### Posting a File ([.kt][PostFileKotlin], [.java][PostFileJava])

It's easy to use a file as a request body.

    ```kotlin
      private val client = OkHttpClient()

      fun run() {
        val file = File("README.md")

        val request = Request.Builder()

          echo "OUTPUT<<EOF" >> $GITHUB_ENV
          echo "$OUTPUT" >> $GITHUB_ENV
          echo "EOF" >> $GITHUB_ENV
      - name: Comment on PR if check failed
