`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)¶

property 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).

property body_file_raw¶: Gets and sets the wsgi.input key in the environment.

property 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.

property url_encoding¶: Gets and sets the webob.url_encoding key in the environment.

property scheme¶: Gets and sets the wsgi.url_scheme key in the environment.

property method¶: Gets and sets the REQUEST_METHOD key in the environment.

property http_version¶: Gets and sets the SERVER_PROTOCOL key in the environment.

property content_length¶: Gets and sets the Content-Length header (HTTP spec section 14.13). Converts it using int.

property remote_user¶: Gets and sets the REMOTE_USER key in the environment.

property remote_host¶: Gets and sets the REMOTE_HOST key in the environment.

property remote_addr¶: Gets and sets the REMOTE_ADDR key in the environment.

property query_string¶: Gets and sets the QUERY_STRING key in the environment.

property server_name¶: Gets and sets the SERVER_NAME key in the environment.

property server_port¶: Gets and sets the SERVER_PORT key in the environment. Converts it using int.

property script_name¶: Gets and sets the SCRIPT_NAME key in the environment.

property path_info¶: Gets and sets the PATH_INFO key in the environment.

property uscript_name¶: Gets and sets the SCRIPT_NAME key in the environment.

property upath_info¶: Gets and sets the PATH_INFO key in the environment.

property 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.

property headers¶: All the request headers as a case-insensitive dictionary-like object.

property 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 is 192.168.1.1, 192.168.1.2, the value will be 192.168.1.1). If no HTTP_X_FORWARDED_FOR header is present in the environ at all, this attribute will return the value of the REMOTE_ADDR header. If the REMOTE_ADDR header 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_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 that HTTP_X_FORWARDED_FOR has the correct values. The WSGI server must be behind a trusted proxy for this to be true.

property 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 the HTTP_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 no HTTP_HOST header is present in the environ at all, this attribute will return the value of the SERVER_PORT header (which is guaranteed to be present).

property host_url¶: The URL through the host (no path)

property application_url¶: The URL including SCRIPT_NAME (no PATH_INFO or query string)

property path_url¶: The URL including SCRIPT_NAME and PATH_INFO, but not QUERY_STRING

property path¶: The path of the request, without host or query string

property path_qs¶: The path of the request, without host but with query string

property 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.

property urlvars¶

Return any named variables matched in the URL.

Takes values from environ['wsgiorg.routing_args']. Systems like routes set this value.

property urlargs¶

Return any positional variables matched in the URL.

Takes values from environ['wsgiorg.routing_args']. Systems like routes set this value.

property 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.

property host¶: Host name provided in HTTP_HOST, with fall-back to SERVER_NAME

property 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 the SERVER_NAME value in the environment if it doesn't. For example, if the environment contains an HTTP_HOST value of foo.example.com:8000, request.domain will 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.

property body¶: Return the content of the request body.

property json¶: Access the body of the request as JSON

property json_body¶: Access the body of the request as JSON

property text¶: Get/set the text value of the body

property 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.

property GET¶: Return a MultiDict containing all the variables from the QUERY_STRING.

property params¶: A dictionary-like object containing both the parameters from the query string and request body.

property cookies¶: 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.

property is_body_seekable¶: Gets and sets the webob.is_body_seekable key in the environment.

property 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.

property accept¶

Property representing the Accept header.

(RFC 7231, section 5.3.2)

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.)

property accept_charset¶

Property representing the Accept-Charset header.

(RFC 7231, section 5.3.3)

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.)

property accept_encoding¶

Property representing the Accept-Encoding header.

(RFC 7231, section 5.3.4)

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.)

property accept_language¶

Property representing the Accept-Language header.

(RFC 7231, section 5.3.5)

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.)

property authorization¶: Gets and sets the Authorization header (HTTP spec section 14.8). Converts it using parse_auth and serialize_auth.

property cache_control¶: Get/set/modify the Cache-Control header (HTTP spec section 14.9)

property if_match¶: Gets and sets the If-Match header (HTTP spec section 14.24). Converts it as a Etag.

property if_none_match¶: Gets and sets the If-None-Match header (HTTP spec section 14.26). Converts it as a Etag.

property date¶: Gets and sets the Date header (HTTP spec section 14.8). Converts it using HTTP date.

property if_modified_since¶: Gets and sets the If-Modified-Since header (HTTP spec section 14.25). Converts it using HTTP date.

property if_unmodified_since¶: Gets and sets the If-Unmodified-Since header (HTTP spec section 14.28). Converts it using HTTP date.

property if_range¶: Gets and sets the If-Range header (HTTP spec section 14.27). Converts it using IfRange object.

property max_forwards¶: Gets and sets the Max-Forwards header (HTTP spec section 14.31). Converts it using int.

property pragma¶: Gets and sets the Pragma header (HTTP spec section 14.32).

property range¶: Gets and sets the Range header (HTTP spec section 14.35). Converts it using Range object.

property referer¶: Gets and sets the Referer header (HTTP spec section 14.36).

property referrer¶: Gets and sets the Referer header (HTTP spec section 14.36).

property user_agent¶: Gets and sets the User-Agent 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 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 to self.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 to self.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__.
