -v "http://$1:8080/controller/endpoint" -H "Cache-Control: no-cache" -H "Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW" -F "message={ \"id\": \"b3562c86-6ff4-4bf7-9c4a-4c64fff4d0ea\", \"stuff\": [

{

\"id\": \"1ca2d9b1-1d73-432a-b483-be404afff8da\",

.......

\"endTime\": \"\"

}]}};type=application/json" -F "files=@file.zip"

返回如下所示的输出：

 ./rest.sh http://127.0.0.1/anything

您的脚本应如下所示：注意：有依赖requests_toolbeltsend.pyimport argparseimport requestsfrom requests_toolbelt import MultipartEncoderparser = argparse.ArgumentParser()parser.add_argument('message')parser.add_argument('--files', nargs='+')args = parser.parse_args()multipart_form_data_object = MultipartEncoder(&nbsp; &nbsp; fields=(&nbsp; &nbsp; &nbsp; &nbsp; ('files', (args.files[0], open(args.files[0], 'rb'), "application/json")),&nbsp; &nbsp; &nbsp; &nbsp; ('files', (args.files[1], open(args.files[1], 'rb'), "application/json")),&nbsp; &nbsp; &nbsp; &nbsp; ('message', ('message', open(args.message, 'rb'), 'application/json')),&nbsp; &nbsp; ))res = requests.post('http://localhost:8000', data=multipart_form_data_object, headers={'Content-Type': multipart_form_data_object.content_type})print(res.content)我使用 django 对其进行了测试：urls.pyfrom django.urls import pathfrom django.http import JsonResponsefrom django.views.decorators.csrf import csrf_exempt@csrf_exemptdef dump(request):&nbsp; &nbsp; data = {name: [o.read().decode('utf8') for o in request.FILES.getlist(name)] for name in request.FILES.keys()}&nbsp; &nbsp; return JsonResponse(data)urlpatterns = [&nbsp; &nbsp; path('', dump),]使用以下方法调用它：curl -s http://127.0.0.1:8000/ -F "message=@$(pwd)/file1" -F "files=@$(pwd)/file2" -F "files=@$(pwd)/file3"并使用pythonpython send.py file1 --files file2 file3相同的输出：{"files": ["{\\"message\\": \\"hello world\\"}\\n", "something else\\n"], "message": ["hello world\\n"]}
