cURLParser is a tool to help translate cURL commands into Best HTTP/2 code. Link to the Unity Asset Store page: https://assetstore.unity.com/packages/tools/network/best-http-2-curl-parser-addon-187305

Setup Guide

This addon doesn't require any installation steps, but it's recommended to import after the Best HTTP/2 package. After importing both packages the cURLParser window can be opened through the Window/Best HTTP/Addons/cURL Parser/Parser Window menu item or with the Ctrl+Alt+R keyboard shortcut.

The cURL Parser Window

  1. cURL Command: Paste your cURL command here.

  2. Request Usage: How and where you want to use the generated code. It can generate code to call a callback upon finishing the request, generate a coroutine or an awaitable async function.

  3. Parse Button: Press this button to parse the command and generate the plugin code.

  4. Generated Code: This is where the generated code shows up. Note that the generated code is just a snippet, it wouldn't compile pasting it into an empty file and you still have to make edits on the code.

  5. Copy to Clipboard Button: Clicking on this going to copy the generated code to the clipboard.


Not all cURL features and flags have an equivalent one with Best HTTP/2. Not all cURL features are parsed and implemented. One example is the file content operator (@) that cURL uses to read a field or other content from a file instead of treating it as a plain textual data.


The picture above uses a cURL command copied from the OneSignal REST API documentation:

curl --include \ --request POST \ --header "Content-Type: application/json; charset=utf-8" \ --header "Authorization: Basic YOUR_REST_API_KEY" \ --data-binary "{\"app_id\": \"YOUR_APP_ID\", \"contents\": {\"en\": \"English Message\"}, \"headings\": {\"en\": \"English Title\"}, \"included_segments\": [\"Subscribed Users\"]}" \ https://onesignal.com/api/v1/notifications

And the addon generates the following code:

async Task SendRequest_onesignalcom_api_v1_notifications()
    var request = new HTTPRequest(new Uri("https://onesignal.com/api/v1/notifications"), HTTPMethods.Post);

    request.AddHeader("Content-Type", "application/json; charset=utf-8");
    request.AddHeader("Authorization", "Basic YOUR_REST_API_KEY");

    string data = @"{""app_id"": ""YOUR_APP_ID"",
""contents"": {""en"": ""English Message""},
""headings"": {""en"": ""English Title""},
""included_segments"": [""Subscribed Users""]}";
    request.RawData = System.Text.Encoding.UTF8.GetBytes(data);

    CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();
        var response = await request.GetHTTPResponseAsync(cancellationTokenSource.Token);
    catch (AsyncHTTPException ex)
        Debug.Log("Status Code: " + ex.StatusCode);
        Debug.Log("Message: " + ex.Message);
        Debug.Log("Content: " + ex.Content);
    catch (TaskCanceledException)
        Debug.LogWarning("Request Canceled!");
    catch (Exception ex)
