Out of ideas with CURL vs JS vs Xojo

1

Have a weird one
I have some code I wrote in Xojo thats basically a translation of some JS code - see below

But it gave me errors for reasons I couldn’t fathom

So I used RapidApi (formerly PAW) to test the same API
When I fill out what I need it generates a call using CURL
I get the following CURL invocation

curl -X “POST” “``https://graph.facebook.com/v24.0/958069794056499/media``”
-H ‘Authorization: Bearer EAAlZAJ8PZBulkBQr8Sr8eKMBM188ZBeAxPm6GXbKoPnjqKryAMFItZBkDNKUSVJMe7AOCkCmcx98ZCowIZAW15NJqQo4UOMKgTnpnLkYWujq93yUvCeGLag3dP7PhZC41TpKo0jbYCtxd0B6XxeeIihvRnqafLPqkHZChWEwX2141ohZBLv6S6s3b6g2LzXy2ISYtAY1FeZCy8xfSXZBhNZB8mhoa5f7S1RstIWLq77evO2B1MhvYnDEJDrpmFeE1IZCXeWzkn8ZAfmTJRhMknnMxFxGWccdlZC5cxaTggXBA4F’
-H ‘Content-Type: multipart/form-data’
-F “file=@/Users/npalardy/Desktop/dF8Jup.jpg”
-F “type=image/jpeg”
-F “messaging_product=whatsapp”

and I get a result like

{“id”:“2966336126899864”}

So far YAY !

Then I have Rapid API generate it as JS


import (“https://code.jquery.com/jquery-3.6.3.min.js”) ;

var formData = new FormData();
formData.append(“file”, “@/Users/npalardy/Desktop/dF8Jup.jpg”);
formData.append(“type”, “image/jpeg”);
formData.append(“messaging_product”, “whatsapp”);

jQuery.ajax({
url: “https://graph.facebook.com/v24.0/958069794056499/media”,
type: “POST”,
headers: {
“Authorization”: “Bearer EAAlZAJ8PZBulkBQr8Sr8eKMBM188ZBeAxPm6GXbKoPnjqKryAMFItZBkDNKUSVJMe7AOCkCmcx98ZCowIZAW15NJqQo4UOMKgTnpnLkYWujq93yUvCeGLag3dP7PhZC41TpKo0jbYCtxd0B6XxeeIihvRnqafLPqkHZChWEwX2141ohZBLv6S6s3b6g2LzXy2ISYtAY1FeZCy8xfSXZBhNZB8mhoa5f7S1RstIWLq77evO2B1MhvYnDEJDrpmFeE1IZCXeWzkn8ZAfmTJRhMknnMxFxGWccdlZC5cxaTggXBA4F”,
“Content-Type”: “multipart/form-data”,
},
processData: false,
contentType: false,
data: formData,
})
.done(function(data, textStatus, jqXHR) {
console.log("HTTP Request Succeeded: " + jqXHR.status);
console.log(data);
})
.fail(function(jqXHR, textStatus, errorThrown) {
console.log(“HTTP Request Failed”);
console.log(jqXHR) ;
})
.always(function() {
/* … */
});

I test this in RunJS online
But this time I get
Promise { }
{
readyState: 1,
getResponseHeader: [Function: getResponseHeader],
getAllResponseHeaders: [Function: getAllResponseHeaders],
setRequestHeader: [Function: setRequestHeader],
overrideMimeType: [Function: overrideMimeType],
statusCode: [Function: statusCode],
abort: [Function: abort],

always: [Function: always],
catch: [Function: catch],
pipe: [Function: pipe],
then: [Function: then],
promise: [Function: promise],
progress: [Function: add],
done: [Function: add],
fail: [Function: add]
}
‘HTTP Request Failed’
{

‘}’,
responseJSON: {

}

One works
the other two dont
I cant figure out why

Anyone got ANY ideas ?

Firstly: Remove/Revoke the Access Token, it’s now compromised.

Secondly: I see a content-type mismatch in your JS. In curl you send properly a binary file (the content of.jpg file) in JS you just send a string. Likely there’s the mistake.

Lastly: CORS?

3

The tokens are temporary me so they expired before I posted :slight_smile:
And I now see what my issue is

CURL treats the @ specially

so I need to manually do what that does

4

OK I have fixed all that stuff and comparing what CURL sends vs what I now send its darned near byte for byte the same (boundary markers aside)

And damned FB still rejects it saying a parameter is missing

scratching my head

Converted my Xojo to C# and .. it works

tried changing headers in Xojo … no dice
added Aton of headers to the CURL request - it just works

Now I’m really scratching the bottom of the barrel here

5

make your own rest API and check what Xojo is doing…

6

I just had a tiny little xojo app with HandleURL in it and as far as I can tell CURL & Xojo do exactly the same

The body content is the same

the URL is the same

headers the same (I even added the ones Xojo sends by default to the CURL call & it made no difference)

the CURL command still works
the Xojo code doesnt

Converted the Xojo code to C#
it works

Xojo doesnt

so I’m really out of IDEAS

Could it be a transport protocol issue?
