开发步骤：
定义配置项static ngx_command_t ngx_http_mytest_commands[] = { { ngx_string("mytest"), NGX_HTTP_MAIN_CONF | NGX_HTTP_SRV_CONF | NGX_HTTP_LOC_CONF | NGX_HTTP_LMT_CONF | NGX_CONF_NOARGS, ngx_http_mytest, NGX_HTTP_LOC_CONF_OFFSET, 0, NULL }, ngx_null_command};
实现ngx_http_mytest函数
static char* ngx_http_mytest(ngx_conf_t *cf, ngx_command_t *cmd, void *conf) { ngx_http_core_loc_conf_t *clcf;clcf = ngx_http_conf_get_module_loc_conf(cf, ngx_http_core_module);clcf->handler = ngx_http_mytest_handler;return NGX_CONF_OK;}
定义ngx_http_module_t的8个回调函数
static ngx_http_module_t ngx_http_mytest_module_ctx = { NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL };
定义mytest模块
ngx_module_t ngx_http_mytest_module = { NGX_MODULE_V1, &ngx_http_mytest_module_ctx, ngx_http_mytest_commands, NGX_HTTP_MODULE, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NGX_MODULE_V1_PADDING };
定义处理函数
static ngx_int_t ngx_http_mytest_handler(ngx_http_request_t *r) { if (!(r->method & (NGX_HTTP_GET | NGX_HTTP_HEAD))) { return NGX_HTTP_NOT_ALLOWED; }// Discard request body ngx_int_t rc = ngx_http_discard_request_body(r); if (rc != NGX_OK) { return rc; } // Send response header ngx_str_t type = ngx_string("text/plain"); ngx_str_t response = ngx_string("Hello World!"); r->headers_out.status = NGX_HTTP_OK; r->headers_out.content_length_n = response.len; r->headers_out.content_type = type; rc = ngx_http_send_header(r); if (rc == NGX_ERROR || rc > NGX_OK || r->header_only) { return rc; } // Send response body ngx_buf_t *b; b = ngx_create_temp_buf(r->pool, response.len); if (b == NULL) { return NGX_HTTP_INTERNAL_SERVER_ERROR; } ngx_memcpy(b->pos, response.data, response.len); b->last = b->pos + response.len; b->last_buf = 1; ngx_chain_t out; out.buf = b; out.next = NULL; return ngx_http_output_filter(r, &out); }
开发自定义模块
自定义模块：mytest
mytest/├── config└── ngx_http_mytest_module.c
添加config文件添加ngx_http_mytest_modul.c文件修改nginx.conf文件
