在网上找的接口测试的代码，自己稍微修改了一下，

参数写成这样的时候

postparams = {'desc': {'areaCode': '010', 'username': u'立春', 'Password': '123456'},  'method': 'tutorLogin'}

报错如下：

Error
Traceback (most recent call last):
  File "E:\Users\Administrator\PycharmProjects\APITestDemo\TestMyLogin\TestLoginInter02.py", line 57, in test_call
    data = api.apicall('POST', 'http://180.76.139.233/ceshi/liveReportRest', getparams, postparams)
  File "E:\Users\Administrator\PycharmProjects\APITestDemo\TestMyLogin\TestLoginInter02.py", line 39, in apicall
    response = urllib2.urlopen(req)
  File "C:\Python27\lib\urllib2.py", line 154, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Python27\lib\urllib2.py", line 437, in open
    response = meth(req, response)
  File "C:\Python27\lib\urllib2.py", line 550, in http_response

    return self._call_chain(*args)

    result = func(*args)
  File "C:\Python27\lib\urllib2.py", line 558, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
HTTPError: HTTP Error 500: Internal Server Error

如果把立春前面的 u 去掉的时候

postparams = {'desc': {'areaCode': '010', 'username': '立春', 'Password': '123456'},  'method': 'tutorLogin'}

执行后的结果

{u'msg': u'\u7528\u6236\u540d\u3001\u5bc6\u7801\u9519\u8bef', u'rlt': u'false', u'totalPage': 0, u'code': u'000000', u'data': u''}

转成中文提示用户名密码错误，可是我用 jmeter 里面跑这个接口是能正常生成结果的，请看图片

最后贴上代码，各位大神帮忙看看问题出在哪里？用户名到底该怎样传入？
