Post to a Server
----------------

This program posts data to a service. [Full source][post_example].

```java

In this case, you could want to document how that external API *should* look like. What *path operation* it should have, what body it should expect, what response it should return, etc.

## An app with callbacks { #an-app-with-callbacks }

Let's see all this with an example.

Imagine you develop an app that allows creating invoices.

import (
	"context"
	"fmt"
	"net/http"
	"net/url"
	"os"
	"testing"
	"time"
)

func niceError(code APIErrorCode) string {
	// Special-handle ErrNone
	if code == ErrNone {
		return "ErrNone"
	}

	return fmt.Sprintf("%s (%s)", errorCodes[code].Code, errorCodes[code].Description)
}

func TestDoesPolicySignatureMatch(t *testing.T) {
	_, fsDir, err := prepareFS(t.Context())
	if err != nil {
		t.Fatal(err)

  parsed_args = parser.parse_args()
  if not parsed_args.print and not parsed_args.xml_out_path:
    raise TypeError('`--print` or `--xml-out-path` must be specified')

  return parsed_args

              verbose: bool = False) -> ResultDictType:
  """Finds ResultStore links, and tries to determine their status."""

        int len = clean.length();
        byte[] out = new byte[len / 2];
        for (int i = 0; i < len; i += 2) {
            out[i / 2] = (byte) Integer.parseInt(clean.substring(i, i + 2), 16);
        }
        return out;
    }
