如何从python中修改html格式的文本 [英] how to modify text in html form from python
问题描述
我正在尝试从python更改表单字段中的数据。以下
代码不会崩溃，但没有效果，就好像形式一样只是
原始html表单的副本。
我必须重新创建表单才能这样做吗？
我的观点是客户能够重新读取修改后的数据。
谢谢，
Philippe
＃！/ usr / bin / python
导入cgi
导入os
导入系统
导入日志记录
import cgi
sys.stderr = sys.stdout
print" Content-type：text / html\\\
"
尝试：
form = cgi.FieldStorage（）
#logging.warning（表格）
除外：
logging.exception（" \ nEXCECEPTION 1"）
试试：
form [''tosrv ''] .value =" TEST"
除外：
logging.exception（" \ nEXCEPTION 2"）
pass

Hi,
I am trying to change the data in a form field from python. The following
code does not crash but has no effect as if "form" is just a copy of the
original html form.
Must I recreate the form order to do that ?
My point is for the client to be able to re-read the modified data.
Thanks,
Philippe

try:

pass

推荐答案
PS：如果我的问题目前尚不清楚，我正试图分享
客户端和服务器之间的形式。
就像许多站点允许您修改现有数据一样：
1 ）服务器弹出一个包含你数据的表格。
2）客户可以修改并提交。
我知道这是一个_basic_问题对不起。

just as many sites out there allow you to modify existing data:
1) the server pops up a form with your data in it.
2) the client can modify it and submit.
I know this is a _basic_ question, sorry.

什么时候调试Python cgi脚本，从
命令行运行脚本是有帮助的，以确保没有任何编译器错误。根据
如何设置服务器，如果你的
脚本不能编译，你会收到服务器错误或只是一个空白页面。当我按照我的建议直接运行你的脚本时，这就是我得到的
：
pmcnett @ sol：〜
When debugging Python cgi scripts, it is helpful to run the scripts from a
command line just to make sure there aren''t any compiler errors. Depending on
how the server is set up, you''ll get a server error or just a blank page if your
script won''t compile. When I run your script directly as I suggest, here''s what
I get:
pmcnett@sol:~
python test.py
文件" test.py"，第23行
< html>
^
语法错误：语法无效
D''哦！您需要用引号括住html以使其成为字符串，如：
print""
< html>
....
< / html>
"""
I我真的不明白你原来的问题，但也许这将有助于你再次滚动
。

python test.py
File "test.py", line 23
<html>
^
SyntaxError: invalid syntax
D''oh! You needed to surround the html with quotes to make it a string, as in:
print """
<html>
....
</html>
"""
I don''t really understand your original problem, but perhaps this will help get
you rolling again.
