Python请求：1个单一请求中的POST JSON和文件（多种数据）

从客户端（使用python），我想使用multiform-data作为单个请求的一部分发送json数据和文件，但无法实现这一点。在服务器端，我有Jersey，如果我使用curl发送请求，则工作正常，但如果使用Python发送相同的请求，则它不会起作用，因为Jersey崩溃。

python-requests软件包版本0.8.2-1。我无法升级到最新版本，因为这是ubuntu 12.04可用的最新版本。

低于curl的请求工作正常，服务器可以使用curl以下的请求成功处理请求。

curl -v -k -u "test:" -F file=@/tmp/test_new.zip --form upload_info='{"id": "1234", "test": "testing"}' -X POST "https://IP/test_api"

服务器端代码片段

    @POST
    @Path("/test_api")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.APPLICATION_JSON)
    public Response testAPIHandler(
                    @HeaderParam("Authorization") String auth,
                    @FormDataParam("file") InputStream uploadedInputStream,
                    @FormDataParam("file") FormDataContentDisposition fileDetail,
                    @FormDataParam("upload_info") JSONObject jsonData) throws IOException {
             try {
                    id = jsonData.getString("id");
                    url = jsonData.getString("test");
                 }

这是此python代码，但不起作用。甚至试图以相同的键名“ upload_info”将upload_info作为嵌套的json发送，这也不起作用。

def test_upload():
    url = "https://IP/api/test_api"
    user = "test"
    passwd = None
    upload_info = {'id': '1234', 'test': "testing"}
    filepath = "/tmp/test_new.zip"
    json_data = simplejson.dumps(upload_info)

    fileobj = open(filepath, 'rb')
    files = {'file' : ('test_new.zip', fileobj)}

    headers = {'Content-type': 'multipart/form-data'}
    r = requests.post(url, files=files, data=json_data, auth=(user, passwd), headers=headers)

    print r.status_code

test_upload()

当我使用Python发送请求时，服务器端出现此异常
