在特定路径上写入文件的问题

Question

我尝试通过指定要保存的文件夹路径将文件写入磁盘。但是按指定路径读取文件报错

FileNotFoundError: [Errno 2] No such file or directory: '/home/jekson/Projects/img-text-reco/static/product_images/24f2a9d0372a49bc8c5eb259798477f0.jpeg'

这一行出现错误。

async with aiofiles.open(os.path.join(IMG_DIR, file_name)) as f

为清楚起见，我进行了打印调用，指示主体函数中的路径

from db import BASEDIR

print(BASEDIR) # /home/jekson/Projects/img-text-reco

def file_upload():
    ....
    IMG_DIR = os.path.join(BASEDIR, 'static/product_images')
    if not os.path.exists(IMG_DIR):
        os.makedirs(IMG_DIR)
    print(f'IMG_DIR {IMG_DIR}') # IMG_DIR /home/jekson/Projects/img-text-reco/static/product_images
    content = await file.read()
    if file.content_type not in ['image/jpeg', 'image/png']:
        raise HTTPException(status_code=406, detail="Only .jpeg or .png  files allowed")
    file_name = f'{uuid.uuid4().hex}{ext}'
    print(os.path.join(IMG_DIR, file_name)) # /home/jekson/Projects/img-text-reco/static/product_images/24f2a9d0372a49bc8c5eb259798477f0.jpeg
    async with aiofiles.open(os.path.join(IMG_DIR, file_name)) as f:
        await f.write(content)
    path_to_img = os.path.abspath(os.path.join(IMG_DIR, file_name))
    ....

您打开文件进行阅读，但它不存在，因此出现错误。以下 f.write 建议您改为打开文件进行写入：

async with aiofiles.open(os.path.join(IMG_DIR, file_name), mode='w') as f:
