我的目的是在Google App Engine中部署Web服务。我使用CherryPy,因为我发现它很容易理解。
import sys
sys.path.insert(0,'cherrypy.zip')
import cherrypy
from cherrypy import expose
class Converter:
@expose
def index(self):
return "Hello World!"
@expose
def fahr_to_celc(self, degrees):
temp = (float(degrees) - 32) * 5 / 9
return "%.01f" % temp
@expose
def celc_to_fahr(self, degrees):
temp = float(degrees) * 9 / 5 + 32
return "%.01f" % temp
cherrypy.quickstart(Converter())
我想知道,如何以XML格式返回输出,比如
<?xml version="1.0" encoding="UTF-8"?>
<root>
<answer>Hello World!</answer>
</root>
我是Python的初学者。请帮助我。

我有类似的问题。我的解决方案是使用xml elementtree。这就像
....
#elementtree is stored in weird places... This catches most of em
try:
import xml.etree.ElementTree as ET # in python >=2.5
except ImportError:
try:
import cElementTree as ET # effbot's C module
except ImportError:
try:
import elementtree.ElementTree as ET # effbot's pure Python module
except ImportError:
try:
import lxml.etree as ET # ElementTree API using libxml2
except ImportError:
import warnings
warnings.warn("could not import ElementTree "
"(http://effbot.org/zone/element-index.htm)")
def build_xml_tree(answer_txt=""):
if not len(resources):
return ""
root = ET.Element("root")
answer = ET.SubElement(root, "answer")
answer.text = answer_txt
xml_string = ET.tostring(root)
return rxml_string
然后从你的函数中调用build_xml_tree
