webob.request -- 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)¶
- 
GET¶
- Return a MultiDict containing all the variables from the QUERY_STRING. 
 - 
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 PUT & PATCH requests with an appropriate Content-Type are also supported. 
 - 
ResponseClass¶
- alias of - Response
 - 
accept¶
- Gets and sets the - Acceptheader (HTTP spec section 14.1).
 - 
accept_charset¶
- Gets and sets the - Accept-Charsetheader (HTTP spec section 14.2).
 - 
accept_encoding¶
- Gets and sets the - Accept-Encodingheader (HTTP spec section 14.3).
 - 
accept_language¶
- Gets and sets the - Accept-Languageheader (HTTP spec section 14.4).
 - 
application_url¶
- The URL including SCRIPT_NAME (no PATH_INFO or query string) 
 - 
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. 
 - Gets and sets the - Authorizationheader (HTTP spec section 14.8). Converts it using- parse_authand- serialize_auth.
 - 
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__.
 - 
body¶
- Return the content of the request body. 
 - 
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.inputkey 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. 
 - 
cache_control¶
- Get/set/modify the Cache-Control header (HTTP spec section 14.9) 
 - 
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.
 - 
client_addr¶
- The effective client IP address as a string. If the - HTTP_X_FORWARDED_FORheader exists in the WSGI environ, this attribute returns the client IP address present in that header (e.g. if the header value is- 192.168.1.1, 192.168.1.2, the value will be- 192.168.1.1). If no- HTTP_X_FORWARDED_FORheader is present in the environ at all, this attribute will return the value of the- REMOTE_ADDRheader. If the- REMOTE_ADDRheader is unset, this attribute will return the value- None.- Warning - It is possible for user agents to put someone else's IP or just any string in - HTTP_X_FORWARDED_FORas 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 that- HTTP_X_FORWARDED_FORhas the correct values. The WSGI server must be behind a trusted proxy for this to be true.
 - 
content_length¶
- Gets and sets the - Content-Lengthheader (HTTP spec section 14.13). Converts it using int.
 - 
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. 
 - 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_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. 
 - 
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. 
 - 
date¶
- Gets and sets the - Dateheader (HTTP spec section 14.8). Converts it using HTTP date.
 - 
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_HOSTvalue in the environment if it exists, or the- SERVER_NAMEvalue in the environment if it doesn't. For example, if the environment contains an- HTTP_HOSTvalue of- foo.example.com:8000,- request.domainwill return- foo.example.com.- Note that this value cannot be set on the request. To set the host value use - webob.request.Request.host()instead.
 - 
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.
 - 
get_response(application=None, catch_exc_info=False)¶
- Like - .call_application(application), except returns a response object with- .status,- .headers, and- .bodyattributes.- This will use - self.ResponseClassto figure out the class of the response object to return.- If - applicationis not given, this will send the request to- self.make_default_send_app()
 - 
headers¶
- All the request headers as a case-insensitive dictionary-like object. 
 - 
host¶
- Host name provided in HTTP_HOST, with fall-back to SERVER_NAME 
 - 
host_port¶
- The effective server port number as a string. If the - HTTP_HOSTheader exists in the WSGI environ, this attribute returns the port number present in that header. If the- HTTP_HOSTheader 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 no- HTTP_HOSTheader is present in the environ at all, this attribute will return the value of the- SERVER_PORTheader (which is guaranteed to be present).
 - 
host_url¶
- The URL through the host (no path) 
 - 
http_version¶
- Gets and sets the - SERVER_PROTOCOLkey in the environment.

- Gets and sets the - If-Rangeheader (HTTP spec section 14.27). Converts it using IfRange object.
 - 
if_unmodified_since¶
- Gets and sets the - If-Unmodified-Sinceheader (HTTP spec section 14.28). Converts it using HTTP date.
 - 
is_body_readable¶

 - 
is_body_seekable¶
- Gets and sets the - webob.is_body_seekablekey in the environment.
 - 
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. 
 - 
json¶
- Access the body of the request as JSON 
 - 
json_body¶
- Access the body of the request as JSON 
 - 
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
 - 
make_tempfile()¶
- Create a tempfile to store big request body. This API is not stable yet. A 'size' argument might be added. 
 - 
max_forwards¶

 - 
path_info_peek()¶
- Returns the next segment on PATH_INFO, or None if there is no next segment. Doesn't modify the environment. 
 - 
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 - patternargument 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_qs¶
- The path of the request, without host but with query string 
 - 
path_url¶
