have a look at unity's manual : https://docs.unity3d.com/Manual/UnityWebRequest.html you can use it to use get and post requests

public void OnSelect() {

var results = db.POST("SERVICE URl", data, Headers);
}
Hear Is db.POST method;
private IEnumerator coroutine;
@Ankit09_Sangani, you are still using the old www system as per your line of code
you should be using the new method: (UnityWebRequest.Post) as per the link to the documentation I provided up above, it should then work ;-)

Thank you so much SpheredCazual
I am quite new in Unity and hololens. how can i pass header UnityWebRequest.post()
I would also be interested in that question, since I would like to retrieve and update the IPD via webrequest.
I have two problems:
GET: I have integrated a unitywebrequest that works well to retrieve the IPD in the editor but fails in the HoloLens. In this request I send the authorization via
UnityWebRequest www = UnityWebRequest.Get(ipdaddress); www.SetRequestHeader("AUTHORIZATION", authorization);
POST: Since I cannot send an "empty" POST request with no form and just the uri parameters in the request uri, I could not figure out how to use unitywebrequest. I wrote a httpwebrequest instead, which again works fine in the editor and updates the IPD. Here I send the credentials via
NetworkCredential usercred = new NetworkCredential("admin", "password"); req.Credentials = usercred;
If I run these requests in the HoloLens, there are debug messages:
Error: could not find assembly System.Private.Networking.dll in which type System.Net.ICredentialsByHost resides. Error: could not find assembly System.Private.Networking.dll in which type System.Net.NetworkCredential resides. Error: could not find assembly System.Private.Networking.dll in which type System.Net.ICredentialsByHost resides Error: could not find assembly System.Private.Networking.dll in which type System.Security.SecureString resides.

In unity project settings make sure InternetClient ,InternetClientServer Capabilities were true.

Thanks a lot for the tips!
@Ankit09_Sangani I have these turned on. The error still appears. The WindowsDevicePortalWrapper might make things much easier but it seems like it doesn't work yet for unity because of the lacking support for .NET4.5.2.
@SpheredCazual : I also found this in the docs and played around but haven't figured out how to provide the formdata, so that the post request is correct. Eg. if my uri should be
http://127.0.0.1:10080/api/holographic/os/settings/ipd?ipd=60000
what should I put in the form.AddField?
form.AddField("ipd", "60000");
and change the url to
http://127.0.0.1:10080/api/holographic/os/settings/ipd

I noticed that all calls above are based on HTTP. If i look at the documentation of UnityWebRequest i noticed that they only talk about standard HTTP calls. Does UnityWebRequest supports SSL? And if not does WWW support it?
WWW, is not a good choice as it does not work on the hololens, I have been using the UnityWebRequest with SSL fine, but the above question was to a local address so there was no need for SSL ;-)

I have been using WWW on a HoloLens without any problems. In my case i connect to an Azure Cloud Service. Does the HoloLens team acknowledge the fact that using UnityWebRequest is the way to go? The reason we started to use WWW again was that we had issues using UnityWebRequest in POST calls from HoloLens.
Hi @SpheredCazual
What is the maximum length of a string in Unity, that can be populated from WWW.text?
Currently i received only 4088 Char string as response but actual response it is more then 20000 Char string.So, i can't got proper Data... Please help me out ..
thanks
Hello guys!
Check my plugin for Unity, working with promises is better!
https://github.com/proyecto26/RestClient (Supported all platforms)
Also you can see the demo, it’s very easy!
Let me know what you think, Nicholls
Hi guys,
When I use UnityWebRequest, I am able to send HTTP Get Request successfully, but I am fail with HTTPS Get Request even though I checked all permissions for the publish settings.
So my question is that how to send HTTPS request in Hololens? Please help me out
Thanks!
Hey guys,
I read that the wwwForm.headers only contains one header, is there a walk around for 2 headers ( Content-Type : application/json and token : 12345) ? I want to use the post method.
Thanks for your support
