具體來說，我希望下面的示例能夠作業：
應用程式.py
from fastapi import FastAPI,File,UploadFile,Form,Body
import uvicorn
app = FastAPI()
@app.get("/")
async def root():
return {"message": "Hello World"}
@app.get("/hello/{name}")
async def say_hello(name: str):
return {"message": f"Hello {name}"}
@app.post("/jsk")
async def save_image_meta(farm_name: str = Form(...), files: UploadFile = File(...)):
print('*'*100)
return {
"farm_name": farm_name
}
if __name__ == "__main__":
uvicorn.run("main:app", host="127.0.0.1", port=8088, reload=True)
如果這不是 POST 請求的正確方法，請告訴我如何從 FastAPI 中上傳的影像檔案中選擇所需的列。
測驗.py
import base64
import hmac
import json
import requests
def parse_params_to_str(params):
url = "?"
for key, value in params.items():
url = url str(key) '=' str(value) '&'
return url[1:-1]
def hash_string(qs, secret_key):
mac = hmac.new(bytes(secret_key, encoding='utf8'), bytes(qs, encoding='utf-8'), digestmod='sha256')
d = mac.digest()
validating_secret = str(base64.b64encode(d).decode('utf-8'))
return validating_secret
def sample_request():
access_key = "dfaa65a6-ee25-4b03-916b-bedb9095-35f9-4485-a72e-5da4e161a12b"
secret_key = "GWpnn56bUOnCedhpiUWYJl9dtZ3WllWtUeBUGQva"
qs = dict(key=access_key)
header_secret = hash_string(parse_params_to_str(qs), secret_key)
url = f"http://127.0.0.1:8088/jsk"
headers = {
'Content-Type': 'multipart/form-data',
'Accept': 'application/json',
'secret': header_secret
}
file = "/Users/jskim/Downloads/111111.jpg"
files = {'files': open(file, 'rb')}
payload = {"farm_name": "11111"}
res = requests.post(url, data=payload, headers=headers, files=files)
return res
sample_request()
我收到 400 錯誤請求錯誤。幫助。
如果這不是 POST 請求的正確方法，請告訴我如何從 FastAPI 中上傳的影像檔案中選擇所需的列。
uj5u.com熱心網友回復：
您不應該Content-Type multipart/form-data自己定義標題。庫requests通過定義邊界來自動處理這個問題。如果您自己設定此標頭，requests則不會這樣做，并且您的服務器將不知道預期的邊界（除非您決定自己也設定邊界）。
要作業，您的標題應該沒有內容型別：
headers = {
'Accept': 'application/json',
secret: header_secret
}

我會給你我在我的專案中所做的，我希望它會幫助你
它基本但很有幫助
