Takahanga 1: Tikina tō Kī API

Waitohu ki tētahi pūkete Doitong, ka haere ki tō papatohu hei whakaputa i tētahi kī API.

Takahanga 2: Kōkirihia tō Tono Tuatahi

Whakamahia tētahi o ngā tauira waehere i raro nei hei kōkiri i tō karanga API tuatahi.

Utu

E whakamahi ana a Runway Gen4 API i tētahi tauira utu i runga i te whiwhinga (credit). Ka pau ngā whiwhinga i runga i te uaua me te roa o te ihirangi ka whakaputaina.

Ngā Pae API

E wātea ana a Runway Gen4 API mā tō mātou pae GraphQL kōmitimiti.

Pae GraphQL

POST https://api.doitong.com/graphql

Pae REST

POST https://api.doitong.com/v1/text_to_video

Ngā Tawhā

Ngā tawhā e wātea ana mō ngā tono Runway Gen4 API:

Hōputu Whakahoki

He rite tonu te hōputu o ngā whakahoki API katoa:

Whakahoki Angitu

{
  "data": {
    "generatevideo": {
      "id": "abc123xyz",
      "status": "processing",
      "url": null,
      "webhookUrl": "https://your-webhook.com/callback",
      "createdAt": "2024-01-01T00:00:00Z"
    }
  }
}

Whakahoki Kua Oti

    "generatevideo": {
      "id": "abc123xyz",
      "status": "completed",
      "url": "https://cdn.doitong.com/outputs/abc123xyz.mp4",

      "createdAt": "2024-01-01T00:00:00Z"
    }
  }
}

Whakahaere Hapa

E whakamahi ana te API i ngā waehere tūnga HTTP paerewa, ā, ka whakahokia mai he karere hapa taipitopito.

Ngā Waehere Hapa Noa

Hōputu Whakahoki Hapa

{
  "errors": [
    {
      "message": "Insufficient credits for this operation",
      "extensions": {
        "code": "INSUFFICIENT_CREDITS",
        "creditsRequired": 100,
        "creditsAvailable": 50
      }
    }
  ]
}

Matau Tukutuku

Whiwhi whakamōhiotanga hāora-tūturu ina oti te whakaputa i tō text to video.

Whakarite Matau Tukutuku

Include a <code>webhookUrl</code> parameter in your request to receive a POST notification when processing is complete.

Raraunga Matau Tukutuku

{
  "id": "abc123xyz",
  "status": "completed",
  "url": "https://cdn.doitong.com/outputs/abc123xyz.mp4",
  "service": "runway",
  "createdAt": "2024-01-01T00:00:00Z",

    "width": 1920,
    "height": 1080
  }
}

Haumarutanga Matau Tukutuku

Kei roto i ngā tono matau tukutuku katoa he pane waitohu hei whakamana:

X-Doitong-Signature: sha256=abc123...

Ngā Tepe Tere

Hei whakarite i te whakamahinga tika me te pūmautanga o te pūnaha, ka whai mana ēnei tepe tere:

Ngā Tikanga Pai

1. Whakapai ake i ō Tono (Prompts)

Tuhia he tono mārama, he tono whakaahua hoki kia whiwhi ai i ngā hua pai rawa atu:

• Be specific about visual elements, style, and mood
• Include details about lighting, camera angles, and composition
• Avoid contradictory or impossible requests

2. Whakahaerehia te Tukatuka Tukutahi-kore (Async)

He tukutahi-kore te mahi whakaputa. Whakaritea he pūnaha tirotiro (polling), he matau tukutuku rānei:

// Polling example
async function pollStatus(jobId) {
  let status = 'processing';
  while (status === 'processing') {
    await sleep(2000); // Wait 2 seconds
    const result = await checkJobStatus(jobId);
    status = result.status;
  }
  return result;
}

3. Whakaora Hapa

Whakaritea he arorau ngana-anō me te whakaroa haere (exponential backoff):

async function retryWithBackoff(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await sleep(Math.pow(2, i) * 1000);
    }
  }
}

4. Aroturuki i te Whakamahinga Whiwhinga

Aroturukihia tō whakapau whiwhinga kia kore ai e haukotia te mahi:

• Check credit balance before large batch operations
• Set up alerts for low credit thresholds
• Implement credit-aware request queuing
