Question

我有一个需要转换的对象。我正在尝试将对象转换为FormData以上传文件

对象：

obj{
  a:
  { 
    a1: 'test1',
    a2: 'test2'
  }
  b:
  {
    b1: 'test3',
    c1: 'test4',
  }
}

转换为：

{
  obj[a][a1]: test1,
  obj[a][a2]: test2,
  obj[b]: binarydata // I want to convet this to binary data 
}

我现在无法使用的内容：

const formData = new FormData()
Object.keys(object).forEach(key => formData.append(key, object[key]));

我不是要展平数组。我正在尝试将其转换为

之类的对象

obj[key1][key2][..]: value

尝试使用Object.entries()。例如...

// If this is the object you want to convert to FormData...
const item = {
    description: 'First item',
    price: 13,
    photo: File
};

const formData = new FormData();

Object.entries(item).forEach(([key, value]) => {
    formData.append(key, value);
});

// At this point, you can then pass formData to your handler method
