Web API : what is the post key value ?

Web API : what is the post key value ?
Hello Simon

I am testing the web API. I have an issue, and have not been able to see where is the answer on your site; sorry if I just need to change glasses..

What is the value of the key when sending a POST ?

As an example : I have created a file named dsfTranscode.txt which contains the only line
prop stream.transcode=flac:wav24, dsf:wav24;176

This file is on my Synology, on the web server directory.

I want call the web API. So here is my script.
But what should I put instead of xxx ???

Many Thanks !

$.ajax({
type: "POST",
url: "http://192.168.73.22:9790/",
data: {xxx:"dsfTranscode.txt"},
dataType: "text",
success: function(retour) {}
}); // end ajax function

I haven't used AJAX myself. From a quick web search, I think it should be something like:

$.ajax({
type: "POST",
url: "http://192.168.73.22:9790/",
data: "prop stream.transcode=flac:wav24, dsf:wav24;176",
dataType: "text",
success: function(retour) {}
}); // end ajax function

In my understanding, a POST call is always sets of key & value

In the case of ajax, it is key:value all sent as a JSON string

In the case of an input field, it is <INPUT name="key"> and the value is in the field

For me, unless I am confused, "prop stream.transcode=flac:wav24, dsf:wav24;176" is the value; but what is the associated key ?

If I look at your webpage for managing minimserver, it seems the key is "sub". I will try this

No, it does not work.

I am using cocoArestClient
I send a post request to http://192.168.73.22:9790/ with key sub and value prop stream.transcode=flac:wav24, dsf:wav24;176
I put the header Content-type to text/plain

It returns "Request content missing"

There is something I don't get here.

There is not always a key for a POST request. This depends on the content type. For a content type of text/plain, there is no key.

Under Body in CocoaRestClient, you need to check 'Raw input'. This gives you an input field without keys. I have tried doing this in CocoaRestClient with a content type of text/plain and it is working for me.

It works for me too !

I had never really noticed the raw input checkbox. Will try with an ajax call.

Thank you , Simon !

Still struggling with ajax call. Now facing CORS issue (the fact that the server is on a different port means cross-origin)

Actually, what I want to do, because of the fact that Lumin app does not recognizes what format the renderers accepts (so dsf:-/wav24;176 does not work) is a html file with ajax call, which I can use from my iPad without the need of a laptop, to switch from direct dsf to dsf conversion (I guess there is no iPad app to control minimserver parameter :-)

Basically, I want to reproduce your nice web access page, but with more parameters than just the content directory.

I understand and this seems like a good idea that might also be useful for other people. I haven't done any AJAX programming so I can't offer any advice on this. Perhaps you could get some help on an AJAX developer forum.

Ajax is not the problem. It is CORS the problem.

I will keep you informed, and if it works, I will share.
