You want to create a custom exception handler in FastAPI that returns a JSON response with a dynamic message and a 400 status code whenever ValueError is raised. Which code snippet correctly implements this?
A from fastapi import FastAPI, Request
from fastapi.responses import JSONResponse
app = FastAPI()
@app.exception_handler(ValueError)
async def value_error_handler(request: Request, exc: ValueError):
return JSONResponse(content={"error": str(exc)}, status=400)
B from fastapi import FastAPI
app = FastAPI()
@app.exception_handler(ValueError)
def value_error_handler(exc: ValueError):
return {"error": str(exc), "status": 400}
C from fastapi import FastAPI, Request
app = FastAPI()
@app.add_exception_handler(ValueError)
async def value_error_handler(request: Request, exc: ValueError):
return {"error": str(exc), "status_code": 400}
D from fastapi import FastAPI, Request
from fastapi.responses import JSONResponse
app = FastAPI()
@app.exception_handler(ValueError)
async def value_error_handler(request: Request, exc: ValueError):
return JSONResponse(status_code=400, content={"error": str(exc)})
