使用一个非堵塞的socket用于接收http请求

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 = "<FUND_RECORD>\n"
    print(dic)
    if dic != None:
        for item in dic:
            xml += "<" + item + ">" + str(dic[item]) + "</" + item + ">\n"
    else:
        xml += "<rescode>0</rescode>\n<resmsg>未找到相关数据</resmsg>\n"
    xml += "</FUND_RECORD>"
    return xml
