self.breedInfoDl = None
self.breedInfo = None
self.provice = None

registerClassAlias("personTypeAlias", Person);

注册自定义的Body参数类型，这样数据类型com.itown.kas.pfsc.report.po.HqPara就会在后面被一并发给服务端（否则服务端就可能返回参数不是预期的异常Client.Message.Deserialize.InvalidType）

pyamf.register_class(HqPara, alias='com.itown.kas.pfsc.report.po.HqPara')

构造flex.messaging.messages.RemotingMessage消息

msg = messaging.RemotingMessage(messageId=str(uuid.uuid1()).upper(),
clientId=str(uuid.uuid1()).upper(),
operation='getHqSearchData',
destination='reportStatService',
timeToLive=0,
timestamp=0)

第一个是查询参数，第二个是页数，第三个是控制每页显示的数量（默认每页只显示15条）

构造请求数据

def getRequestData(page_num,total_num):
msg.body = [HqPara(),str(page_num), str(total_num)]
msg.headers['DSEndpoint'] = None
msg.headers['DSId'] = str(uuid.uuid1()).upper()
# 按AMF协议编码数据
req = remoting.Request('null', body=(msg,))
env = remoting.Envelope(amfVersion=pyamf.AMF3)
env.bodies = [('/1', req)]
data = bytes(remoting.encode(env).read())
return data

获取响应源数据

def getResponse(data):
url = 'http://jgsb.agri.cn/messagebroker/amf'
req = request.Request(url, data, headers={'Content-Type': 'application/x-amf'})
# 解析返回数据
opener = request.build_opener()
return opener.open(req).read()

解析d

def getContent(response):
amf_parse_info = remoting.decode(response)
# 数据总条数
total_num = amf_parse_info.bodies[0][1].body.body[3]
info = amf_parse_info.bodies[0][1].body.body[0]
return total_num, info
def store2json(info):
res = []
for record in info:
record['reportDate'] = record['reportDate'].strftime('%Y-%m-%d %H:%M:%S')
record['auditDate'] = record['auditDate'].strftime('%Y-%m-%d %H:%M:%S')
res.append(record)
fp = open('info.json','w')
json.dump(res,fp,indent=4)
fp.close()

测试

reqData = getRequestData(1,15)
rep = getResponse(reqData)
total_num,info = getContent(rep)

reqData = getRequestData(1,total_num)
rep = getResponse(reqData)
total_num,info = getContent(rep)
store2json(info)
