需求：客户需要通过HTTP请求（URL）方式访问子系统，用于请求XXX数据，返回XML数据格式。
方案：使用一个python脚本来起一个socket服务，用于客户来访问该服务获取数据。
代码如下：
以下代码处理两个不同的客户访问我们服务，上下文分别为/doTrader 一个返回json字符串 /wjdInterface 一个返回XML报文
def doTrader(paramXml, httpUrl):
xxxxxx
return json.dumps(results)
def wjdInterface(paramXml, httpUrl):
xxxxx
res_xml = makeXmlForHandle(results)
return res_xml
# 将对象编辑成XML报文格式
def makeXmlForHandle(dic):
xml = "\n" "
print(dic)
if dic != None:
for item in dic:
xml += "<" + item + ">" + str(dic[item]) + "\n"
else:
xml += "0 \n未找到相关数据 \n"
xml += "
return xml
