将对象数组存储到会话Python

Question

我想在POST请求中将对象数组存储到Session我收到以下错误：

预期字符串，dict发现

def POST(self):
    deviceArr1=[{"id":"01","name":"abc"},{"id":"02","name":"abcd"}]
    for device in deviceArr1:
        cherrypy.session['deviceArr'].append(device)
    return cherrypy.session['deviceArr']

另外，我想检查是否存在重复的对象。

Answer 1

您可以在for：

中尝试此代码

try:
    cherrypy.session['deviceArr'].append(device)
except:
    cherrypy.session['deviceArr'] = [device]
