data:{id:1, type:encodeURI(encodeURI(‘商品'))}

2. Decode the obtained string in the background action

Method 2: ajax configure the contentType attribute, add charset=UTF-8

Add the following parameters to the ajax method

contentType: "application/x-www-form-urlencoded; charset=UTF-8" It's similar when using other js frameworks or xhr. Just set the contentType in the header.
