javascript - 如何嵌套表单数据

Question

我想要以下 json 示例:

{
    attachments: {
        file: [
            { name: 'pic1.jpg' },
            { name: 'pic2.png' }
        ], 
        username: 'Test',
        age: 1
    }
}

这在表单数据中可能吗？

Answer 1

好吧，我明白了。只需在数组键之前传递另一个键...例如:

fd = new FormData();
const files = [{...}, {...}, ...]
files.map(file => {
    fd.append("attachments[] file[]", file.name)    
});
fd.append("attachments[] name", 'Test')
fd.append("attachments[] age", 1)
