python - 烧瓶 api 没有返回 xml

Question

我不能让我的 Flask API 返回 XML。

我在错误日志中没有收到任何错误，但这是来自服务器日志：

2020-06-10 21:14:01 [Errno 2] No such file or directory: '<bound method Response.json of <Response [200]>>'

2020-06-10 21:14:02 spawned 2 offload threads for uWSGI worker 1

从 pythonanywhere 我得到这个消息：

                If this is your PythonAnywhere-hosted site, and you just reloaded

                If there&#39;s nothing in the logs, and you&#39;re sure your site is OK,
                then it might be a problem on our side. Drop us a line at

        </div>

        <p>
            Error code: 502-backend

这是我的代码：

r = requests.request("GET", url, headers=headers)

# get the xml from a json string

if r.status_code == 200:
    js_data = str(r.json)
    xml_data = readfromjson(js_data)
    return json2xml.Json2xml(xml_data).to_xml()

我可以返回 js_data 没问题
