我正在尝试使用 IronPython 2.7.4 使用该urllib2模块发出带有数据和标头的基本 HTTP 请求。由于一些原因，我无法使用 IronPython 2.7.5，因此无法安装这个可爱的requests模块——据我所知，它与早期版本不兼容——所以我坚持使用urllib2.

我的代码似乎在该response = urllib2.urlopen(request)行失败：

import json
import urllib2
import logging

#Create log for long-ass error
LOG_FILENAME = 'error.txt'
logging.basicConfig(filename=LOG_FILENAME, level=logging.DEBUG)


try:
    #Main Function
    data = json.dumps({"userID": "user@companycom", "password": "abcd1234"})
    header = {"Content-Type": "application/json"}
    request = urllib2.Request("https://company.autodeskplm360.net/rest/auth/1/login")
    request.add_header("Content-Type", "application/json")
    request.add_data(data)
    response = urllib2.urlopen(request)
    print(response)
#Print long-ass error to file
except:
    logging.exception("THIS IS MY ERROR")
    raise

我收到以下冗长的错误...有什么建议吗？

ERROR:root:THIS IS MY ERROR

编辑：解决了问题！

在 IronPython 文档中发现了一个不同的请求类型库，它使用 .NET 类WebRequest修改了稍微显示的示例函数以说明 JSON 和 blammo。200 OK产生的响应。
