HTTP响应出现问题 - 编程之家

如何解决HTTP响应出现问题

我的简单小型Web服务器C出现问题。我使用的URL是：

127.0.0.1:2000/eslami

，我希望看到其中写有beneslami的简单页面。下面是我的GET请求处理器例程

static char*
process_GET_request(char * URL,unsigned int *response_length){
  printf("%s(%u) called with URL = %s\n",__FUNCTION__,__LINE__,URL);
  char delimiter[2] = "/";
  char *token;
  token = strtok(URL,delimiter);

  printf("%s\n",token);
  char *response = calloc(1,1024);
  HTML_create(response,token);
  char *header = calloc(1,248 + strlen(response));
  HTTP_header_create(header);
  strcat(header,response);
  *response_length = strlen(header);
  free(response);
  return header;
}

下面是HTML_create函数

static void
HTML_create(char *response,char *token){
  strcpy(response,"<html>"
                   "<h>names</h>"
                   "<p>");
  strcat(response,token);
  strcat(response,"</p>");
  strcat(response,"</html>");
}

和HTTP_header_create

static void
HTTP_header_create(char *header){
  strcpy(header,"HTTP/1.1 200 OK\r\n");                           // Status Line
  strcat(header,set_current_date_time("date"));                         // General Headers
  strcat(header,"Connection: close\r\n");
  strcat(header,"Server: My Personal HTTP Server\r\n");           //Response Headers
  strcat(header,"Accept-Ranges: bytes\r\n");
  strcat(header,"Content-Type: text/html\r\n");                   //Entity Headers
  strcat(header,"Content-Length: \r\n");
  strcat(header,set_current_date_time("date_time"));
  strcat(header,"\r\n");
}

static char*
set_current_date_time(char *option){
  time_t t;
  time(&t);
  char *temp;
  char *day;
  int day_number;
  char *month;
  int year;
  char *current_time;
  const char delimiter[2] = " ";
  temp = ctime(&t);
  day = strtok(temp,delimiter);
  month = strtok(NULL,delimiter);
  day_number = atoi(strtok(NULL,delimiter));
  current_time = strtok(NULL,delimiter);
  year = atoi(strtok(0,delimiter));
  char *output = calloc(1,1024);
  if(strcmp(option,"date_time")){
    sprintf(output,"Last-Modified: %s,%d %s %d %s GMT\r\n",day,day_number,month,year,current_time);
    return output;
  }
  else if(strcmp(option,"date")){
    sprintf(output,"Date: %d %s %d\r\n",year);
    return output;
  }
  return NULL;
}

根据上述设置，我在浏览器上只看到一个空白页。我什至捕获了我的localhost接口，并确认我的服务器发送了如下的HTTP响应

将响应发送给客户端：

HTTP/1.1 200 OK
Last-Modified: Fri,25 Sep 2020 19:27:03 GMT
Connection: close
Server: My Personal HTTP Server
Accept-Ranges: bytes
Content-Type: text/html
Content-Length:
Date: 25 Sep 2020

<html><h>names</h><p>eslami</p></html>

有人能找出我上面的代码有什么问题吗？

谢谢
