------------使用示例一：验证回调URL---------------
|
||||
*企业开启回调模式时，企业号会向验证url发送一个get请求
|
||||
假设点击验证时，企业收到类似请求：
|
||||
* GET /cgi-bin/wxpush?msg_signature=5c45ff5e21c57e6ad56bac8758b79b1d9ac89fd3×tamp=1409659589&nonce=263014780&echostr=P9nAzCzyDtyTWESHep1vC5X9xho%2FqYX3Zpb4yKa9SKld1DsH3Iyt3tP3zNdtp%2B4RPcs8TgAE7OaBO%2BFZXvnaqQ%3D%3D
|
||||
* HTTP/1.1 Host: qy.weixin.qq.com
|
||||
|
||||
接收到该请求时，企业应 1.解析出Get请求的参数，包括消息体签名(msg_signature)，时间戳(timestamp)，随机数字串(nonce)以及企业微信推送过来的随机加密字符串(echostr),
|
||||
这一步注意作URL解码。
|
||||
2.验证消息体签名的正确性
|
||||
3. 解密出echostr原文，将原文当作Get请求的response，返回给企业微信
|
||||
第2，3步可以用企业微信提供的库函数VerifyURL来实现。

||||

print("ERR: VerifyURL ret: " + str(ret))
|

sys.exit(1)

------------使用示例二：对用户回复的消息解密---------------
|
||||
用户回复消息或者点击事件响应时，企业会收到回调消息，此消息是经过企业微信加密之后的密文以post形式发送给企业，密文格式请参考官方文档
|
||||
假设企业收到企业微信的回调消息如下：
|
||||
POST /cgi-bin/wxpush? msg_signature=e3647471e395139e2308c1fa963f2d648a00b90e×tamp=1409659813&nonce=1372623149 HTTP/1.1

||||

||||

||||

|
||||
"agentid": 218
|
||||
}
|
||||
|
||||
企业收到post请求之后应该 1.解析出url上的参数，包括消息体签名(msg_signature)，时间戳(timestamp)以及随机数字串(nonce)
|
||||
2.验证消息体签名的正确性。 3.将post请求的数据进行json解析，并将"encrypt"标签的内容进行解密，解密出来的明文即是用户回复消息的明文，明文格式请参考官方文档
|
||||
第2，3步可以用企业微信提供的库函数DecryptMsg来实现。
|
||||
'''
|
||||
|
||||
sReqNonce = "1372623149"
|
||||
sReqTimeStamp = "1409659813"

|
||||
sReqMsgSig = "e3647471e395139e2308c1fa963f2d648a00b90e"

ret,sMsg=wxcpt.DecryptMsg( sReqData, sReqMsgSig, sReqTimeStamp, sReqNonce)

|

sys.exit(1)
|

||||
print(sMsg)

# 解密成功，sMsg即为json格式的明文
|
||||
# TODO: 对明文的处理

print("==============================")

|
||||
------------使用示例三：企业回复用户消息的加密---------------
|
||||
企业被动回复用户的消息也需要进行加密，并且拼接成密文格式的json串。
|
||||
假设企业需要回复用户的明文如下：
|
||||
|
||||
{
|
||||
"ToUserName": "mycreate",
|
||||
"FromUserName":"wx5823bf96d3bd56c7",
|
||||
"CreateTime": 1348831860,
|
||||
"MsgType": "text",
|
||||
"Content": "this is a test",
|
||||
"MsgId": 1234567890123456,
|
||||
"AgentID": 128
|
||||
}
|
||||
|
||||
为了将此段明文回复给用户，企业应： 1.自己生成时间时间戳(timestamp),随机数字串(nonce)以便生成消息体签名，也可以直接用从企业微信的post url上解析出的对应值。
|
||||
2.将明文加密得到密文。 3.用密文，步骤1生成的timestamp,nonce和企业在企业微信设定的token生成消息体签名。 4.将密文，消息体签名，时间戳，随机数字串拼接成json格式的字符串，发送给企业号。
|
||||
以上2，3，4步可以用企业微信提供的库函数EncryptMsg来实现。
|
||||
'''
|
||||
#sRespData = ' { "ToUserName": "mycreate", "FromUserName":"wx5823bf96d3bd56c7", "CreateTime": 1348831860, "MsgType": "text", "Content": "this is a test", "MsgId": 1234567890123456, "AgentID": 128 }';
|
||||
sRespData = '{ "ToUserName": "wx5823bf96d3bd56c7", "FromUserName": :mycreate", "CreateTime": 1409659813, "MsgType": "text", "Content": "hello", "MsgId": 4561255354251345929, "AgentID": 218}'
|
||||
ret,sEncryptMsg=wxcpt.EncryptMsg(sRespData, sReqNonce, sReqTimeStamp)
|
||||
if( ret!=0 ):
|
||||
print("ERR: EncryptMsg ret: " + str(ret))
|
||||
sys.exit(1)
|
||||
else:
|
||||
print(sEncryptMsg)
|
||||
#ret == 0 加密成功，企业需要将sEncryptMsg返回给企业号
|
||||
print("==============================")
|
||||
|
||||
'''
|
||||
对上面加密的包进行解密
|
||||
'''
|
||||
sReqMsgSig = json.loads(sEncryptMsg)['msgsignature']
|
||||
sReqTimeStamp = json.loads(sEncryptMsg)['timestamp']

sReqNonce = json.loads(sEncryptMsg)['nonce']
|
||||
|
||||
ret,sMsg=wxcpt.DecryptMsg( sEncryptMsg, sReqMsgSig, sReqTimeStamp, sReqNonce)
|
||||
if( ret!=0 ):
|
||||
print("ERR: DecryptMsg ret: " + str(ret))
