Try this.

header_content = {'Content-type': 'application/json'} 
js_data = json.dumps({'username': 'myusername', 
             'password': 'mypasswd',
             'callback':'jQuery17209257929018213263_1425826216682',
             'redirectURL':'http://www.10010.com',
             'redirectType':'01',
             'productType':'01',
             'pwdType':'01',
             'rememberMe':'01'})
response = requests.post(link, data=js_data, headers=header_content, verify=False)

if response.status_code == 200:
   print(response.content)

You need to specify content in the header, in your case it is json. Also, as you perform a request through https, certificate verification could cause a problem, so turn the verification off by "verify=False". Also error in json format could be a reason of 500, so to be sure that you are passing appropriate json object, I recommend to use json.dumps(). Hope it helps. Regards!
