Như đã đề cập trước đây ở đây, cũng như ở đây và ở đây, người ta nên sử dụng

import requests

url = 'http://127.0.0.1:8000/upload'
file = {'file': open('images/1.png', 'rb')}
resp = requests.post(url=url, files=file) 
print(resp.json())

import requests

url = 'http://127.0.0.1:8000/upload'
file = {'file': open('images/1.png', 'rb')}
resp = requests.post(url=url, files=file) 
print(resp.json())

Phía máy chủ:

@app.post("/upload")
def upload(file: UploadFile = File(...)):
    try:
        contents = file.file.read()
        with open(file.filename, 'wb') as f:
            f.write(contents)
    except Exception:
        return {"message": "There was an error uploading the file"}
    finally:
        file.file.close()
        
    return {"message": f"Successfuly uploaded {file.filename}"}

phía khách hàng:

import requests

url = 'http://127.0.0.1:8000/upload'
file = {'file': open('images/1.png', 'rb')}
resp = requests.post(url=url, files=file) 
print(resp.json())

Tuy nhiên, nếu bạn vẫn cần gửi hình ảnh được mã hóa

import requests

url = 'http://127.0.0.1:8000/upload'
file = {'file': open('images/1.png', 'rb')}
resp = requests.post(url=url, files=file) 
print(resp.json())

url = 'http://127.0.0.1:8000/upload'
file = {'file': open('images/1.png', 'rb')}
resp = requests.post(url=url, files=file) 
print(resp.json())

phía khách hàng:

import base64
import requests

url = 'http://127.0.0.1:8000/upload'
with open("photo.png", "rb") as image_file:
    encoded_string = base64.b64encode(image_file.read())
    
payload ={"filename": "photo.png", "filedata": encoded_string}
resp = requests.post(url=url, data=payload)

Phía máy chủ:

@app.post("/upload")
def upload(filename: str = Form(...), filedata: str = Form(...)):
    image_as_bytes = str.encode(filedata)  # convert string to bytes
    img_recovered = base64.b64decode(image_as_bytes)  # decode base64string
    try:
        with open("uploaded_" + filename, "wb") as f:
            f.write(img_recovered)
    except Exception:
        return {"message": "There was an error uploading the file"}
        
    return {"message": f"Successfuly uploaded {filename}"}
