Using web.py for REST webservices

[chaosmaker]

Hi all,


Someone knows if any version of web.py supports the PUT method or some
patch to support it?

I'm trying to use web.py for REST webservices, GET, POST and DELETE is
working fine, but I need the PUT method.


Thanks in advance

PUT should work fine. The default list of methods is:

./web/webapi.py: methods = ['GET', 'HEAD', 'POST', 'PUT', 'DELETE']

We can add more if anyone needs them.

I have tryed here to use the PUT method but the web.input() comes
empty.
And If I try to send the PUT request manualy after the PUT /URI HTTP/
1.0 the server closes my connection and don't accept the request body.

This is the only problem I have to use the web.py to implement one
webservice here.

web.input() only works if the incoming data is in key-value pairs;
usually with PUT you just get one big document so you need to call
web.data() instead.

Right but I can send the request body to the CherryPy because it
closes the connection before the client send the request body.

For example:

caquino@suruba:~/api$ telnet 127.0.0.1 8080
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
PUT /REST/v1/USER/Manage/username HTTP/1.0
Content-lenght: 245

HTTP/1.1 200 OK
Date: Tue, 05 Aug 2008 17:53:18 GMT
Server: CherryPy/3.0.1

Maybe if you spelled Content-Length correctly?

Works fine for me with 0.3:

$ telnet 0.0.0.0 8080
Trying 0.0.0.0...
Connected to 0.0.0.0.

Escape character is '^]'.

PUT / HTTP/1.0
Content-Length: 20

abcddddddddddddddd
HTTP/1.1 200 OK
Date: Tue, 05 Aug 2008 18:24:54 GMT
Server: CherryPy/3.1.0 WSGI Server

abcddddddddddddddd
Connection closed by foreign host.

You misspelled Content-length, which is probably the problem since
without it, the server doesn't know how much data to expect.

Sorry about the mistake, but for me using the right one give me the
same result.

But I have noticed one difference in your output
Server: CherryPy/3.0.1
Server: CherryPy/3.1.0 WSGI Server

I think this is the problem, I'm using the web.py from the debian
package, can this be the problem?

I have tryed to use the svn version, but the CherryPy used on it does
not work in the python 2.5 debian package because of some changes in
the cStringIO module.

[chaosmaker]

I'm sorry again, the web.data works with 3.0.1 too.
Sorry about bother.

Thanks for the help!

what is web.data()

[Yoan Blanc]

I had to do that modification for PUT:

=== modified file 'web/webapi.py'
--- web/webapi.py 2008-06-28 15:43:14 +0000
+++ web/webapi.py 2008-07-26 21:51:40 +0000
@@ -170,8 +170,8 @@
e = ctx.env.copy()
a = b = {}

- if _method.lower() in ['both', 'post']:
- if e['REQUEST_METHOD'] == 'POST':
+ if _method.lower() in ['both', 'post', 'put']:
+ if e['REQUEST_METHOD'] in ['POST', 'PUT']:
if e.get('CONTENT_TYPE', '').lower().startswith('multipart/'):
# since wsgi.input is directly passed to cgi.FieldStorage,
# it can not be called multiple times. Saving the FieldStorage

I dunno if it's the right way or if that has already been done elsewhere.

Isn't that in web.input? Are people PUTting form data? I guess that
could make sense; file a bug if that's what you're doing.

Already fixed.
