Python Microframework Bottle不起作用

Question

from bottle import route, run, get, request, static_file
import numpy as np
import pytesseract
from skimage.color import rgb2gray
from skimage import data
from skimage import io
from PIL import Image

def imageProcessing(image):
    img = io.imread(image)
    img = rgb2gray(img)
    io.imsave('sr.png', img)
    im = Image.open(static_file('sr.png', root='sr.png'))
    bg = Image.new("L", im.size, "white")
    print "made bg"
    bg.paste(im)
    txt = pytesseract.image_to_string(bg)
    return txt

@get('/a')
def test():
    url = request.get('url')
    if url:
        text = imageProcessing(url)       
        return {"url": url, "txt": text, "entities": arrayOfEntities}
    else:
        return {"url": url}

run(host='localhost', port=8080, reloader=True)

谁能向我解释为什么这行不通？ 我认为代码没有什么问题，我已经花了好几个小时研究了。 我可能是错的。

为什么总是返回“ url”：null？ 如何注册网址？

非常感谢。

您必须使用request.GET ：

@get('/a')
def test():
    url = request.GET.get('url')
    if url:
        text = imageProcessing(url)       
        return {"url": url, "txt": text, "entities": arrayOfEntities}
    else:
        return {"url": url}
