C++-Mongoose(3)-http-server-https-restful

news 2025/7/8 6:29:14

1.url 结构

2.http和 http-restful区别在于对于mg_tls_opts的赋值

2.1 http和https 区分

a) port地址

static const char *s_http_addr = "http://0.0.0.0:8000"; // HTTP port

static const char *s_https_addr = "https://0.0.0.0:8443"; // HTTPS port

b)https时对mg_tls_opts赋值

 struct mg_tls_opts opts = {
#ifdef TLS_TWOWAY.ca = mg_str(s_tls_ca),
#endif.cert = mg_str(s_tls_cert),.key = mg_str(s_tls_key)};mg_tls_init(c, &opts);}

3个重要变量:
static const char* s_tls_ca ;
static const char* s_tls_cert；
static const char* s_tls_key;

#ifdef TLS_TWOWAY
static const char* s_tls_ca =
