Question

我从模型中获得了dJango webform，其中包含一些错误检查（有效的电子邮件字段等）。在各种浏览器Opera，Camino，Netscape，Safari和IE（IE7除外）中一切正常。

我在IE7中获得的是“Internet Explorer无法显示网页”消息。如果表单有效，则数据将写入数据库，因此我认为它与重定向阶段有关。

我尝试过各种各样的方法= get和javascript表单提交，但似乎没有什么能阻止IE7给我这个错误。

任何帮助都将不胜感激。

Answer 1

通过替换

确认它是导致问题的重定向阶段

HttpResponseRedirect(url)

与

HttpResponse('<!DOCTYPE html><html><head><title>title</title></head><body><a href="%(url)s">%(url)s</a></body></html>' % {'url':url})

如果这不呈现，则问题发生在重定向之前。如果它确实呈现，那么问题可能是重定向，或者它可能是重定向的页面。点击链接。如果下一页显示正确，问题几乎肯定是重定向本身。否则，问题出在重定向页面中。
