python - “coroutine”对象没有属性 get || pyppeteer

Question

在Python中，使用pyppeteer，我打开一个网页并在其控制台中运行JS脚本并尝试捕获结果在变量中，但我收到以下错误。

Traceback (most recent call last):
  File "/home/ndaruto/anaconda3/lib/python3.7/site-packages/django/core/handlers/exception.py", line 34, in inner
    response = get_response(request)
  File "/home/naruto/anaconda3/lib/python3.7/site-packages/django/utils/deprecation.py", line 96, in __call__
    response = self.process_response(request, response)
  File "/home/naruto/anaconda3/lib/python3.7/site-packages/django/middleware/clickjacking.py", line 26, in process_response
    if response.get('X-Frame-Options') is not None:
AttributeError: 'coroutine' object has no attribute 'get'
/home/naruto/anaconda3/lib/python3.7/pathlib.py:704: RuntimeWarning: coroutine 'hmm' was never awaited


return self._str
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

下面是 python 代码:-

async def hmm(request):
browser = await launch()
page = await browser.newPage()
await page.goto('http://jobs.chegg.com')
ans = await page.evaluate('''() => {
    var script = document.createElement('script');
    script.type = 'text/javascript';
    script.src = 'https://cdnjs.cloudflare.com/ajax/libs/axe-core/3.1.2/axe.min.js';
    document.head.appendChild(script);
    setTimeout(function(){
    axe.run(document, {
        runOnly: {
        type: "tag",
        values: ["wcag2a", "wcag2aa", "best-practice"]
        },
        "rules": {
        "skip-link": { enabled: false }
        }
    }, function(err, results) {
        if (err) throw err;
        console.log(results);
    });
    }, 1000);
}''')
print("ANS IS", ans)
return 1

有人可以建议如何解决这个问题吗？

AttributeError:“coroutine”对象没有属性“get”
/home/naruto/anaconda3/lib/python3.7/pathlib.py:704:RuntimeWarning:从未等待协程“hmm”
这意味着你打电话嗯(请求).get()
相反
r = 等待嗯(请求)
r.get()
在你的代码中围绕这个函数的某个地方
