Java Python请求模拟带有1个或多个文件和JSON主体的CURL-POST发送多部分请求

我已经做了两天了，运气不好

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：

你看到区别了吗？这两个文件现在嵌入到表单/文件中，而不是单独显示文件和表单/消息

这种CURL请求在javaapi端点上被接受 在调试器中如下所示：

但是我在Python上的所有尝试，例如：

multipart_form_data_object = {
    'scrubbed.zip': (args.files[0], open(args.files[0], 'rb'), "application/json"),
    'files': (args.files[1], open(args.files[1], 'rb'), "application/json"),
    'message': (None, open(args.message, 'rb'), 'application/json')
}
 response = requests.post(args.url + ':' + str(args.port) + '/' + args.endpoint, files=multipart_form_data_object,
                             proxies=proxies)

（这是我得到的最接近工作的），看起来像这样：

multipart_form_data_object = {
    'scrubbed.zip': (args.files[0], open(args.files[0], 'rb'), "application/json"),
    'files': (args.files[1], open(args.files[1], 'rb'), "application/json"),
    'message': (None, open(args.message, 'rb'), 'application/json')
}
response = requests.post(args.url + ':' + str(args.port) + '/' + args.endpoint, files=multipart_form_data_object,
                         proxies=proxies)

其输出为：

{'Content-Length': '664', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'User-Agent': 'python-requests/2.21.0', 'Connection': 'keep-alive', 'Content-Type': 'multipart/form-data; boundary=227d4ef5a41db8a690e5cebadf336851'}
{
  "args": {},
  "data": "",
  "files": {
    "files": "ZIP-CONTENT-GOES-HERE",
    "scrubbed.zip": "ZIP-CONTENT-GOES-HERE22222"
  },
  "form": {
    "message": "{\r\n  \"runId\": \"9c4a-4c64f6d4d0ea\",\r\n  \"reports\": [\r\n    {\r\n      \"executionId\": \"d73-432a-b483-be404a13e8da\",\r\n      \"endTime\": \"\"\r\n    }\r\n  ]\r\n}"
  },
  "headers": {
    "Accept": "*/*",
    "Accept-Encoding": "gzip, deflate",
    "Connection": "keep-alive",
    "Content-Length": "664",
    "Content-Type": "multipart/form-data; boundary=227d4ef5a41db8a690e5cebadf336851",
    "Host": "java.api.host.com",
    "User-Agent": "python-requests/2.21.0"
  },
  "json": null,
  "method": "POST",
  "origin": "10.0.0.2",
  "url": "http://java.api.host.com/anything"
}

现在，尝试将其调整为发送一个文件数组（否则，如果我将

scrobed.zip

重命名为

files

，它将被覆盖），使其看起来像：

multipart_form_data_object = {
    'files': [(args.files[0], open(args.files[0], 'rb'), "application/json"),
     (args.files[1], open(args.files[1], 'rb'), "application/json")],
    'message': (None, open(args.message, 'rb'), 'application/json')
}

您的脚本应该如下所示：

multipart_form_data_object = {
    'scrubbed.zip': (args.files[0], open(args.files[0], 'rb'), "application/json"),
    'files': (args.files[1], open(args.files[1], 'rb'), "application/json"),
    'message': (None, open(args.message, 'rb'), 'application/json')
}
response = requests.post(args.url + ':' + str(args.port) + '/' + args.endpoint, files=multipart_form_data_object,
                         proxies=proxies)

注意：存在对

请求的依赖性\u toolbelt

发送.py

我使用django对其进行了测试：

url.py

称之为使用：

curl-shttp://127.0.0.1:8000/ -F“message=@$（pwd）/file1“-F”files=@$（pwd）/file2“-F”files=@$（pwd）/file3“

以及使用python

python send.py file1--files file2 file3

相同输出：

{"files": ["{\\"message\\": \\"hello world\\"}\\n", "something else\\n"], "message": ["hello world\\n"]}

谢谢结果证明，我上次尝试（列表）时的错误是元组中没有

消息。。一旦我这样做了，它就可以工作了：）我现在在将其转换为动态代码时遇到问题，这不起作用：
对于args.files中的report\u文件：file\u p=open（report\u file，'rb'）multipart\u list.append（'files'，（file\p.name，file\p，'application/zip）））multipart\u list.append（'message'，（None，open（args.message，'rb'）），'application/json'））
生成的错误是：
ValueError:无法对非2元组的对象进行编码
@Carmageddon很高兴听到这个消息，您能用完整的源代码提出一个新问题，并与我链接吗？我不记得它已经是什么了，解决了问题，也不记得是怎么解决的：）哦，好吧
