请教各位，python 用post请求登陆，使用的是json，没弄明白！
import httplib
import json
import urllib
conn = httplib.HTTPConnection("http://192.168.1.104:8080")
headers = {"Content-type":"application/json"}
param = ({"type":"2","loginName":"13983643100","password":"6aa5e3cc0678b335a9547f60045baa6b","systemVersion":"6.1.2"})
conn.request("POST" ,"/linkup_base/user/login.mlk",json.JSONEncoder().encode(param), headers)
response = conn.getresponse()
data = response.read(200000)
print(data)
conn.close() 刚刚学习python,提交到服务器报错，如下
Traceback (most recent call last):

写回答
其实这个问题是因为我自己没有注意post请求，下面是代码
importjsonimporturllib2,urllibparams=urllib.urlencode({'param':json.dumps({'type':'2','loginName':'13983643158','password':'6aa5e3cc0678b335a9547f60045baa6b','systemVersion':'6.1.2'})})printparamsf=urllib.urlopen("http://192.168.1.104:8080/line/user/login.mlk",params)data=f.read()print(data)ddata=json.loads(data)print(ddata)type(ddata)print(ddata['data'])httplib.HTTPConnection(host[,port[,strict[,timeout]]])
看,手册!!!!!!!!!!!!!!!!!!!!!!!!!
conn.close()
--------------------------------------------------------
没注意你用json的方式提交的,不过不影响,给你改改.......错误出在httpconnection那块了,不要带http://这样的东西
{"state":-1,"msg":"登录信息为空"}返回的时候数据是这样的，不知道是不是data设置不对！我之前都是直接用urllib2，还是比http更方便的。
