c++ - Luci 无法启动请求的 CGI 程序：/www/cgi-bin/sample.cgi：执行错误

Question

我试图uhttpd server在安装时运行Cgi-Cpp 程序OpenWRT。Cgi 文件是/www/cgi-bin/sample.cgi并且也具有执行权限。我正在尝试使用 HTML 文件访问此 Cgi。这是我的sample.cgi文件：

#include <iostream>
#include <vector>  
#include <string>  
#include <stdio.h>  
#include <stdlib.h> 

#include <cgicc/CgiDefs.h> 
#include <cgicc/Cgicc.h> 
#include <cgicc/HTTPHTMLHeader.h> 
#include <cgicc/HTMLClasses.h>  

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;
}

单击 HTML 中的提交按钮时出现错误：

unable to launch the requested CGI program: /www/cgi-bin/sample.cgi: Exec error

我错过了什么？所有权限都设置在那里。有什么建议么？

确保您正在正确构建程序。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。您应该在那里看到您的 sample.cpp 文件。如果它不在那里，请将其移到那里。如果您不再有 sample.cpp 文件，请使用您最初发布的代码创建一个文本文件。您可以使用 nano 之类的文本编辑器来完成此操作。

nano sample.cpp

键入或粘贴到您的源文件中。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

“-o”是字母“o”，而不是数字“0”。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“sample.cgi”。

确保“sample.cgi”是可执行的。如果不是，则使其可执行

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，那么服务器也不能这样做。然后输入

"./sample.cgi".

执行应用程序后，您应该会在终端窗口中看到从应用程序发送的 html。

如果您需要进一步的帮助，请告诉我们。

如果您尝试制作表单，则使用 shell 脚本，然后使用 c++。在这里，我向您展示了我如何创建一个文件，在该文件中路由器可以设置为任何模式，如 dhcp、pppoe 或静态。

#!/bin/sh

echo "Content-type: text/html"
echo ""
echo '<html>'
echo '<head>'
echo '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">'
