-- Request¶
Request¶
-
class
webob.request.
Request
(environ, charset=None, unicode_errors=None, decode_param_names=None, **kw)¶ The default request implementation
-
class
webob.request.
BaseRequest
(environ, charset=None, unicode_errors=None, decode_param_names=None, **kw)¶ -
body_file
¶ Input stream of the request (wsgi.input). Setting this property resets the content_length and seekable flag (unlike setting req.body_file_raw).
-
body_file_raw
¶ Gets and sets the
wsgi.input
key in the environment.
-
body_file_seekable
¶ Get the body of the request (wsgi.input) as a seekable file-like object. Middleware and routing applications should use this attribute over .body_file.
If you access this value, CONTENT_LENGTH will also be updated.
-
url_encoding
¶ Gets and sets the
webob.url_encoding
key in the environment.
-
scheme
¶ Gets and sets the
wsgi.url_scheme
key in the environment.
-
method
¶ Gets and sets the
REQUEST_METHOD
key in the environment.
-
http_version
¶ Gets and sets the
SERVER_PROTOCOL
key in the environment.
-
content_length
¶ Gets and sets the
Content-Length
header (HTTP spec section 14.13). Converts it using int.
-
remote_user
¶ Gets and sets the
REMOTE_USER
key in the environment.
-
remote_host
¶ Gets and sets the
REMOTE_HOST
key in the environment.
-
remote_addr
¶ Gets and sets the
REMOTE_ADDR
key in the environment.
-
query_string
¶ Gets and sets the
QUERY_STRING
key in the environment.
-
server_name
¶ Gets and sets the
SERVER_NAME
key in the environment.
-
server_port
¶ Gets and sets the
SERVER_PORT
key in the environment. Converts it using int.
-
script_name
¶ Gets and sets the
SCRIPT_NAME
key in the environment.
-
path_info
¶ Gets and sets the
PATH_INFO
key in the environment.
-
uscript_name
¶ Gets and sets the
SCRIPT_NAME
key in the environment.
-
upath_info
¶ Gets and sets the
PATH_INFO
key in the environment.
-
content_type
¶ Return the content type, but leaving off any parameters (like charset, but also things like the type in
application/atom+xml; type=entry
)If you set this property, you can include parameters, or if you don't include any parameters in the value then existing parameters will be preserved.
-
headers
¶ All the request headers as a case-insensitive dictionary-like object.
-
client_addr
¶ The effective client IP address as a string. If the
HTTP_X_FORWARDED_FOR
header exists in the WSGI environ, this attribute returns the client IP address present in that header (e.g. if the header value is192.168.1.1, 192.168.1.2
, the value will be192.168.1.1
). If noHTTP_X_FORWARDED_FOR
header is present in the environ at all, this attribute will return the value of theREMOTE_ADDR
header. If theREMOTE_ADDR
header is unset, this attribute will return the valueNone
.Warning
It is possible for user agents to put someone else's IP or just any string in
HTTP_X_FORWARDED_FOR
as it is a normal HTTP header. Forward proxies can also provide incorrect values (private IP addresses etc). You cannot "blindly" trust the result of this method to provide you with valid data unless you're certain thatHTTP_X_FORWARDED_FOR
has the correct values. The WSGI server must be behind a trusted proxy for this to be true.
-
host_port
¶ The effective server port number as a string. If the
HTTP_HOST
header exists in the WSGI environ, this attribute returns the port number present in that header. If theHTTP_HOST
header exists but contains no explicit port number: if the WSGI url scheme is "https" , this attribute returns "443", if the WSGI url scheme is "http", this attribute returns "80" . If noHTTP_HOST
header is present in the environ at all, this attribute will return the value of theSERVER_PORT
header (which is guaranteed to be present).
-
host_url
¶ The URL through the host (no path)
-
application_url
¶ The URL including SCRIPT_NAME (no PATH_INFO or query string)
-
path_url
¶ The URL including SCRIPT_NAME and PATH_INFO, but not QUERY_STRING
-
path
¶ The path of the request, without host or query string
-
path_qs
¶ The path of the request, without host but with query string
-
url
¶ The full request URL, including QUERY_STRING
-
relative_url
(other_url, to_application=False)¶ Resolve other_url relative to the request URL.
If
to_application
is True, then resolve it relative to the URL with only SCRIPT_NAME
-
path_info_pop
(pattern=None)¶ 'Pops' off the next segment of PATH_INFO, pushing it onto SCRIPT_NAME, and returning the popped segment. Returns None if there is nothing left on PATH_INFO.
Does not return
''
when there's an empty segment (like/path//path
); these segments are just ignored.Optional
pattern
argument is a regexp to match the return value before returning. If there is no match, no changes are made to the request and None is returned.
-
path_info_peek
()¶ Returns the next segment on PATH_INFO, or None if there is no next segment. Doesn't modify the environment.
-
urlvars
¶ Return any named variables matched in the URL.
Takes values from
environ['wsgiorg.routing_args']
. Systems likeroutes
set this value.
-
urlargs
¶ Return any positional variables matched in the URL.
Takes values from
environ['wsgiorg.routing_args']
. Systems likeroutes
set this value.
-
is_xhr
¶ Is X-Requested-With header present and equal to
XMLHttpRequest
?Note: this isn't set by every XMLHttpRequest request, it is only set if you are using a Javascript library that sets it (or you set the header yourself manually). Currently Prototype and jQuery are known to set this header.
-
host
¶ Host name provided in HTTP_HOST, with fall-back to SERVER_NAME
-
domain
¶ Returns the domain portion of the host value. Equivalent to:
domain = request.host if ':' in domain and domain[-1] != ']': # Check for ] because of IPv6 domain = domain.rsplit(':', 1)[0]
This will be equivalent to the domain portion of the
HTTP_HOST
value in the environment if it exists, or theSERVER_NAME
value in the environment if it doesn't. For example, if the environment contains anHTTP_HOST
value offoo.example.com:8000
,request.domain
will returnfoo.example.com
.Note that this value cannot be set on the request. To set the host value use
webob.request.Request.host()
instead.
-
body
¶ Return the content of the request body.
-
json
¶ Access the body of the request as JSON
-
json_body
¶ Access the body of the request as JSON
-
text
¶ Get/set the text value of the body
-
POST
¶ Return a MultiDict containing all the variables from a form request. Returns an empty dict-like object for non-form requests.
Form requests are typically POST requests, however any other requests with an appropriate Content-Type are also supported.
-
GET
¶ Return a MultiDict containing all the variables from the QUERY_STRING.
-
params
¶ A dictionary-like object containing both the parameters from the query string and request body.
Return a dictionary of cookies as found in the request.
-
copy
()¶ Copy the request and environment object.
This only does a shallow copy, except of wsgi.input
-
copy_get
()¶ Copies the request and environment object, but turning this request into a GET along the way. If this was a POST request (or any other verb) then it becomes GET, and the request body is thrown away.
-
is_body_seekable
¶ Gets and sets the
webob.is_body_seekable
key in the environment.
-
is_body_readable
¶ webob.is_body_readable is a flag that tells us that we can read the input stream even though CONTENT_LENGTH is missing.
-
make_body_seekable
()¶ This forces
environ['wsgi.input']
to be seekable. That means that, the content is copied into a BytesIO or temporary file and flagged as seekable, so that it will not be unnecessarily copied again.After calling this method the .body_file is always seeked to the start of file and .content_length is not None.
The choice to copy to BytesIO is made from
self.request_body_tempfile_limit
-
copy_body
()¶ Copies the body, in cases where it might be shared with another request object and that is not desired.
This copies the body either into a BytesIO object (through setting req.body) or a temporary file.
-
make_tempfile
()¶ Create a tempfile to store big request body. This API is not stable yet. A 'size' argument might be added.
-
remove_conditional_headers
(remove_encoding=True, remove_range=True, remove_match=True, remove_modified=True)¶ Remove headers that make the request conditional.
These headers can cause the response to be 304 Not Modified, which in some cases you may not want to be possible.
This does not remove headers like If-Match, which are used for conflict detection.
-
accept
¶ Property representing the
Accept
header.The header value in the request environ is parsed and a new object representing the header is created every time we get the value of the property. (set and del change the header value in the request environ, and do not involve parsing.)
-
accept_charset
¶ Property representing the
Accept-Charset
header.The header value in the request environ is parsed and a new object representing the header is created every time we get the value of the property. (set and del change the header value in the request environ, and do not involve parsing.)
-
accept_encoding
¶ Property representing the
Accept-Encoding
header.The header value in the request environ is parsed and a new object representing the header is created every time we get the value of the property. (set and del change the header value in the request environ, and do not involve parsing.)
-
accept_language
¶ Property representing the
Accept-Language
header.The header value in the request environ is parsed and a new object representing the header is created every time we get the value of the property. (set and del change the header value in the request environ, and do not involve parsing.)
Gets and sets the
Authorization
header (HTTP spec section 14.8). Converts it usingparse_auth
andserialize_auth
.
-
cache_control
¶ Get/set/modify the Cache-Control header (HTTP spec section 14.9)

header (HTTP spec section 14.43).
-
as_bytes
(skip_body=False)¶ Return HTTP bytes representing this request. If skip_body is True, exclude the body. If skip_body is an integer larger than one, skip body only if its length is bigger than that number.
-
classmethod
from_bytes
(b)¶ Create a request from HTTP bytes data. If the bytes contain extra data after the request, raise a ValueError.
-
classmethod
from_file
(fp)¶ Read a request from a file-like object (it must implement
.read(size)
and.readline()
).It will read up to the end of the request, not the end of the file (unless the request is a POST or PUT and has no Content-Length, in that case, the entire file is read).
This reads the request as represented by
str(req)
; it may not read every valid HTTP request properly.
-
call_application
(application, catch_exc_info=False)¶ Call the given WSGI application, returning
(status_string, headerlist, app_iter)
Be sure to call
app_iter.close()
if it's there.If catch_exc_info is true, then returns
(status_string, headerlist, app_iter, exc_info)
, where the fourth item may be None, but won't be if there was an exception. If you don't do this and there was an exception, the exception will be raised directly.
-
ResponseClass
¶ alias of
webob.response.Response
-
send
(application=None, catch_exc_info=False)¶ Like
.call_application(application)
, except returns a response object with.status
,.headers
, and.body
attributes.This will use
self.ResponseClass
to figure out the class of the response object to return.If
application
is not given, this will send the request toself.make_default_send_app()
-
get_response
(application=None, catch_exc_info=False)¶ Like
.call_application(application)
, except returns a response object with.status
,.headers
, and.body
attributes.This will use
self.ResponseClass
to figure out the class of the response object to return.If
application
is not given, this will send the request toself.make_default_send_app()
-
classmethod
blank
(path, environ=None, base_url=None, headers=None, POST=None, **kw)¶ Create a blank request environ (and Request wrapper) with the given path (path should be urlencoded), and any keys from environ.
The path will become path_info, with any query string split off and used.
All necessary keys will be added to the environ, but the values you pass in will take precedence. If you pass in base_url then wsgi.url_scheme, HTTP_HOST, and SCRIPT_NAME will be filled in from that value.
Any extra keyword will be passed to
__init__
.
