VK Web API(简单) [英] VK Web API (simple)

问题描述

我想调用方法photos.get"并从VK社区检索照片.问题是我在访问网址.例如，当我浏览某个社区时，我最终会得到一个类似http://vk.com/picsa".我需要一个可以作为参数传入的数字，而不是这个 picsa.如何从 URL 中获取 owner_id?

I would like to call the method "photos.get" and retrieve photos from a VK community.The problem is that I am unable to view the oid i.e owner_id( one of the parameters required for the request) when I visit the URL. For example, when I browse a certain community, I end up getting a URL like "http://vk.com/picsa".Instead of this picsa, I require a number that can be passed in as an argument. How do I get the owner_id instead from the URL?

推荐答案

您可以使用 groups.getById API 方法.它不需要任何身份验证:

You can use groups.getById API method. It does not require any authentication:

https://api.vk.com/method/groups.getById?group_ids=picsa

您将获得 JSON 格式的默认组实体:

You will get the default group entity in JSON format:

{
    "response": [
        {
            "gid": 37460919, 
            "name": "AMERICA", 
            "screen_name": "picsa", 
            "is_closed": 0, 
            "type": "page", 
            // photos of different size go here
        }
    ]
}

现在，您可以提取社区 ID (gid) 并将能够在其他 API 请求中使用它.您可以同时获取有关多个社区的信息 - 您需要用逗号对它们进行枚举(/method/groups.getById?group_ids=picsa,othergroup,somename).

Now, you can extract the community's ID (gid) and will be able to use it in other API requests. You can get information about several communities at the same time - you need to enumarate them with commas (/method/groups.getById?group_ids=picsa,othergroup,somename).

当您使用 photos.get 方法时，请记住，VK 使用社区和页面的否定 ID 值.

When you work with photos.get method, keep in mind, that VK uses negative ID values for communities and pages.

例如，
/method/photos.get?owner_id=123456789 表示用户 123456789 的照片"和
/method/photos.get?owner_id=-123456 表示社区 123456 的照片".

For example,
/method/photos.get?owner_id=123456789 means "photos of user 123456789" and
/method/photos.get?owner_id=-123456 means "photos of community 123456".
