ImageHost

PHP 循环图床，使用相对路径，可以在config.php中修改参数（最大云端文件数、支持的文件类型）

PHP部署

环境要求

1. PHP环境
2. Apache
3. 具有同目录文件"files"下的读写权限

PHP部署步骤

1. 部署PHP运行环境。可以使用PhpStudy或其他环境包一键部署。
2. 下载并拷贝phpUpload文件夹到到www目录下，运行服务即可

Web测试

1. 浏览器：http://yourip:yourport/phpUpload/upload.html

http api

1. 使用Post请求的form表单，url为http://yourip:yourport/phpUpload/upload.php
2. 对于的下载链接样式为：http://yourip:yourport/phpUpload/files/xxxxxxxxxx.png
3. 上传成功后的相应消息为:

{
  "status": "success",
  "message": "文件上传成功",
  "file_path": "files/68e8efcb8dbf4.png"
}
