How to escape characters in SIL?

[Chris Kast]

I'm building a SIL script that uses the httpPost method (I'm sending a POST to the Slack API). In my post, I'm sending an embedded link and the way Slack formats this is:

<http://www.google.com|This is a link to Google>

Where "This is a link to Google" is the hyperlink. So my full script would look something like this:

string url = "https://slack.com/api/chat.postMessage";
string [] headers = "Accept|text/plain";
string [] params = "token|my_token|channel|ckast-private|text|<http://www.google.com|This is a link to Google>";
httpPost(url, headers, params);

The problem is when sending a request via httpPost, it separates the key:values with "pipes" (|). So when it reads the above, it thinks the "pipe" is starting a new key:value pair. Is there a way to escape this out in the SIL script? I tried using double backslashes but that didn't work. Here's the error I'm getting:

Running sil script failed.

Ok, now this code should work:

string url = "https://slack.com/api/chat.postMessage";
string [] headers = "Accept|text/plain";
string link = "<http://www.google.com|This is a link to Google>";
string[] params = {"token","my_token","channel","ckast-private","text", link};
httpPost(url, headers, params);

Best regards,

Thanks, Alex. Using your exact example above, all this does is post "final" which makes sense since "final" is encapsulated in the quotes. I'm assuming I need to concatenate? I tried doing this: string [] params = "token|my_token|channel|ckast-private|text|" + final; But that produces my original error. What's the appropriate way to concatenate inside of an array? Thanks again!

Sorry Chris, my bad, i've edited the code block.

Perfect! Thanks, Alex. This worked great.

Hello Chris,

I've used a script like this and it works:

string [] headers = "Accept|text/plain|Accept-Language|ro_RO";
string [] params = "param1|value1|param2|value2";
headers += "custom-url";
headers += "http://www.google.com/reallyworks";
string google = "http://www.google.com/search?q=test";
httpPost(google, headers, params);

Have a nice day,
Alex

Sorry...maybe I should have been more clear. The link to Google is a actually a part of the text that's being sent as a parameter in the payload (Google is just an example...I can be any URL). I've updated my original question with the code I have now. Hopefully that's more clear.
