这是有问题的代码：

@app.route('/getAcadNews')
def getAadNews():
    headers = {
        'accept': "application/json",
        'cache-control': "no-cache",
        'Ocp-Apim-Subscription-Key': "<API KEY HERE>"
    }

    news_items = {}

    query = removeBadOrdinal(request.args.get('kws'))
    url = "https://api.cognitive.microsoft.com/bing/v5.0/news/search?"

    querystring = {"q":"\""+query+"\" and \"papers published\"","count":"10000","freshness":"Month"}
    try:
        papernews = json.loads(requests.request("GET", url, headers=headers, params=querystring).text)
    except requests.exceptions.ConnectionError:
        papernews = {}

    if "totalEstimatedMatches" in papernews:
        news_items['papers_published_news'] = papernews["totalEstimatedMatches"]
        news_items['papers_published_news_item'] = getTopNews(papernews)
    else:
        news_items['papers_published_news'] = 0
        news_items['papers_published_news_item'] = {}

    querystring = {"q":"\""+query+"\" and \"patent\"","count":"10000","freshness":"Month"}
    try:
        patentnews = json.loads(requests.request("GET", url, headers=headers, params=querystring).text)
    except requests.exceptions.ConnectionError:
        patentnews = {}
    if "totalEstimatedMatches" in patentnews:
        news_items['patent_news'] = patentnews["totalEstimatedMatches"]
        news_items['patent_news_item'] = getTopNews(patentnews)
    else:
        news_items['patent_news'] = 0
        news_items['patent_news_item'] = {}

    resp1 = (json.dumps(news_items, indent=4))
    resp = Response(response=resp1,
        status=200, \
        mimetype="application/json")
    return(resp)

这有时有效，但有时我会遇到以下错误：

如果有人可以帮我解决这个问题，那将非常有帮助。我在付费 S2 层。此问题主要发生在此函数被连续调用 3 次以上时。

不幸的是，你或我无能为力，这是微软的错。尽管您可能不喜欢这个答案，但它们限制了请求和带宽。如果您的互联网速度很慢，这可能是一个因素。
