Detailed explanation of django's example of obtaining ajax post complex object

This article mainly introduces the implementation method of django to obtain ajax post complex objects. Friends who need it can refer to it. I hope it can help everyone better master and use django to obtain ajax post complex object knowledge.

1. The post object in django's request is empty (that is, the post object transmitted by the front-end ajax cannot be obtained)

1. Comment out django.middleware.csrf.CsrfViewMiddleware in django's setting That’s it.

2, or add {% csrf %} in from, add syntax sugar to the method accepted by the background: @csrf_exempt, pay attention to add the reference module

3. If the above operation still does not work, remove the action attribute in the form tag (this is only for ajax processing, not form submission)

2. For complex ajax objects, such as [{"id": "001","name":"Xiao Ming"},{"id":"002","name":"Xiaojun"}]., the background post processing

must convert this kind of object Pass it to the backend in json format, and the backend will deserialize it. (Do not use other serialization formats of ajax. After deep serialization, Django background parsing is more difficult)

ContentType does not need to specify utf-8, otherwise post parsing error ( Commented out, no need to leave them)

For csrf and the principle of post object parsing in django request, we will add it later.
