I am trying to download page source from a given site that heavily uses Ajax / Javascript to Generate the source. What I am trying to do is find a way to get the source downloaded after this occurs in Unity. I am familiar with doing so in a basic C# application using the web browser component or with HtmlAgility Pack LoadFromBrowser method. However, I have tried to add win forms into the application with no success as well as HtmlAgilityPack and neither of those work. When trying to add winforms to the application I get "Could not register the window class, windows error 0" error and a null reference exception. Same goes for HtmlAgilityPack as the LoadFromBrowser I believe uses the webbrowser component. Am I missing something with UnityWebRequest that could get the job done?

How to replace WWW() with UnityWebRequest
I'm a complete beginner in this area, may someone help me?
I currently have:
string s;
...
StartCoroutine(OutputRoutine(new System.Uri(paths[0]).AbsoluteUri));
...
private IEnumerator OutputRoutine (string url){
var output = new WWW(url);
yield return output;
s = output.text;
}
But that gives me a warning:
*warning CS0618: `UnityEngine.WWW' is obsolete: `Use UnityWebRequest, a fully featured replacement which is more efficient and has additional features'*
How I can do what the warning says without changing the way it currently works? I don't want to change anything, just update the code to be more efficient and stop giving me warnings
Additional context, if needed: this code is from an example from [SFB][1], which I'm using to save/load text files.

A method for streaming custom audio from the hard drive
With the deprecation of *WWW.GetAudioClip*, *UnityWebRequestMultimedia.GetAudioClip* seems to be the main way to download custom audio off the internet and play it at runtime. Which is great and all, but what about loading custom audio off the player's hard drive?
Surely there must be some synchronous method for creating an AudioClip using a file off the hard disc; something that doesn't require messing around with web code and coroutines. Is there some way to--for instance--use *File.ReadAllBytes()* at runtime and pass the resulting byte array into an *AudioClip*? (I notice that *[AudioClip.SetData()][1]* expects to receive a float[], which is decidedly not a byte array, and that the *[AudioClip.LoadAudioData()][2]* method seems to...be useless?)
Is *UnityWebRequestMultimedia.GetAudioClip()* really the only game in town? Or is there something a little less cumbersome available for loading custom audio off the hard drive?

See Request of WWW or UnityWebRequest, 403 error only from android in a specific url (GET)
Hello, I have a code that downloads data from a url. I have a problem that one Url gives me error 403 (Forbidden) only from android. When i get the url from editor or Windows build, all works perfectly.
So if i could see the Request that WWW or UnityWebRequest does from android and Windows i would be able to compare whats going wrong.
I tested it with two codes ( WWW and UnityWebRequest) and both give the same result.
i tested it with other urls that contains xml, and it works.

JSON WebRequest works in 2018.2, throws 403 error in 2018.3
Since **Unity2017.2** we've been using a custom build pipeline that can be triggered by sending a JSON webrequest to the pipeline's API (using editor coroutines). I had specifically implemented this request using the **UnityWebRequest** class due to WWW being deprecated in the future. The implementation of this webrequest has worked all the way up to **Unity2018.2.21f1** without issue (see code snippet below).
However, for some reason the exact same implementation returns a **response code 403 (forbidden)** in **Unity 2018.3.4f1**. I've been looking through patch notes and documentation for web requests in 2018.3, but I can't seem to find any significant changes, other than the WWW class being deprecated.
If there's anyone out there who can point me in the right direction, I'd be eternally grateful.

UnityWebRequest.POST calls to an HTTPS url throws "Unknown error" on specific device
Hello, just upgraded our backend server to HTTPS from HTTP, I tested it in the Editor and 4 devices.
All fine except one of the devices, which gave an "Unknown error" error (.error property of the "UnityWebRequest" class). I switched back to HTTP and the error is gone, so it's caused by the HTTPS.
The device is a Huawei Nova 2 and has Android 7.
I've already tryed the .chunkedTransfer = false, and it doesn't work.
Any ideas?

GZIP compression in Unity
Hello!
I'm using UnityWebRequest.Get to pull gzipped assets.
Whether or not I add request.SetRequestHeader("Accept-Encoding", "gzip") to my request, I notice that I get accept-encoding gzip in the response headers. However, the download size is the uncompressed size.
What's going on here?
This link seems to say we shouldn't be setting accept-encoding headers?

How to return value from UnityWebRequest?
I have a script that connects to the database and retrieve data. The GetData function is called by other script. is there a way that I can return the data back to the caller?
public IEnumerator GetData(){

yield return wwww.SendWebRequest();
if (wwww.isNetworkError || wwww.isHttpError){
Debug.Log(wwww.error);
} else {
Debug.Log(wwww.downloadHandler.text);
//How to return the result to the caller?

The method that I know is to call another function in other script to pass the data, but this is a lot more troublesome. Is there any direct way that I can return the data to the caller? Thanks!

Issue assigning JSON Data to Class Structure
Hello there!
Here's a bit of background information:
----------
I'm making a GET request to retrieve JSON data, and I'm trying to store that data into a structure of classes. Printing the retrieved data to the console works, but assigning it to the classes does not (it remains empty in the inspector after the request.)
----------
I’ve split the code into two sections.
1. Makes the web request and attempts to store the data into a class structure.
2. The current class structure
----------
Here is a link to the [JSON Data][1] I’m using.
----------
public class WebRequestTest : MonoBehaviour
{
public string uri = "https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=5min&apikey=demo";
public RootObject rootObj;
void Start()
{
StartCoroutine(GetRequest(uri));
}
IEnumerator GetRequest(string uri)
{
UnityWebRequest req = UnityWebRequest.Get(uri);
yield return req.SendWebRequest();
Debug.Log(req.downloadHandler.text);
rootObj = JsonUtility.FromJson(req.downloadHandler.text);
}
}
Below is the structure for my classes so far. I'm imagining that the issue might be with TimeSeries.dataPeriods.
(TLDR: I wasn't sure whether to use an array, a list, or something else; but I settled on a list.)
[Serializable]
public class RootObject
{
public MetaData metaData;
public TimeSeries timeSeries;
}
[Serializable]
public class MetaData
{
public string Information;
public string Symbol;
public string LastRefreshed;
public string OutputSize;
public string TimeZone;
}
[Serializable]
public class TimeSeries
{
public List dataPeriods;
}
[Serializable]
public class DataPeriod
{
public Data data;
}
[Serializable]
public class Data
{
public string Open;
public string High;
public string Low;
public string Close;
public string Volume;
}
You may have noticed in the Data class that I stored all the numeric data as strings. I thought I'd need to store them this way at first because they are coming from JSON and then convert them later when needed. (Perhaps there is a more elegant way to handle this?)
----------
Final questions:
1. Am I handling comma separated objects the right way by using a list or should I be doing something else?
2. Does anything stand out as to whats preventing the data from being assigned into the RootObject class?
3. If you have any insights about what would be a good way to handle converting the numbers to ints/floats when the class is created, I would love to hear it!
Thank you so much for reading this! I'm going to keep working on this and will post an update when I can.

Red 8x8 Question mark texture global replacement
Hello! There are numerous questions covering this, none with a great answer that I've seen.
I'm building an app heavily reliant on live images from the web, and a caching plugin called unicache. We have had some corrupt files from the backend, and very rare errors with the caching plugin that result in an 8x8 texture being displayed which is a red question mark.
Many of the community answers rely on fixing the underlying problem. We're at a place where that seems to have been solved, but is there a solid way to globally just replace that question mark texture with something more professional?

UnityWebRequestTexture Unable to Load From Directories Containing '#' or '+' Characters

imgObj.transform.localRotation = Quaternion.identity;
imgObj.transform.localScale = Vector3.one;
imgObj.GetComponent().texture = imageTex;
imgObj.GetComponent().enabled = false;
imgObj.GetComponent().enabled = false;
imagesLoaded++;
imageList[i] = imgObj;
}
However, when I try to load images from directories containing the '+' or '#' characters (i.e. "C:\Users\MyUser\Documents\Unity Projects\The+++Folder"), I get the HttpError: "HTTP/1.1 404 Not Found"
Directories containing other special characters like @, &, or = work fine. Using the Replace function to replace the characters with their character entity reference code (i.e., replacing all instances of "+" with "& plus ;") did not fix the problem.
What is the source of this issue, and is there a way around it? I'd rather not be arbitrarily restricted in which valid folder names actually work with my program.
