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()
