问题描述

因此,我想弄清楚如何在Freebase数据库中获取URL的图像。我想要一张旧金山的图像。这就是我得到旧金山话题的方式:

https://www.googleapis.com/freebase/v1sandbox/topic/%2Fen%2Fsan_francisco?key=MY_API_KEY



例如:

  {
text:旧金山天际线,
lang: en,
id:/ m / 04j74yh,
创建者:/ user / carmenmfenn1,
时间戳:2008-09-01T13:37:22.000Z

$ / code>

所以我再次调用GET API来获取图像:



https://www.googleapis.com / freebase / v1sandbox / topic /%2Fm%2F04j74yh?key = MY_API_KEY



这会返回大量关于图片的信息,例如媒体类型,大小等。但我没有看到任何网址。有一些ID(blob id,mid)。我不知道如何继续获取图片的网址。任何想法?



这是完整的回应:

解决方案

由于它没有自己的部分,而是从Topic API文档中引用,但您可以在这里找到必要的信息



网址格式为:

  https://usercontent.googleapis.com/freebase / v1 / image /<图像ID> 


So, I am trying to figure out how to get URL to an image in Freebase database. I want an image of San Francisco. This is how I get the San Francisco topic:

https://www.googleapis.com/freebase/v1sandbox/topic/%2Fen%2Fsan_francisco?key=MY_API_KEY

The response contains images, for example:

{
    text: "San Francisco Skyline",
    lang: "en",
    id: "/m/04j74yh",
    creator: "/user/carmenmfenn1",
    timestamp: "2008-09-01T13:37:22.000Z"
}

So I then call the GET API again to get the image:

https://www.googleapis.com/freebase/v1sandbox/topic/%2Fm%2F04j74yh?key=MY_API_KEY

This returns lots of information about the image such as media type, size etc. But I don't see any URL there. There are some IDs (blob id, mid). I am not sure how to proceed to get a URL to the image. Any ideas?

This is the full response:

https://usercontent.googleapis.com/freebase/v1/image/<image ID>

这篇关于Google Freebase API如何获取图像的URL?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持IT屋!
