facebook - 如何在 Facebook 批量 API 请求中指定 API 版本？

Question

Facebook 批量 API 请求允许调用者在单个 HTTP POST 中指定多个 API 端点。

发帖到基本 URL:https://graph.facebook.com .

帖子的正文包含一个 JSON 散列，其中包含要在“relative_url”字段中调用的相对 URL，例如“我/饲料”。

如何在此调用中指定 API 版本？

例如，要打 2.2 版本的 API，我是否要发布到 https://graph.facebook.com/v2.2/？还是在 relative_url 中指定“v2.2/me/feed”？

截至 2015 年 2 月 26 日，Facebook API 文档在这一点上并不清楚: https://developers.facebook.com/docs/graph-api/making-multiple-requests

您可能必须输入相对 url。这是一个 example来自营销批处理 API 文档

curl -F 'access_token=______' 
  -F 'test1=@./test1.jpg'  
  -F 'batch=[
             {
              "method": "POST",
              "name": "create_creative",
              "relative_url": "<API_VERSION>/act_187687683/adcreatives",
              "attached_files": "test1",
              "body": "title=Test title&body=Test body&link_url=http://www.test12345.com&image_file=test1.jpg"
             },
             {
              "method": "POST",
              "relative_url": "<API_VERSION>/act_187687683/adgroups",
              "body": "campaign_id=6004163746239&redownload=1&bid_type=CPC&bid_info={\"clicks\":150}&creative={\"creative_id\":\"{result=create_creative:$.id}\"}&targeting={\"countries\":[\"US\"]}&name=test1"
             },
             {
              "method": "POST",
              "relative_url": "<API_VERSION>/act_187687683/adgroups",
              "body": "campaign_id=6004163746239&redownload=1&bid_type=CPC&bid_info={\"clicks\":150}&creative={\"creative_id\":\"{result=create_creative:$.id}\"}&targeting={\"countries\":[\"GB\"]}&name=test2"
             },
             {
              "method": "POST",
              "relative_url": "<API_VERSION>/act_187687683/adgroups",
              "body": "campaign_id=6004163746239&redownload=1&bid_type=CPC&bid_info={\"clicks\":150}&creative={\"creative_id\":\"{result=create_creative:$.id}\"}&targeting={\"countries\":[\"IE\"]}&name=test3"
             }
            ]' https://graph.facebook.com/

我假设这对其他请求也很常见。

1.) 来自here

Pre-pend the version identifier to the start of the request path. For example, here's a call to v2.2:

GET graph.facebook.com
  /v2.2/me

This works for all versions, in this general form:

GET graph.facebook.com
  /vX.Y/{request-path}

2.) 把它放在 url 中似乎是为了 Dialogs and Social plugins

Dialogs

Versioned paths aren't just true for API endpoints, they're also true for dialogs and social plugins. For example, if you want to generate the Facebook Login dialog for a web app, you can prepend a version number to the endpoint that generates the dialog:

https://www.facebook.com/v2.0/dialog/oauth?
  client_id={app-id}
  &redirect_uri={redirect-uri}

Social Plugins

If you're using the HTML5 or xfbml versions of our social plugins, the version rendered will be determined by the version specified when you're initialising the JavaScript SDK.

If you're inserting an iframe or plain link version of one of our plugins, you'd prepend the version number to the source path of the plugin:

<iframe
 src="//www.facebook.com/v2.0/plugins/like.php?href=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2Fplugins%2F&amp;width&amp;layout=standard&amp;action=like&amp;show_faces=true&amp;share=true&amp;height=80&amp;appId=634262946633418" scrolling="no" frameborder="0" style="border:none; overflow:hidden; height:80px;" allowTransparency="true"> </iframe>
