Request

gradio.Request(···)

Description

A Gradio request object that can be used to access the request headers, cookies, query parameters and other information about the request from within the prediction function. The class is a thin wrapper around the fastapi.Request class. Attributes of this class include: headers, client, query_params, session_hash, and path_params. If auth is enabled, the username attribute can be used to get the logged in user.

Example Usage

import gradio as gr
def echo(text, request: gr.Request):
    if request:
        print("Request headers dictionary:", request.headers)
        print("IP address:", request.client.host)
        print("Query parameters:", dict(request.query_params))
        print("Session hash:", request.session_hash)
    return text
io = gr.Interface(echo, "textbox", "textbox").launch()

Initialization

Demos

import gradio as gr

def predict(text, request: gr.Request):
    headers = request.headers
    host = request.client.host
    user_agent = request.headers["user-agent"]
    return {
        "ip": host,
        "user_agent": user_agent,
        "headers": headers,
    }

gr.Interface(predict, "text", "json").launch()
