How to escape characters in SIL?

Chris Kast May 14, 2015

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!

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.
