About the size limitation of image

[sooit]

Hello:

Does anyone meet the problem of limitation of image?
I use web api to post an image for recognize. I use default web api with Paddleocr. But I got a response as below:

response code: 413
response code:

<title>413 Request Entity Too Large</title>

413 Request Entity Too Large

---

nginx/1.18.0 (Ubuntu)

Actually my picture is about 500K of file size, with 2166x1258 in pix size.

Can anyone help me on this? Thanks,

I install paddleocr following the guide. And use the following code to request for ocr service.

import requests
import json
import cv2
import base64

def cv2_to_base64(image):
data = cv2.imencode('.jpg', image)[1]
return base64.b64encode(data.tostring()).decode('utf8')

发送HTTP请求

data = {'images':[cv2_to_base64(cv2.imread("/PATH/TO/IMAGE"))]}
headers = {"Content-type": "application/json"}
url = "http://127.0.0.1:8866/predict/ch_pp-ocrv3"
r = requests.post(url=url, headers=headers, data=json.dumps(data))

打印预测结果

print(r.json()["results"])

I finally got the answer. That's because of nginx has limition on file size. I use install nginx before paddleocr. After I modify nginx.conf, this issue resolved.
