Question

我在vue上有这样的数据结构

data: {
   name: 'Lorem',
   status: 'Active',
   username: 'user-01',
   password: '12345'
},

然后我附加到FormData()，因为我想像这样将blob数据（图像）发送到服务器

let formData = new FormData(this.data); // my data
formData.append('photo', this.blob);

我使用axios，发送了图像但没有发送数据，当我在控制台上显示formData.entries（）时，结果是

photo, [object File]

我该如何解决？谢谢

Rembermer FormData没有将JSON数据作为参数的构造方法。

尝试一下

将数据追加到FormData（）时为null
