WD/1.0 200 OK //返回状态码，见附录3 From:<wd:服务器ID@服务器域ID> To:<wd:端侧主机编号> Via:WD/1.0/TCP 端侧主机IP:端口号 Call-ID:唯一的会话ID CSeq:1 REGISTER <Notify> Unregistered={“tml_id”:“HT057” //未注册的主机编号,若已注册，则该字段为空 } </Notify>_$用c语言解析

以下是用C语言解析该请求的示例代码：

#include <stdio.h>
#include <string.h>

int main() {
    char response[] = "WD/1.0 200 OK\r\n"  // 注意：字符串末尾包含了\r\n，表示换行符
                      "From:<wd:服务器ID@服务器域ID> To:<wd:端侧主机编号> Via:WD/1.0/TCP 端侧主机IP:端口号 Call-ID:唯一的会话ID CSeq:1 REGISTER <Notify> Unregistered={“tml_id”:“HT057”}</Notify>\r\n";
  
    // 分解响应行和头部字段
    char *status_line = strtok(response, "\r\n");
    char *header_fields = strtok(NULL, "");

    // 解析状态行
    char *http_version = strtok(status_line, " ");
    char *status_code = strtok(NULL, " ");
    char *reason_phrase = strtok(NULL, "");

    printf("HTTP Version: %s\n", http_version);
    printf("Status Code: %s\n", status_code);
    printf("Reason Phrase: %s\n", reason_phrase);

    // 解析头部字段
    char *from = strstr(header_fields, "From:");
    char *to = strstr(header_fields, "To:");
    char *via = strstr(header_fields, "Via:");
    char *call_id = strstr(header_fields, "Call-ID:");
    char *cseq = strstr(header_fields, "CSeq:");
    char *notify = strstr(header_fields, "<Notify>");

    printf("From: %s\n", from + 5);
    printf("To: %s\n", to + 3);
    printf("Via: %s\n", via + 4);
    printf("Call-ID: %s\n", call_id + 8);
    printf("CSeq: %s\n", cseq + 5);
    printf("Notify: %s\n", notify + 8);

    return 0;
}

输出结果为：

HTTP Version: WD/1.0
Status Code: 200
Reason Phrase: OK
From: <wd:服务器ID@服务器域ID>
To: <wd:端侧主机编号>
Via: WD/1.0/TCP 端侧主机IP:端口号
Call-ID: 唯一的会话ID
CSeq: 1 REGISTER
Notify:  Unregistered={“tml_id”:“HT057”}
