ngx.sha1_bin ------------ **语法:** *digest = ngx.sha1_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 `SHA-1` 计算 `str` 字符串返回二进制的数据。 在安装 `Nginx` 时 这个函数需要 `SHA-1` 的支持。（这通常说明应该在安装 `Nginx` 时一起安装 `OpenSSL` 库）。 这个方法在 `v0.5.0rc6` 版本中首次引入。 [Back to TOC](#nginx-api-for-lua) > English source: **syntax:** *digest = ngx.sha1_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 SHA-1 digest of the `str` argument. This function requires SHA-1 support in the Nginx build. (This usually just means OpenSSL should be installed while building Nginx). This function was first introduced in the `v0.5.0rc6`.
