Question

CF2021 uses CFHTTP to pass parameters to the LINE group via IFTTT

Hi ! Dear experts

I wrote a simple program to send LINE notifications to customer groups via IFTTT.

Just pass three simple URL parameters, which are as follows:

 

<CFHTTP Url=https://maker.ifttt.com/trigger/mic0121_line/with/key/boYiM....   Method="get" Charset="utf-8" ResolveUrl="Yes">

  <CFHTTPPARAM Type=“url” Name=“value1” Value='test_url_01'>

  <CFHTTPPARAM Type="url" Name="value2" Value='測試參數 2' >

  <CFHTTPPARAM Type="url" Name="value3" Value='測試參數3' >

</CFHTTP>

 

mic0121_line is the LINE customer group code defined in IFTTT, value1, value2, value3 are 3 URL parameters, some of which are Chinese Traditional characters (big5 code).

 

These codes are OK on the CF2021 Update5 test on ColdFusion Fiddle.

But why can't I send it properly when executed on my installed CF2021 Update5 computer.

 

Are there any settings that need to be changed in CF2021 Adminstrator?

Help us help you: what's the error or result you're getting?

 

You've said only that you "can't send it properly".  What tells you that? What's in the cfhttp.filecontent, or indeed in a dump of the cfhttp scope?

Thank you for your help, output cfhttp variable observation filecontent as shown in the figure, there is a "Connection Failure" error; But on Fiddle execution was successful, and appears "Congratulations ! You've fired the mic0121_line event"。

Ok, thanks for that. And based on it, I'd say that a likely difference between your machine and the cfiddle is that you may not have updated that Java that underlies your cf. For more on how that's a common cause of such cfhttp failures, as well as how to go about resolving the matter (updating the Java cf uses), see my blog post on the cf portal:

 

https://coldfusion.adobe.com/2019/06/error-calling-cf-via-https-solved-updating-jvm/

 

And as for how to detect the version of Java you're running, I have a post on that as well:

 

https://www.carehart.org/blog/2021/4/5/Confirming-ColdFusions-Java-version-via-CFML-code

 

And if you have trouble afrtet updating the jvm, I have a post on that as well:

Let us know how things go.

Open /cfusion/bin/jvm.config in a text editor. Ensure that java.args contains the following flag:

 

-Dfile.encoding=UTF-8

 

If you add the flag, you will have to restart ColdFusion.

Thank you for your reply !

I followed your suggestion to set up and restart and still can't send LINE notifications. But executing on my another CF2016 computer and ColdFusion Fiddle CF2021 Update5 are OK.

Oh, I have just seen something odd. The code sample you posted above has curly quotes:

“url” Name=“value1”

Replace them with normal double quotes or with single quotes:

"url" Name="value1"
'url' Name='value1'
