python3.4.3 调用http接口 解析response xml后插入数据库

##连接sqlServer，获得请求xml，写入txt文件#########################

##循环得到的xml文件，逐个调用还款计划接口，解析后存到数据库##############

##请求接口数据#################

##将xml头的gb2312替换成utf-8###
print ('*'*20)

##将response生成xml文件#######
v_file_name = v_row_read[0] + '.xml'
f = open(v_file_name, 'w')
f.truncate()

f.write('\n')
f.close()

##读取xml####################
root=xml.etree.ElementTree.parse(v_file_name)
##连接数据库##################
connMAPP = cx_Oracle.connect("user","password","tnsname")

##将数据写入数据库#############
#book=root.findall('MX')
book=root.iter('MX')
for book_list in book:
#print ('='*20)
v_row = []
for note in book_list:
v_temp = v_row.append(note.text)

#print (v_sql)

##commit后关闭数据库连接
connMAPP.commit()
cur1.close()
connMAPP.close()
print ('Step3: ' +  time.strftime('%Y%m%d%H%M%S', time.localtime(time.time())))
