-
-itchat是一个开源的微信个人号接口，使用python调用微信从未如此简单。
-
-使用不到三十行的代码，你就可以完成一个能够处理所有信息的微信机器人。
-
-当然，该api的使用远不止一个机器人，更多的功能等着你来发现，比如[这些][tutorial2]。
-
-如今微信已经成为了个人社交的很大一部分，希望这个项目能够帮助你扩展你的个人的微信号、方便自己的生活。
-
-## 安装
-
-可以通过本命令安装itchat：
-
-```python
-pip install itchat
-```
-
-## 简单入门实例
-
-有了itchat，如果你想要给文件传输助手发一条信息，只需要这样：
-
-```python
-import itchat
-
-itchat.auto_login()
-
-itchat.send('Hello, filehelper', toUserName='filehelper')
-```
-
-如果你想要回复发给自己的文本消息，只需要这样：
-
-```python
-import itchat
-
-@itchat.msg_register(itchat.content.TEXT)
-def text_reply(msg):
-    return msg['Text']
-
-itchat.auto_login()
-itchat.run()
-```
-
-一些进阶应用可以在下面的开源机器人的源码和进阶应用中看到，或者你也可以阅览[文档][document]。
-
-## 试一试
-
-这是一个基于这一项目的[开源小机器人][robot-source-code]，百闻不如一见，有兴趣可以尝试一下。

-@itchat.msg_register(TEXT, isGroupChat=True)
-def text_reply(msg):
-    if msg['isAt']:
-        itchat.send(u'@%s\u2005I received: %s' % (msg['ActualNickName'], msg['Content']), msg['FromUserName'])
-
-itchat.auto_login(True)
-itchat.run()
-```
-
-### 命令行二维码
-
-通过以下命令可以在登陆的时候使用命令行显示二维码：
-
-```python
-itchat.auto_login(enableCmdQR=True)
-```
-
-部分系统可能字幅宽度有出入，可以通过将enableCmdQR赋值为特定的倍数进行调整：
-
-```python
-# 如部分的linux系统，块字符的宽度为一个字符（正常应为两字符），故赋值为2
-itchat.auto_login(enableCmdQR=2)
-```
-
-默认控制台背景色为暗色（黑色），若背景色为浅色（白色），可以将enableCmdQR赋值为负值：
-
-```python
-itchat.auto_login(enableCmdQR=-1)
-```
-
-### 退出程序后暂存登陆状态
-
-通过如下命令登陆，即使程序关闭，一定时间内重新开启也可以不用重新扫码。
-
-```python
-itchat.auto_login(hotReload=True)
-```
-
-### 用户搜索
-
-使用`search_friends`方法可以搜索用户，有四种搜索方式：
-1. 仅获取自己的用户信息
-2. 获取特定`UserName`的用户信息
-3. 获取备注、微信号、昵称中的任何一项等于`name`键值的用户
-4. 获取备注、微信号、昵称分别等于相应键值的用户
-
-其中三、四项可以一同使用，下面是示例程序：
-
-```python
-# 获取自己的用户信息，返回自己的属性字典
-itchat.search_friends()
-# 获取特定UserName的用户信息
-itchat.search_friends(userName='@abcdefg1234567')
-# 获取任何一项等于name键值的用户
-itchat.search_friends(name='littlecodersh')
-# 获取分别对应相应键值的用户
-itchat.search_friends(wechatAccount='littlecodersh')
-# 三、四项功能可以一同使用
-itchat.search_friends(name='LittleCoder机器人', wechatAccount='littlecodersh')
-```
-
-关于公众号、群聊的获取与搜索在文档中有更加详细的介绍。
-
-### 附件的下载与发送
-
-itchat的附件下载方法存储在msg的Text键中。
-
-发送的文件的文件名（图片给出的默认文件名）都存储在msg的FileName键中。
-
-下载方法接受一个可用的位置参数（包括文件名），并将文件相应的存储。
-
-```python
-@itchat.msg_register(['Picture', 'Recording', 'Attachment', 'Video'])
-def download_files(msg):
-    msg['Text'](msg['FileName'])
-    itchat.send('@%s@%s'%('img' if msg['Type'] == 'Picture' else 'fil', msg['FileName']), msg['FromUserName'])
-    return '%s received'%msg['Type']
-```
-
-如果你不需要下载到本地，仅想要读取二进制串进行进一步处理可以不传入参数，方法将会返回图片的二进制串。
-
-```python
-@itchat.msg_register(['Picture', 'Recording', 'Attachment', 'Video'])
-def download_files(msg):
-    with open(msg['FileName'], 'wb') as f:
-        f.write(msg['Text']())
-```
-
-### 用户多开
-
-使用如下命令可以完成多开的操作：
-
-```python
-import itchat
-
-newInstance = itchat.new_instance()
-newInstance.auto_login(hotReload=True, statusStorageDir='newInstance.pkl')
-
-@newInstance.msg_register(TEXT)
-def reply(msg):
-    return msg['Text']
-
-newInstance.run()
-```
-
-### 退出及登陆完成后调用特定方法
-
-登陆完成后的方法需要赋值在`loginCallback`中。
-
-而退出后的方法需要赋值在`exitCallback`中。
-
-```python
-import time
-
-import itchat
-
-def lc():
-    print('finish login')
-def ec():
-    print('exit')
-
-itchat.auto_login(loginCallback=lc, exitCallback=ec)
-time.sleep(3)
-itchat.logout()
-```
-
-若不设置loginCallback的值，则将会自动删除二维码图片并清空命令行显示。
-

 当然这里需要特别强调的是三点，分别是短时间关闭重连、命令行二维码与自定义登陆内容。
 
 * itchat提供了登陆状态暂存，关闭程序后一定时间内不需要扫码即可登录。
+* 由于目前微信网页版提供上一次登录的微信号不扫码直接手机确认登陆，所以如果开启登陆状态暂存将会自动使用这一功能。
 * 为了方便在无图形界面使用itchat，程序内置了命令行二维码的显示。
 * 如果你需要就登录状态就一些修改（例如更改提示语、二维码出现后邮件发送等）。

 当然这里不需要深究为什么这些东西可以这么写，我在这里放出了示例程序只是为了给你一个该sdk相关代码大概样子的概念。
