我正在尝试使用请求将 JSON 数据 + 文件(二进制)上传到 FastAPI 'POST' 端点。
这是服务器代码:
@app.post("/files/")
async def create_file(
file: bytes = File(...), fileb: UploadFile = File(...), timestamp: str = Form(...)
):
return {
"file_size": len(file),
"timestamp": timestamp,
"fileb_content_type": fileb.content_type,
}
这是客户端代码:
session = requests.Session()
adapter = requests.adapters.HTTPAdapter(max_retries=0)
session.mount('http://', adapter)
jpg_image = open(IMG_PATH, 'rb').read()
timestamp_str = datetime.datetime.now().isoformat()
files = {
'timestamp': (None, timestamp_str),
'file': ('image.jpg', jpg_image),
}
request = requests.Request('POST',
FILE_UPLOAD_ENDPOINT,
files=files)
prepared_request = request.prepare()
response = session.send(prepared_request)
服务器失败
“POST /files/HTTP/1.1”422 无法处理的实体
