Python 3.x FastAPI上载大于100kb的文件时出错

我正在尝试创建用于上载文件的端点。但是，如果文件大于100Kb，我会收到一个错误400错误请求。我的猜测是它没有足够的时间上传文件

我的函数的代码如下所示：

import uvicorn
from fastapi import FastAPI, File, UploadFile
import pathlib

app = FastAPI(title='Tool', description='Tool descr', version='0.0.1')

uploads = 'uploads'
uploads_dir = pathlib.Path(os.getcwd(), uploads)

@app.post('/api/upload/')
async def upload_file(file: UploadFile=File(...)):
    """
    Upload the file to be processed.
    """
    print(file)
    async with aiofiles.open(file.file, 'rb') as fin:
        exfile = fin.read() 
    file_name = pathlib.Path(uploads_dir, file.filename)
    async with aiofiles.open(f'{file_name}', 'wb') as f:
        await f.write(exfile)
    return {'filename': file.filename, 
                'content-type': file.content_type}

if __name__ == '__main__':
    uvicorn.run('main:app', host='127.0.0.1', port=5003, log_level='info')   

因此，如果是一个文本文件，或者如果是一个二进制文件，服务器会给我一个错误的请求答案，并在索引2处显示“未在边界末尾找到CR”，fo rexample

邮递员错误： { “详细信息”：“分析正文时出错” }

服务器返回的错误基本上如下所示：

这是一些请求，一些请求成功（文件大小约为50k），其他请求未作为“错误请求”处理。

将完整的错误回溯添加到操作系统。您找到解决方案了吗？是的，这是邮递员中的一个错误。我为这段代码创建了一个客户端，它成功了。我忘了更新它。
