ngx.md5_bin ----------- **语法:** *digest = ngx.md5_bin(str)* **环境:** *set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua*, ngx.timer.** 通过 `MD5` 计算 `str` 字符串返回二进制的数据。 如果需要返回纯文本数据请看 [ngx.md5](ngxmd5.md) 方法。 [Back to TOC](#nginx-api-for-lua) > English source: **syntax:** *digest = ngx.md5_bin(str)* **context:** *set_by_lua*, rewrite_by_lua*, access_by_lua*, content_by_lua*, header_filter_by_lua*, body_filter_by_lua*, log_by_lua*, ngx.timer.** Returns the binary form of the MD5 digest of the `str` argument. See [ngx.md5](#ngxmd5) if the hexadecimal form of the MD5 digest is required.
