nginx glob文件匹配

基础结构
typedef struct {
    size_t                       n;
    glob_t                       pglob;
    u_char                      *pattern;
    ngx_log_t                   *log;
    ngx_uint_t                   test;
} ngx_glob_t;

基本函数

ngx_int_t
ngx_open_glob(ngx_glob_t *gl)
{
    int  n;

    n = glob((char *) gl->pattern, GLOB_NOSORT, NULL, &gl->pglob);

    if (n == 0) {
        return NGX_OK;
    }

#ifdef GLOB_NOMATCH

    if (n == GLOB_NOMATCH && gl->test) {
        return NGX_OK;
    }

#endif

    return NGX_ERROR;
}


ngx_int_t
ngx_read_glob(ngx_glob_t *gl, ngx_str_t *name)
{
    size_t  count;

#ifdef GLOB_NOMATCH
    count = (size_t) gl->pglob.gl_pathc;
#else
    count = (size_t) gl->pglob.gl_matchc;
#endif

    if (gl->n < count) {

        name->len = (size_t) ngx_strlen(gl->pglob.gl_pathv[gl->n]);
        name->data = (u_char *) gl->pglob.gl_pathv[gl->n];
        gl->n++;

        return NGX_OK;
    }

    return NGX_DONE;
}


void
ngx_close_glob(ngx_glob_t *gl)
{
    globfree(&gl->pglob);
}

使用方式：
  gl.pattern = file.data;
    gl.log = cf->log;
    gl.test = 1;

    //打开glob
    if (ngx_open_glob(&gl) != NGX_OK) {
        ngx_conf_log_error(NGX_LOG_EMERG, cf, ngx_errno,
                           ngx_open_glob_n " \"%s\" failed", file.data);
        return NGX_CONF_ERROR;
    }

    rv = NGX_CONF_OK;

    for ( ;; ) {
        n = ngx_read_glob(&gl, &name); //读取glob

        if (n != NGX_OK) {
            break;
        }

        file.len = name.len++;
        file.data = ngx_pstrdup(cf->pool, &name);

        ngx_log_debug1(NGX_LOG_DEBUG_CORE, cf->log, 0, "include %s", file.data);

        rv = ngx_conf_parse(cf, &file);//解析glob

        if (rv != NGX_CONF_OK) {
            break;
        }
    }

    ngx_close_glob(&gl); //关闭glob
