const hash1 = await generateRequestHash("https://api.example.com/data", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ name: "test" })
});

// With Request object
const request = new Request("https://api.example.com/data", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ name: "test" })
});
const hash2 = await generateRequestHash(request);
