Introduction📄

The bottle is a WSGI-compliant single source file web framework using only the Python standard library as its only external dependency (stdlib).

Introduction Image

The bottle is fantastic in the following web development scenarios:

🔥Idea prototyping

🔥Understanding the creation of web frameworks

🔥Creating and maintaining a straightforward personal web application

Request Object in Bottle Web Framework will be this blog's exclusive topic of discussion. Let's get straight into our discussion.

Request Object in Bottle Web Framework🌐

A WSGI environment is enclosed by the Request class, which also offers practical methods for accessing and parsing form data, cookies, file uploads, and other metadata. A large majority of the properties are read-only.

Request

alias of bottle.BaseRequest
Introduction Image

class BaseRequest(environ=None)

A WSGI environment dictionary wrapper includes several useful access methods and features of Request Object in Bottle Web Framework. They are primarily read-only. When additional attributes are added to a request, the environment dictionary actually adds them (under the name "bottle.request.ext.name>"). It is advised to store and access request-specific data in this manner.

Attributes in Request Object in Bottle Web Framework

⭐MEMFILE_MAX = 102400

Maximum size of the memory buffer for the body in bytes.

⭐environ

This is the only fundamental attribute. All other attributes are read-only properties.

⭐app

Bottle application handling this request.

⭐route

The bottle Route object that matches this request.

⭐url_args

The arguments are extracted from this argument.

⭐path

The value of thePATH_INFO with exactly one prefixed slash (to fix broken clients and avoid the "empty path" edge case). It's an essential attribute of Request Object in Bottle Web Framework.

⭐method

The REQUEST_METHOD value is to be an uppercase string.

⭐headers

A WSGIHeaderDict that provides case-insensitive access to the HTTP request headers.

⭐get_header(name, default=None)

Return the value of a request header or a given default value.

⭐cookies

Cookies parsed into a FormsDict. Signed cookies are NOT decoded. Use get_cookie() if you expect the signed cookies. It's an essential attribute of Request Object in Bottle Web Framework.

⭐get_cookie(key, default=none, secret=none, digestmod=< built-in function openssl_sha 256>)

Return the content of the cookie. To read a Signed Cookie, the argument secret has to match the one used to create the cookie earlier. (see BaseResponse.set_cookie()). Return a default value if anything goes against expectations(missing cookie or wrong signature). It's an important attribute of Request Object in Bottle Web Framework.

⭐query

FormsDict created from query string after parsing. Although they are commonly referred to as "URL arguments" or "GET parameters," these values should not be confused with "URL wildcards" because the Router provides them.

⭐forms

Form values extracted from a multipart/form-data encoded or url-encoded POST or PUT request body. AnFormsDict is the output that is returned. Strings make up all keys and values. Uploads of files are kept in files individually. It is a crucial component of the Bottle Web Framework's Request Object.

⭐params

A FormsDict contains the query and form values collectively. Files are where file uploads are kept.

⭐files

Parsing of file uploads from the body of multipart/form-data encoded PUT or GET requests. The values are FileUpload instances. It's a crucial component of the Bottle Web Framework's Request Object.

json

This property stores the content of the request body after it has been processed if the Content-Type header is of the type application/JSON or application/JSON-rpc. Only requests with file size smaller than MEMFILE MAX are executed to prevent memory exhaustion. JSON that isn't valid causes a 400 error response. It's an important attribute of Request Object in Bottle Web Framework.

⭐body

It is possible to seek through the HTTP request body. This is either a temporary file or an instance of io.BytesIO, depending on MEMFILE MAX. The wsgi.input environ variable is read and replaced when this property is first used. Later accesses just do a seek(0) on the file object. It's an essential attribute of Request Object in Bottle Web Framework.

⭐chunked

True if Chunked transfer encoding was.

⭐GET

An alias for the query.

⭐POST

The values of forms and files are combined into a single FormsDict. Values are either strings (form values) or instances of cgi.FieldStorage (file uploads). It’s an important attribute of Request Object in Bottle Web Framework.

⭐url

The complete request URL, including the hostname and scheme. Make sure the X-Forwarded-Host header ensures reliability if your app is protected by a reverse proxy or load balancer and you're experiencing inconsistent results. It is a crucial component of the Bottle Web Framework's Request Object.Framework.\

Request Object

⭐urlparts

The string in the URL is a urlparse. Tuple for SplitResult. Schema, host, path, query string, and fragment are all present in the tuple, but the fragment is never present because it is hidden from the server. It is a crucial component of the Bottle Web Framework's Request Object.

⭐fullpath

Request the full path, including the script_name (if present).

⭐query_string

The raw query part of the URL (everything in between ? and #) is a string.

⭐script_name

Before the application was called, a higher level (server or routing middleware) removed the initial part of the URL's path. Leading and trailing slashes are included in the script path that is returned. It's an essential attribute of Request Object in Bottle Web Framework.

⭐path_shift(shift=1)

  • Segments of the path should be shifted from the path to the script name and vice versa.
  • Parameters:
  • The number of path segments to shift is known as the shift. Changing the direction of the shift could be detrimental. (Default: 1)

 

⭐content_length

A number represents the intended body length. This header needs to be specified by the client. If not, -1 is returned, and the body's actual length is assumed to be unknown. The body would then be devoid. It's an essential attribute of Request Object in Bottle Web Framework.

⭐content_type

The Content-Type header is a lowercase string (default Value: Empty). 

⭐is_xhr

True if the request was triggered by an XMLHttpRequest. This only works with the JavaScript libraries that support the X-Requested-With header (most popular libraries do). It's an essential attribute of Request Object in Bottle Web Framework.

⭐is_ajax

Alias for is_xhr. "Ajax" is not the proper term.

⭐auth

As a (user, password) tuple is HTTP authentication data. Only basic authentication is supported by this time, by this implementation. The REMOTE USER environment variable searches the user field when authentication occurs at a higher level (such as the front web server or middleware). Any mistakes result in a return of None. It's an essential attribute of Request Object in Bottle Web Framework.

⭐remote_route

A list of all IPs involved in this request, starting with the client IP and followed by the zero or more proxies. This does only work if all the proxies support the `X-Forwarded-For header. Note that malicious clients can forge this information. It's an essential attribute of Request Object in Bottle Web Framework.

⭐remote_addr

The client IP is a string. Note that malicious clients can forge this information.

⭐copy()

Return a new Request with a shallow environ copy.

Bottle.request, which is implemented in LocalRequest at the module level, is a proxy object that always refers to the current request, or, to put it another way, the request that is now being handled by the request handler in the active thread. This thread locality makes it possible to use a global instance in a multi-threaded setting without risk.

⭐class LocalRequest(environ=None)

A thread-local subclass of BaseRequest has different attributes for each thread. There is usually one global instance of this class (request). If accessed during a request/response cycle, this instance always refers to the current request (even on a multi-threaded server). Just another attribute of Request Object in Bottle Web Framework.

⭐bind(environ=None)

Wrap a WSGI environ dictionary.

⭐environ

Thread-local property only.

⭐request = <LocalRequest: GET http://127.0.0.1/> or Local host

A thread-safe instance of the LocalRequest. If accessed from within a request callback, this instance always refers to the current request (even on a multi-threaded server).
