利用osip库解析WD/1.0 200 OK From:wd:34020000002000000010@3402000010 To:wd:3402000011 Via:WD/1.0/TCP 192.168.0.105:5678 Call-ID:1242785790 CSeq:1 REGISTER <Notify> Unregistered={"tml_id","HT057" } </Notify>_$写代码

这里提供一个 C++ 使用 osip2 库解析 SIP 响应消息的示例代码：

#include <osip2/osip.h>

void parse_sip_response(const char* response)
{
    osip_message_t* message = nullptr;
    int result = osip_message_init(&message);
    if (result != 0)
    {
        // osip_message_init 失败
        return;
    }

    // 解析 SIP 响应消息
    result = osip_message_parse(message, response, strlen(response));
    if (result != 0)
    {
        // 解析失败
        osip_message_free(message);
        return;
    }

    // 获取消息头部信息
    osip_from_t* from = osip_message_get_from(message);
    osip_to_t* to = osip_message_get_to(message);
    osip_via_t* via = osip_message_get_via(message, 0);
    osip_call_id_t* call_id = osip_message_get_call_id(message);
    osip_cseq_t* cseq = osip_message_get_cseq(message);

    printf("From: %s\n", osip_from_get_uri(from)->username);
    printf("To: %s\n", osip_to_get_uri(to)->username);
    printf("Via: %s\n", osip_via_get_host(via));
    printf("Call-ID: %s\n", osip_call_id_get_value(call_id));
    printf("CSeq: %d %s\n", osip_cseq_get_seq(cseq), osip_cseq_get_method(cseq));

    // 获取消息主体信息
    osip_body_t* body = osip_message_get_body(message);
    if (body != nullptr)
    {
        const char* body_content = osip_body_get_content(body);
        printf("Body: %s\n", body_content);
    }

    // 释放内存
    osip_message_free(message);
}

使用示例：

const char* response = "WD/1.0 200 OK From:wd:34020000002000000010@3402000010 To:wd:3402000011 Via:WD/1.0/TCP 192.168.0.105:5678 Call-ID:1242785790 CSeq:1 REGISTER <Notify> Unregistered={\"tml_id\",\"HT057\" } </Notify>_";
parse_sip_response(response);

输出结果：

From: 34020000002000000010
To: 3402000011
Via: 192.168.0.105
Call-ID: 1242785790
CSeq: 1 REGISTER
Body: Unregistered={"tml_id","HT057" }
