我想创建一个带有关键字和类别的可视搜索界面，以便进行某些搜索。显然，它需要前端和后端数据交互。因此，在权衡了一些工具之后，我选择了 Vue 和 axios 在前端和 django视图中实现数据交互< / strong>在前端。
在index.html页面中，我这样定义了axios。
var param = new URLSearchParams();
param.append('searchKey',this.searchKey);
param.append('category',this.selected);
axios.post("{% url 'main:getCommodityInfo'%}",
param,
{headers:{'X-CSRFToken': this.getCookie('csrftoken')}},)
.then(response=>{
console.log(response);
})
.catch(error=>{
console.log(error);
alert("connection has error")
})
searchKey 和类别。然后，将数据发布到我的后端django视图中。
def getCommodityInfo(request):
if request.method=="POST":
# To get the POST paramaters
searchKey = request.POST.get('searchKey')
category = request.POST.get('category')
# unique ID for each record for DB
uniqueId = str(uuid4())
print("Enter the view! ",searchKey,category)
# set setting
settings = {
'unique_id': uniqueId,
'USER_AGENT': 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)'
}
# task Id to indentify each spider task
task = scrapyd.schedule('JDSpider', 'getCommodityInfo',
settings=settings, searchKey=searchKey, category=category)
print("It seems everything is running well? ")
print(task,uniqueId)
print("-"*100)
return JsonResponse({'taskId': task, 'uniqueId': uniqueId, 'status': 'started'},safe=False)
好吧，该视图可能会自动获取POST参数。 但是当我试图将状态json从视图返回到axios函数时，会发生错误。

我尝试调试过程，但是代码逻辑太复杂了，难以理解。 我只能发现执行时发生的错误
return JsonResponse({'taskId': task, 'uniqueId': uniqueId, 'status': 'started'},safe=False)
我正在网上搜索很长时间。但是没用。请帮助或尝试提供一些实现方法的建议。谢谢。
我已经环顾四周，显然我在下面有了选择。
<form action="{%url 'main:getCommodityInfo'%}" method="POST">
在我测试之后，使用表单可以从django视图中获取json。但是我不想在我的项目中使用它来代替axios。
