3.总结
上传文件时，要使用 FormData() 构造函数，将上传的文件及参数封装在FormData()中，同时浏览器会自动识别并添加请求头 “Content-Type: multipart/form-data”，且参数依然像是表单提交时的那种键值对儿，此外 FormData() 构造函数 new 时可以直接传入 form 表单的 dom 节点。注意使用post请求，后端接收的时候可以使用requestParam，也可以不使用。
Content-Type: multipart/form-data，这种类型是后来追加的。为什么要新增一个类型，而不使用旧有的
application/x-www-form-urlencoded
：因为旧有类型不适合用于传输大型二进制数据或者包含非ASCII字符的数据。平常我们使用这个类型都是把表单数据使用url编码后传送给后端，二进制文件当然没办法一起编码进去了。所以
multipart/form-data
就诞生了，专门用于有效的传输文件。
