HTTP POST image, how to interact with it?

[darrenleeleelee1]

Example

from fastapi import FastAPI, File, UploadFile
from fastapi.responses import FileResponse
from pydantic import BaseModel
import numpy as np
import shutil
app = FastAPI()


@app.get("/")
async def main():
    return FileResponse(r"misdo.jpg")


@app.post("/uploadfile/")
async def create_upload_file(image: UploadFile = File(...)):
    with open("destination.jpg", "wb") as buffer:
         shutil.copyfileobj(image.file, buffer)
    return image.filename`

Description

• This code is work fine in 127.0.0.1:8000/docs.

• But I am wondering how can I post without using 127.0.0.1:8000/docs.

• More specified is how could I use other languague(Swift) to interact with this API.

• I know how to do with HTTP.GET, but HTTP.POST still bothering me.

• Or is my POST funtion is not well defined?

Environment

• macOS
• FastAPI Version: 0.61.1
• Python version: 3.8.6

But I am wondering how can I post without using 127.0.0.1:8000/docs.

You can use cURL.

curl -X POST "http://127.0.0.1:8000/uploadfile/" -H  "Content-Type: multipart/form-data" -F "file=@your_file_name;type=image/jpeg"

I would use aiofiles with async with in /uploadfile.

import aiofiles

@app.post("/uploadfile/")
async def cache_favicon(file: UploadFile = File(...)):
    img = await file.read()
   
    async with aiofiles.open("destination.jpg" , "wb") as f:
        await f.write(img)
