解决方法
data: client-body-buffer-size: 256k proxy-body-size: 25m
另外，并不推荐将这两个值设置过大，因为这样的话会导致页面加载缓慢，浪费流量，用户体验不好，应该考虑将图片压缩处理
- client_body_buffer_size 设置客户端请求体的缓冲区大小。如果请求体大于缓冲区，整个请求体或一部分就会被写入一个临时文件。默认缓冲区大小等于两个内存页，在x86,x86-64等32位平台上是8K,64位平台上通常为16K
- client_body_max_size 设置客户端请求体的最大允许大小（在“Content-Length”请求头中指定的大小），如果请求中的大小超过配置的值（即client_max_body_size），就会返回413（请求实体太大）错误码给客户端。需要注意的是，浏览器无法正确显示此错误。将大小设置为0将禁用检查客户端请求体大小
