Question

我有以下脚本 -

count = 1
for line in temp:
    if (str(count) + '=') in line:
        job = re.findall(re.escape('=')+"(.*)",line)[0]

        fullsrcurl = self.srcjson + '?format=xml&jobname=' + job
        srcfile = urllib2.urlopen(fullsrcurl)
        srcdoc = etree.parse(srcfile)
        srcdata = etree.tostring(srcdoc, pretty_print=True)
        srcjobmst_id = srcdoc.xpath('//jobmst_id/text()')[0]
        srcxml = 'c:\\temp\\deployments\\%s\\%s.xml' % (source_env, srcjobmst_id)
        srcxmlsave = open(srcxml, 'w')
        srcxmlsave.write(srcdata)
        srcxmlsave.close

        fulldsturl = self.targetjson + '?format=xml&jobname=' + job
        dstfile = urllib2.urlopen(fulldsturl)
        dstdoc = etree.parse(dstfile)
        dstdata = etree.tostring(dstdoc, pretty_print=True)
        dstjobmst_id = dstdoc.xpath('//jobmst_id/text()')[0]
        dstxml = 'c:\\temp\\deployments\\%s\\%s.xml' % (target_env, dstjobmst_id)
        dstxmlsave = open(dstxml, 'w')
        dstxmlsave.write(dstdata)
        dstxmlsave.close

        print "Job = " + job
        count += 1

它在2个环境中点击2个独立的API，但数据几乎完全相同。源工作正常，一旦它尝试对目标数据做任何事情我得到了跟随错误 -

所以目标/目标xml必须有不同之处，但我很难理解什么。当我在浏览器中查看这两个值时，除了一些值（jobmst_id）之外，它们是相同的

Answer 1

您没有关闭文件。将srcxmlsave.close更改为srcxmlsave.close()或使用上下文管理器，如

with open(srcxml, 'w') as srcxmlsave:
    srcxmlsave.write(srcdata)

Answer 2

如果有人在将来遇到这样的问题，我发现了问题，它与lxml或xml生成无关。我的源环境已使用mod_wsgi进行了生产，但目标环境仍在使用runserver。

我猜编码中的某些东西会破坏目标。我只是生产了目标环境并且工作正常。

python lxml保存不工作
