Example: HTTP Actions and Proxy Servers

[Adam]

All three of our HTTP actions have the option of using a table that contains the user's proxy information. The function below will accept the user's proxy information obtained from Input objects and return a table of these values.

This is the function code:

-- This function will test the variables that were provided and then 
-- populate the table with valid data
function GenerateProxyTable(UserName,Password,ServerAddress,ServerPort)
	
	-- This creates the default table
	ProxyTable = {PUserName = "",PPassword = "",PServerAddress = "",PServerPort = 0};
	
	-- Make sure that there is data
	if UserName ~= "" then
		-- Add the value to the table
		ProxyTable.PUserName = UserName;
	end

	-- Make sure that there is data
	if Password ~= "" then
		-- Add the value to the table
		ProxyTable.PPassword = Password;
	end

	-- Make sure that there is data
	if ServerAddress ~= "" then
		-- Add the value to the table
		ProxyTable.PServerAddress = ServerAddress;
	end

	-- Convert the string to a number
	tempNum = String.ToNumber(ServerPort);
	-- Make sure that there is data
	if tempNum ~= 0 then
		-- Add the value to the table
		ProxyTable.PServerPort = tempNum;
	end
	
	-- Return the generated table
	return ProxyTable;

end

You would then call this function using the following code:

-- Get the values from the Input objects
Name = Input.GetText("UserName");
Pass = Input.GetText("Password");
Addr = Input.GetText("Address");
Port = Input.GetText("Port");

-- Pass these values to the GenerateProxyTable function
ProxyInfo = GenerateProxyTable(Name,Pass,Addr,Port);

-- Show a dialog that shows the saved data.
Dialog.Message("Stored Proxy Info","User Name = "..ProxyInfo.PUserName.."\nPassword = "..ProxyInfo.PPassword.."\nAddress = "..ProxyInfo.PServerAddress.."\nPort = "..ProxyInfo.PServerPort);

The table returned can now be used with any of the following functions:

• HTTP.Download()
• HTTP.Submit()
• HTTP.TestConnection()
