1、Form

建立一个form.asp，并保存到项目/web/目录下，内容如下：

<html>
<!-Copyright(c) Go Ahead software Inc.,2012-2012.AllRights Reserved.->
<head>
<title>Goahead Form Test</title>
<link rel="stylesheet" href="style/normal_ws.css"type="text/css">

</head>

<body>
<h1>Goahead Form Test1</h1>
<form action=/goform/formTest method=POST>

<table>

</form>

</body>
</html>

在 goahead 中增加如下内容：

websFormDefine(T("formTest"),formtest); // 注册

static voidformtest(webs_t wp, char_t *path, char_t*query) // 原型
{
char_t *name, *addr;
name = websGetVar(wp, T("name"), T(""));
addr = websGetVar(wp, T("addr"), T(""));
websHeader(wp);
websWrite(wp,T("<body><h2>Name:%s, Addr: %s</h2>\n"),name,addr);
websFooter(wp);
websDone(wp, 200);
}

2、ASP
建立一个asp.asp，并保存到项目/web/目录下，内容如下：

<divid="view">
<h4>串口状态</h4>
<table id="viewTab"class="viewTab" cellspacing="0"cellpadding="0">
  <tr>
   <thwidth="">串口</th>
   <thwidth="">线路协议</th>
   <thwidth="">波特率(bps)</th>
   <thwidth="">数据位</th>
   <thwidth="">起始位</th>
   <thwidth="">停止位</th>
   <thwidth="">奇偶校验</th>
   <thwidth="">流控</th>
  </tr>
  <%MakePortAttributeList("1", "Test", "Lanj"); %>
</table>
</div>

在 goahead中增加如下内容：

websAspDefine(T("MakePortAttributeList"),getPortAttrib); // 注册

typedef struct PortAttributeList{
char_t *port;
char_t *agreement;
char_t *bandrate;
char_t *figure;
char_t *outset;
char_t *termination;
char_t *parityCheck;
char_t *flowControl;
}STPortAttributeList;

static voidgetPortA(webs_t wp, STPortAttributeList *PortAttributeList)
{
PortAttributeList[0].port="1";
PortAttributeList[0].agreement="RS232";
PortAttributeList[0].bandrate="1200";
PortAttributeList[0].figure="8";
PortAttributeList[0].outset="1";
PortAttributeList[0].termination="1";
PortAttributeList[0].parityCheck="ODD";
PortAttributeList[0].flowControl="Hardware";
PortAttributeList[1].port="2";
PortAttributeList[1].agreement="RS485";
PortAttributeList[1].bandrate="9600";
PortAttributeList[1].figure="8";
PortAttributeList[1].outset="1";
PortAttributeList[1].termination="1";
PortAttributeList[1].parityCheck="EVEN";
PortAttributeList[1].flowControl="NO";
}

static int getPortAttrib(int eid, webs_t wp, int argc, char_t**argv) // 原型
{
int i=0;
int SerialNum = 2;
STPortAttributeList PortAttributeList[SerialNum];
printf("Parameter = %d\n",argc);

while(i <argc)
{
printf("Parameter%d = %s\n",i,*(argv+i));
i++;
}
i = 0;

getPortA(wp,PortAttributeList);
while(i<SerialNum)
{
  websWrite(wp,T("<tr>"));
  websWrite(wp,T("<td>%s</td>"),PortAttributeList[i].port);
  websWrite(wp,T("<td>%s</td>"),PortAttributeList[i].agreement);
  websWrite(wp,T("<td>%s</td>"),PortAttributeList[i].bandrate);
  websWrite(wp,T("<td>%s</td>"),PortAttributeList[i].figure);
  websWrite(wp,T("<td>%s</td>"),PortAttributeList[i].outset);
  websWrite(wp,T("<td>%s</td>"),PortAttributeList[i].termination);
  websWrite(wp,T("<td>%s</td>"),PortAttributeList[i].parityCheck);
  websWrite(wp,T("<td>%s</td>"),PortAttributeList[i].flowControl);
  websWrite(wp,T("</tr>"));
  i++;
}
return 0;
}

3、CGI

建立一个cgi.asp，并保存到项目/web/目录下，内容如下：

<formaction="/cgi-bin/cgitest">

</form>

新建 cgitest.c，程序如下：

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
char *data;
int i;
long m=0,n=0;
printf("Content-type: text/html\n\n");
printf("<TITLE>Multi S</TITLE>");
printf("<H3>MultiS</H3>");
data = getenv("QUERY_STRING");

printf("<P>%s\n",data);
if(data == NULL)
  printf("<P>ERROR! DATA NO INPUT");
elseif(sscanf(data,"m=%ld&n=%ld",&m,&n)!=2)
  printf("<P>ERROR! DATA GET ERROR");
else
  printf("<P>%ld * %ld = %ld.", m, n, m*n);

return 0;
}

编译后把可执行文档 cgitest 保存到 /cgi-bin/ 目录。
