Question

我想将数据从JS发送到Python。对于这项工作，我使用这个脚本：

function get_data(table, values,  name, keyword_column) {
            alert(table)
            alert("sending data")
            $.ajax({
                    type: "POST",
                    url: "/data",
                    data: {
                        keyword: name,
                        table: table,
                        columns: JSON.stringify(values),
                        keyword_column: keyword_column
                    },
                    success: function(data)
                    {
                       return data;
                    },
                    error: function(xhr, ajaxOptions, thrownError){
                        alert(xhr.responseText);
                    }
                 });
            //return false; // avoid actual submit
        }

上述功能的示例输入：

get_data('string',['item1','item2','item3'], 'string', 'string');

和Python：

@app.route("/data", methods=['POST', 'GET'])
def get_data():
    print('im here')
    print(str(request.form))
    table = request.form['table']
    keyword = request.form['keyword']
    columns = request.form['columns']
    keyword_column = request.form['keyword_column']
    print(table)

然而，当这样做时，我收到以下错误：
回溯（最近一次调用最后一次）：

  File "C:\Users\""\Anaconda\lib\site-packages\flask\app.py", line 1982, in wsgi_app
    response = self.full_dispatch_request()
  File "C:\Users\""\Anaconda\lib\site-packages\flask\app.py", line 1615, in full_dispatch_request
    return self.finalize_request(rv)
  File "C:\Users\""\Anaconda\lib\site-packages\flask\app.py", line 1630, in finalize_request
    response = self.make_response(rv)
  File "C:\Users\""\Anaconda\lib\site-packages\flask\app.py", line 1740, in make_response
    rv = self.response_class.force_type(rv, request.environ)
  File "C:\Users\""\Anaconda\lib\site-packages\werkzeug\wrappers.py", line 885, in force_type
    response = BaseResponse(*_run_wsgi_app(response, environ))
  File "C:\Users\""\Anaconda\lib\site-packages\werkzeug\test.py", line 884, in run_wsgi_app
    app_rv = app(environ, start_response)
TypeError: 'list' object is not callable

正如你所看到我打印了请求对象，这似乎是oke：

ImmutableMultiDict([('keyword', 'S-t'), ('table', 'gene'), ('columns', '["gene_id","name","aliases","location","description"]'), ('keyword_column', 'name')])

似乎JSON.stringify做了它的工作，但是Flask仍然会出错。
