Python 如何从flask restful API返回图像?
我想返回处理后的图像。到目前为止,我能够将映像发送到服务器和进程。如何返回图像以便任何客户端都可以使用Python 如何从flask restful API返回图像?,python,flask,flask-restful,Python,Flask,Flask Restful,我想返回处理后的图像。到目前为止,我能够将映像发送到服务器和进程。如何返回图像以便任何客户端都可以使用 class ImageProcessing(Resource): def __init__(self): parser = reqparse.RequestParser() parser.add_argument("image", type=werkzeug.datastructures.FileStorage, required
class ImageProcessing(Resource):
def __init__(self):
parser = reqparse.RequestParser()
parser.add_argument("image", type=werkzeug.datastructures.FileStorage, required=True, location='files')
self.req_parser = parser
def post(self):
image_file = self.req_parser.parse_args(strict=True).get("image", None)
if image_file:
image = image_file.read()
nparr = np.fromstring(image, np.uint8)
img = cv2.imdecode(nparr, cv2.IMREAD_COLOR)
img = process_img(img)
shape=img.shape
return "Image recieved: Image size {}X{}X{}".format(shape[0],shape[1],shape[2])
else:
return "Image sending failed"
卷曲url:
curl -X POST -F 'image=@data/test.jpg' http://127.0.0.1:5000/processImage
如何返回处理后的图像?没关系,我解决了这个问题,首先将图像转换为base64,然后将其作为字符串返回
rawBytes = io.BytesIO()
img.save(rawBytes, "JPEG")
rawBytes.seek(0)
img_base64 = base64.b64encode(rawBytes.read())
response = {
"shape": shape,
"image": img_base64.decode(),
"message":"Image is BASE 64 encoded"
}
return response,200
