So you always get the dyn\nprotocol action on unknown parts of the URL space.\n\nThis solves that behaviour by adding a new protocols[0] that calls\nstraight through to the default protocol handler lws_callback_http_dummy(),\nand moves the dyn handler to be protocols[1].\n\nIn addition it shows how to check the url path in the dyn handler for\ncases where user code doesn't want to add the second protocol." , "diff": "diff --git a/minimal-examples/http-server/minimal-http-server-dynamic/minimal-http-server-dynamic.c b/minimal-examples/http-server/minimal-http-server-dynamic/minimal-http-server-dynamic.c\nindex 77ca694..af0b220 100644\n--- a/minimal-examples/http-server/minimal-http-server-dynamic/minimal-http-server-dynamic.c\n+++ b/minimal-examples/http-server/minimal-http-server-dynamic/minimal-http-server-dynamic.c\n@@ -49,11 +49,27 @@ callback_dynamic_http(struct lws *wsi, enum lws_callback_reasons reason,\n \tswitch (reason) {\n \tcase LWS_CALLBACK_HTTP:\n \n-\t\t/* in contains the url part after our mountpoint /dyn, if any */\n-\t\tlws_snprintf(pss-\u003epath, sizeof(pss-\u003epath), \u0022%s\u0022, (const char *)in);\n+\t\t/*\n+\t\t * If you want to know the full url path used, you can get it\n+\t\t * like this\n+\t\t *\n+\t\t * n \u003d lws_hdr_copy(wsi, buf, sizeof(buf), WSI_TOKEN_GET_URI);\n+\t\t *\n+\t\t * The base path is the first (n - strlen((const char *)in))\n+\t\t * chars in buf.\n+\t\t */\n+\n+\t\t/*\n+\t\t * In contains the url part after the place the mount was\n+\t\t * positioned at, eg, if positioned at \u0022/dyn\u0022 and given\n+\t\t * \u0022/dyn/mypath\u0022, in will contain /mypath\n+\t\t */\n+\t\tlws_snprintf(pss-\u003epath, sizeof(pss-\u003epath), \u0022%s\u0022,\n+\t\t\t\t(const char *)in);\n \n \t\tlws_get_peer_simple(wsi, (char *)buf, sizeof(buf));\n-\t\tlwsl_notice(\u0022%s: HTTP: connection %s\u005cn\u0022, __func__, (const char *)buf);\n+\t\tlwsl_notice(\u0022%s: HTTP: connection %s, path %s\u005cn\u0022, __func__,\n+\t\t\t\t(const char *)buf, pss-\u003epath);\n \n \t\t/*\n \t\t * prepare and write http headers... with regards to content-\n@@ -178,10 +194,11 @@ callback_dynamic_http(struct lws *wsi, enum lws_callback_reasons reason,\n \treturn lws_callback_http_dummy(wsi, reason, user, in, len);\n }\n \n-static const struct lws_protocols protocol \u003d\n+static const struct lws_protocols defprot \u003d\n+\t{ \u0022defprot\u0022, lws_callback_http_dummy, 0, 0 }, protocol \u003d\n \t{ \u0022http\u0022, callback_dynamic_http, sizeof(struct pss), 0 };\n \n-static const struct lws_protocols *pprotocols[] \u003d { \u0026protocol, NULL };\n+static const struct lws_protocols *pprotocols[] \u003d { \u0026defprot, \u0026protocol, NULL };\n \n /* override the default mount for /dyn in the URL space */\n \n","s":{"c":1752719382,"u": 1767}} ],"g": 2555,"chitpc": 0,"ehitpc": 0,"indexed":0 , "ab": 0, "si": 0, "db":0, "di":0, "sat":0, "lfc": "0000"}
