Question

我正在运行一个flask restful API（用于天气预报），flask_rest.py和一个Web应用程序以使用名为main.py的API。我正在尝试在名为sample.html的HTML文件中使用AJAX显示输出。但是由于某种原因，结果不会动态显示。感谢您的帮助

flask_rest.py

df = df.groupby(['year','production_companies'])[['revenue']].max()
idx = df['revenue'].max(level=0).sort_values().index
i = pd.CategoricalIndex(df.index.get_level_values(0), ordered=True, categories=idx)
df.index = [i, df.index.get_level_values(1)]
df = df.sort_values(['year','revenue'], ascending=False)

main.py

                                   revenue
year production_companies

帮助!!!

Answer 1

您需要将type:'GET'更改为type:'POST'。

此外，<div>标签需要结束标签

所以改变这个：

 <div id="result"/>

对此：

<div id="result"></div>

如果您仍然遇到麻烦，请告诉我。

如何在flask restful中从AJAX GET调用接收值？
