Question

我尝试在#!/bin/bash #### Used to set the type of script "bash" set +xe #### Used to execute the script in debug mode (set +x) and e is used to receive the input from terminal if [ x"$Link_A" == "x" ] ; then ##### condition check if x appending something is equal to x means no value in variable LinK_A echo "Link_A parameter not set, DOESNOT execute FUNCTION" ##### print this line if above condition is true else ###### if above condition is not true do below operation cp -f ~/cached-resources/www.github.com/file1/executables/JenkinsScripts/jenkins_feed.pl ./jenkins_feed.pl #####above line copy the file jenkis_feed.pl from specified directory to current dir forcefully perl jenkins_feed.pl $JENKINS_HOME/feed_bts.ini $Link_A #### execute jenkil program which take two input parameter fi安装上运行的uhttpd server上执行Cgi-Cpp程序。 Cgi文件是OpenWRT并且也具有执行权限。我试图用HTML文件访问这个Cgi。这是我的/www/cgi-bin/sample.cgi文件：

sample.cgi

单击HTML中的提交按钮时出现错误：

using namespace std;
using namespace cgicc;

int main () {
   Cgicc formData;

   cout << "Content-type:text/html\r\n\r\n";
   cout << "<html>\n";
   cout << "<head>\n";
   cout << "<title>Using GET and POST Methods</title>\n";
   cout << "</head>\n";
   cout << "<body>\n";

   form_iterator fi = formData.getElement("first_name");  

   if( !fi->isEmpty() && fi != (*formData).end()) {  
      cout << "First name: " << **fi << endl;  
   }else{
      cout << "No text entered for first name" << endl;  
   }
   cout << "</body>\n";
   cout << "</html>\n";

   return 0;
}

我错过了什么？所有权限都设置在那里。有什么建议吗？

Answer 1

如果您尝试创建表单然后使用shell脚本然后使用c ++。在这里，我向您展示我如何创建一个文件，路由器可以在任何模式下设置，如dhcp，pppoe或static。

#!/bin/sh

echo "Content-type: text/html"
echo ""
echo '<html>'
echo '<head>'
echo '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">'
echo '</head>'
echo '<br><h1><center>Welcome to Internet Service</center></h1>'

只需从html调用此文件，它将在任何浏览器中打开注意： - 授予此文件777的权限，并且不对此文件提供任何扩展名。只需通过提供名称即可保存。

Answer 2

确保正确构建程序。首先打开一个终端窗口并cd到/ www / cgi-bin。现在使用

ls -l

列出目录中的程序。你应该在那里看到你的sample.cpp文件。如果不存在，请将其移至那里。如果您不再拥有sample.cpp文件，请使用最初发布的代码创建文本文件。您可以使用像nano这样的文本编辑器来完成此操作。

nano sample.cpp

输入或粘贴源文件。然后按ctrl-x保存并退出程序。确保告诉nano保存程序而不是退出。

接下来删除现有的sample.cgi。不要删除sample.cpp。

使用此命令将源代码（sample.cpp）构建为二进制可执行文件：

g++ sample.cpp -o sample.cgi

＆＃34; -o＆＃34;是字母＆＃34; o＆＃34;而不是数字＆＃34; 0＆＃34;。如果构建引发编译错误，请修复错误并重复，直到成功构建程序。您现在将拥有一个二进制文件＆＃34; sample.cgi＆＃34;。

确保＆＃34; sample.cgi＆＃34;是可执行的。如果没有，那么使用

使其可执行

sudo chmod a+x sample.cgi

确保您可以先从命令行执行sample.cgi。如果你不能这样做，那么服务器也无法做到。然后输入

"./sample.cgi".

在执行应用程序后，您应该会在终端窗口中看到您从应用程序发送的html。
