Certainly! To send a Starlette FormData data structure to a FastAPI endpoint using the Python requests library, you can follow the steps outlined below. This tutorial assumes you have FastAPI and requests library installed. If not, you can install them using:
Here is a step-by-step tutorial:
Create a FastAPI app with an endpoint that accepts FormData. Save it in a file named main.py:
This simple example defines an endpoint /upload that takes a name and a file as form data.
In your Python script or Jupyter notebook, import the required modules:
Create a MultipartEncoder instance to encode the FormData:
Replace 'file.txt' with the actual file path you want to upload.
Set the necessary headers for the request:
Use the requests.post method to send the FormData to the FastAPI endpoint:
Replace 'http://localhost:8000/upload' with the actual URL where your FastAPI server is running.
Handle the response from the server:
This checks if the response status code is 200 (OK) and prints the JSON response. If the status code is not 200, it prints the error message.
Putting it all together, your Python script might look like this:
Replace 'file.txt' with the actual file path and 'http://localhost:8000/upload' with your FastAPI server's URL.
Remember to start your FastAPI server before running this script. You can do this by running:
Now, when you run your Python script, it should send FormData to your FastAPI endpoint.
