How to List All Defined Url Paths In Fastapi?

To list all defined URL paths in FastAPI, you can use the app.routes attribute of the FastAPI application instance. This attribute returns a list of all the routes that have been defined in the application. You can iterate over this list to access the path and endpoint information of each route. This can be useful for debugging or documentation purposes to get a comprehensive overview of all the URL paths that your FastAPI application supports.

How can I view all the URLs and paths defined in FastAPI?

You can view all the URLs and paths defined in FastAPI by using the get_openapi function provided by FastAPI. This function generates an OpenAPI schema which includes all the defined URLs and paths.

Here is an example of how you can use the get_openapi function:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18

22

from fastapi import FastAPI
from fastapi.openapi.utils import get_openapi

app = FastAPI()

# Define your routes here

def custom_openapi():
    if app.openapi_schema:
        return app.openapi_schema
    openapi_schema = get_openapi(
        title="Custom title",
        version="2.5.0",
        description="This is a custom description of the OpenAPI schema",
        routes=app.routes
    )
    app.openapi_schema = openapi_schema
    return app.openapi_schema

app.openapi = custom_openapi

# You can now access the OpenAPI schema by visiting http://127.0.0.1:8000/docs

By accessing http://127.0.0.1:8000/docs, you can view the OpenAPI documentation which includes all the defined URLs and paths in your FastAPI application.

How do I retrieve all endpoint paths in FastAPI?

You can retrieve all endpoint paths in FastAPI by iterating through its app.router.routes attribute. Here's an example code snippet to achieve this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

from fastapi import FastAPI

app = FastAPI()

@app.get('/path1')
def get_path1():
    return {'message': 'Hello from path1'}

@app.post('/path2')
def post_path2():
    return {'message': 'Hello from path2'}

def get_all_endpoints():
    endpoints = []
    for route in app.routes:
        if 'name' in route.__dict__.keys() and route.name is not None:
            endpoints.append(route.path)
    return endpoints

all_endpoints = get_all_endpoints()
print(all_endpoints)

Running this code should output a list of all endpoint paths defined in your FastAPI application, which in this case would be ['/path1', '/path2'].

How to list all defined url paths in FastAPI using Python?

You can list all defined URL paths in FastAPI by accessing the app.routes attribute of your FastAPI app instance. Here is an example code snippet:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

from fastapi import FastAPI

app = FastAPI()

@app.get("/items/{item_id}")
async def read_item(item_id: int):
    return {"item_id": item_id}

@app.post("/items/")
async def create_item():
    return {"message": "Item created"}

# List all defined URL paths
for route in app.routes:
    print(route.path)

When you run this code, it will output the defined URL paths:

1
2

/items/{item_id}
/items/

This way, you can easily list all the defined URL paths in your FastAPI application.

How do I list all endpoints in FastAPI using Python?

You can list all endpoints in FastAPI by using the get_routes function available in the app object. Here is an example code snippet to demonstrate how to list all endpoints in FastAPI:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

from fastapi import FastAPI

app = FastAPI()

@app.get("/endpoint1")
async def endpoint1():
    return {"message": "Hello from Endpoint 1"}

@app.post("/endpoint2")
async def endpoint2():
    return {"message": "Hello from Endpoint 2"}

# Get all routes/endpoints
routes = app.routes

for route in routes:
    print(route.path, route.methods)

In this example, we have defined two endpoints /endpoint1 and /endpoint2 using the app.get and app.post decorators. We then use the app.routes attribute to get a list of all routes/endpoints in the FastAPI app. Finally, we iterate over each route object and print out the path and methods associated with each route.

By running this code, you will be able to see a list of all endpoints in your FastAPI application.

How can I view a list of all defined routes in FastAPI?

FastAPI does not have a built-in feature to display a list of all defined routes like some other frameworks do. However, you can manually list all the routes by iterating over the app.routes attribute of your FastAPI application instance. Here's an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

from fastapi import FastAPI

app = FastAPI()

# Define some routes
@app.get("/items/")
async def read_items():
    return {"message": "Read all items"}

@app.get("/items/{item_id}")
async def read_item(item_id: int):
    return {"message": f"Read item with ID {item_id}"}

# Print list of all defined routes
for route in app.routes:
    print(route.path)

This code snippet will print out the paths of all defined routes in your FastAPI application. You can customize the output to display additional information about each route if needed.
