Python 3.x 谷歌云功能没有返回响应

Python 3.x 谷歌云功能没有返回响应,python-3.x,curl,flask,google-cloud-platform,google-cloud-functions,Python 3.x,Curl,Flask,Google Cloud Platform,Google Cloud Functions,我在谷歌云函数https://ocr.space/ocrapi 这是我部署的功能 def ocr_space_url(request): request_json = request.get_json() request_args = request.args if request_json and 'url' in request_json: url = request_json['url'] elif request_args and '

我在谷歌云函数
https://ocr.space/ocrapi
这是我部署的功能

def ocr_space_url(request):
    request_json = request.get_json()
    request_args = request.args


    if request_json and 'url' in request_json:
        url = request_json['url']

    elif request_args and 'url' in request_args: 
        url = request_args['url']
    else:
        url = 'http://www.africau.edu/images/default/sample.pdf'

    headers = {
        'apikey': 'helloworld',
    }
     payload = {'url': url,
               }
    r = requests.post('https://api.ocr.space/parse/image',
                      headers=headers, data=payload,
                      )

    return r.content.decode()

这样部署:
gcloud函数部署ocr\u space\u url——运行时Python 37——触发http


调用方法:
curl-X POST”https://us-central1-prefab-environs-241910.cloudfunctions.net/ocr_space_url“-H”内容类型:application/json“-d”{“url”:”http://dl.a9t9.com/ocrbenchmark/pdfscan.pdf“}”


当我使用内容类型调用它时,它会给出以下错误

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>400 Bad Request</title>
<h1>Bad Request</h1>
<p>The browser (or proxy) sent a request that this server could not understand.</p>

400错误请求
错误的请求
浏览器(或代理)发送了此服务器无法理解的请求


如果我在没有内容类型的情况下调用它,它会进入else,因为我得到了
request\u json=None
,对于else中的url,它会给出正确的结果


这是我有生以来第一次使用云函数,请帮助我使用request作为参数,将POST数据解析为json(或任何你想要的)

使用
--data'{“url”发出请求:http://www.africau.edu/images/defaultsample.pdf“}'-H”内容类型:application/json

现在我收到了这个错误
错误:无法处理请求
您是否将
请求
放入requirements.txt中?问题解决了。新问题
TypeError:“Request”对象不可编辑
我在
Request\u json=Request.get\u json()
@irumzahra使用
而不是
-d'{“url”:http://dl.a9t9.com/ocrbenchmark/pdfscan.pdf“}”
