有没有办法以编程方式获取Bing背景图像?

Bing的API似乎没有提供这样的功能,也许还有另一种方式?

我认为最好的方法是模仿他们通过AJAX调用自己做的方式。

他们调用此URL并通过XML反序列化提取信息。

XML:http://www.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1&mkt=en-US

JSON:http://www.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1&mkt=en-US

RSS:http://www.bing.com/HPImageArchive.aspx?format=rss&idx=0&n=1&mkt=en-US

mkt属性显然可以更改为与'en-US'不同的区域,但如果您不关心特定区域,也可以完全取消选择。

请注意,添加到图像名称的_1366x768.jpg后缀似乎可以修改为不同的分辨率(如全高清和其他可能的_1920x1080.jpg)。

以下是截至2013年9月28日的数据转储,采用XML格式。

简单的PowerShell,放入文件夹,在Windows任务计划程序中创建日常任务,脚本将图像保存在其运行文件夹中,然后在桌面背景设置中选择该文件夹作为背景。

[xml]$doc = (New-Object System.Net.WebClient).DownloadString("https://www.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1&mkt=ru-RU")
$url = $doc.images.image.url
$url = "https://www.bing.com/" + $url -replace "_1366x768","_1920x1200"

Write-Output $url

$fileName = Split-Path $url -leaf
$output = "$PSScriptRoot\$fileName"

$start_time = Get-Date
Invoke-WebRequest -Uri $url -OutFile $output
Write-Output "Saved to: $output Time taken: $((Get-Date).Subtract($start_time).Seconds) second(s)"

让我告诉你如何使用javascript和php获取当天的日常壁纸,

试试这个js代码:

<script>
      fetch('https://techytricks97.000webhostapp.com/')
      .then(response => response.text())
      .then(text=>{document.body.style.background="url('"+text+"')";document.body.style.backgroundSize='cover';});
</script>

这个脚本将当天的日常图像设置为html文档的背景(您可以根据您的使用情况进一步修改它)。

这个链接 - https://techytricks97.000webhostapp.com每天返回当天的bing壁纸。

fetch()https://techytricks97.000webhostapp.com获取今天bing图像的网址,text=>{document.body.style.background="url('"+text+"')";document.body.style.backgroundSize='cover';}将其设置为背景。

注意:Microsoft不允许使用bing daily的图像作为您网站的背景,您可以将其用作手机/桌面墙纸,或其他提及版权的内容。

这是在http://techytricks97.000webhostapp.com上使用的php代码:

<?php
header('Access-Control-Allow-Origin: *');
ini_set('display_errors', 1);
$reg=file_get_contents('https://www.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1&mkt=en-IN');
$reg=json_decode($reg);
$meka=$reg->images[0]->url;
echo('http://www.bing.com'.$meka);
?>

您可以只使用http://techytricks97.000webhostapp.com,也可以在服务器上设置自己的php文件。

另一个注意事项:我没有使用javascript,因为浏览器的同源策略限制它,但允许从我的php文件中取出,因为我已经把header('Access-Control-Allow-Origin: *');in我的PHP代码。我可以使用其他代理,但是他们的流量很高(我的网站一天几乎没有任何点击)。

如果您使用的是任何其他语言,则只需阅读此文件(http://techytricks97.000webhostapp.com

看看bing-desktop-wallpaper-changer上的Github。该脚本是用python编写的,我希望你在那里找到答案。

#!/usr/bin/python
#-*- coding: utf-8 -*-

import os
import urllib
import urllib2
from bs4 import BeautifulSoup

# Get BingXML file which contains the URL of the Bing Photo of the day
# idx = Number days previous the present day. 0 means current day, 1 means       yesterday, etc
# n = Number of images predious the day given by idx
# mkt denotes your location. e.g. en-US means United States. Put in your  country code
BingXML_URL = "http://www.bing.com/HPImageArchive.aspx?     format=xml&idx=0&n=1&mkt=en-US"
page = urllib2.urlopen(BingXML_URL)
BingXML = BeautifulSoup(page, "lxml")

# For extracting complete URL of the image
Images = BingXML.find_all('image')
ImageURL = "https://www.bing.com" + Images[0].url.text
ImageName = Images[0].startdate.text+".jpg"

urllib.urlretrieve(ImageURL, ImageName)

看一下Github项目的详细代码

这是一个简单的Python脚本,只需使用requestsjson即可获取当天的Bing照片:

import requests
import json

BING_URI_BASE = "http://www.bing.com"
BING_WALLPAPER_PATH = "/HPImageArchive.aspx?format=js&idx=0&n=1&mkt=en-US"

# open the Bing HPImageArchive URI and ask for a JSON response
resp = requests.get(BING_URI_BASE + BING_WALLPAPER_PATH)

if resp.status_code == 200:
    json_response = json.loads(resp.content)
    wallpaper_path = json_response['images'][0]['url']
    filename = wallpaper_path.split('/')[-1]
    wallpaper_uri = BING_URI_BASE + wallpaper_path

    # open the actual wallpaper uri, and write the response as an image on the filesystem
    response = requests.get(wallpaper_uri)
    if resp.status_code == 200:
        with open(filename, 'wb') as f:
            f.write(response.content)
    else:
        raise ValueError("[ERROR] non-200 response from Bing server for '{}'".format(wallpaper_uri))
else: 
    raise ValueError("[ERROR] non-200 response from Bing server for '{}'".format(BING_URI_BASE + BING_WALLPAPER_PATH))

这会将TurtleTears_EN-US7942276596_1920x1080.jpg等文件写入执行脚本的同一目录。当然,可以在这里调整一大堆东西,但可以轻松地完成工作。

我最后决定在Python 3中编写一个脚本来从xml存档中获取最多的图像(16)。

所以现在我可以毫不费力地存档图像。只需运行Python脚本。 我将图像组织成年/月文件夹,如下所示:2018> 12月12日> 2018-12-06.jpg

这个脚本进入我的Bing Wallpapers文件夹。 (在我的图片文件夹中)

import urllib.request as urllib
import json
from datetime import date
from dateutil import parser
import sys,os

months = "January","Febuary","March","April","May","June","July","August","September","October","November","December"

def downloadBingImages(start):
    try: data = urllib.urlopen("https://www.bing.com/hpimagearchive.aspx?format=js&idx=%i&n=8&mkt=en-NZ"%start).read()
    except: sys.exit()
    e = json.loads(data.decode())
    images = e["images"]

    for image in images:
        d = parser.parse(image["startdate"]) # parse("20181206")

        filename = str(d.date())+".jpg"                         #                  2018-12-06.jpg
        folder = "%i/%i %s/"%(d.year,d.month,months[d.month-1]) # 2018/12 December/
        file = folder+filename                                  # 2018/12 December/2018-12-06.jpg

        if not os.path.exists(folder): os.makedirs(folder)
        exists = os.path.isfile(file)

        url = "https://www.bing.com"+image["urlbase"]+"_1920x1200.jpg"
        print(("downloading","exists")[exists],filename,url)
        if not exists:
            try: urllib.urlretrieve(url,file)
            except: sys.exit()

    print()

# downloads the 16 latest bing images

# update wallpaper after a week from current
wallpaper = getWallpaper()
if wallpaper.startswith(os.getcwd()): # has to be in script directory
    try: wallpaperDate = parser.parse(os.path.splitext(os.path.basename(wallpaper))[0])
    except: sys.exit() # not using an image with a parsable date

    t = date.today()
    if (t-wallpaperDate.date()).days>=7: # been a week or longer
        setWallpaper(os.path.abspath("%i/%i %s/"%(t.year,t.month,months[t.month-1])+str(t)+".jpg")) # .../2018/12 December/2018-12-14.jpg

附:上面的脚本使用&mkt=en-NZ作为新西兰图像。 您可以查看其他国家here的市场代码。

您还可以查看自2009年以来针对不同国家here存档的所有图像。 (仅限1366x768)

主要人物将脚本添加到任务计划程序以在登录时运行。 (或每日/每周)

创建基本任务 程序/脚本:python(如果它不在你的env路径中,则为C:\ Python34 \ python.exe) 参数:“path / to / your / script.py” 开始于:“path / to / your”

UPDATE! (2019年3月) 2019-03-10的图像在xml和rss格式中都给出了错误的startdate(20190309)。 改用Json格式。 (因为它给出了准确的日期)

使用来自@Siv的URL,这是一个更新<div class="bgimg" id="background">的JavaScript示例

function GetImageURL(ans) {
    var suffix = ans.images[0].url 
    document.getElementById("background").style.backgroundImage = 'url("' + 
    'http://bing.com/' + suffix + '"'
}

function GetJSON() {
    var xmlhttp = new XMLHttpRequest()
    var url = "https://www.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1"

    xmlhttp.onreadystatechange = function () {
        if (this.readyState == 4 && this.status == 200) {
            var ans = JSON.parse(this.responseText);
            GetImageURL(ans);
        }
    };
    xmlhttp.open("GET", url, true);
    xmlhttp.send();
}


window.onload = function () {
    GetJSON()
}

这堂课的CSS是:

.bgimg {
    height: 100%;
    position: relative;
    opacity: 0.95;
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;

你可以在Linux机器上使用python和wget来做到这一点:

import os # import the os package
os.system("wget -O index.html http://www.bing.com") # download the bing index
str1 = open('index.html', 'r').read() # extract the file path using split
str2=str1.split("g_img={url: \"")[1]
str3=str2.split(".jpg")[0]
os.system("wget -O daily_im.jpg http://www.bing.com" + str3 + ".jpg") # donwload the daily image

它以名称daily_im.jpg下载本地目录中的每日bing背景。您可以将所有内容放在script.py上并以编程方式启动它。

BING IMAGE的JSON格式

我找到了一种获取当天Bing Image的JSON格式的方法

http://www.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1

Note

n=你想要的图像的数量(你可以使用整数), mkt=您的位置(例如:en-US)


Here is the JSON output looks like

使用urlimages[]

并将其添加到'http://bing.com'

编辑09/27/2018:http://www.istartedsomething.com/bingimages响应404周。它可能不再存在。 :-(

你可以使用istartedsomething.com's Bing Image Archive。这是一个非官方的Bing Image Archive。它使用自制端点,有助于检索图像:

GET /bingimages/getimage.php?id=<image_id>

id是一个字符串,包含图像发布的日期和发布图像的国家/地区。 id必须遵守以下格式:YYYYMMDD-xx,其中:

  • YYYY是一年,用四位数字写成。
  • MM是月份,用两位数字写成。
  • DD是一天,用两位数字写成。
  • xx是国家指标。 Bing Image Archive目前支持以下国家: au:澳大利亚。 br:巴西。 ca:加拿大。 cn:中国。 de:德国。 fr:法国。 gb:英国。 jp:日本。 nz:新西兰。 uk:英国。 us:美利坚合众国。

如果它有一些信息,它返回一个有用的JSON对象,如果没有任何信息,则返回false。

示例1:检索2014年5月24日在新西兰发布的Bing日常图像

图片ID为20140524-nz,因为要求的图片发布于2014年05月24日,并在新西兰出版,其国家指标为nz

http://www.istartedsomething.com/bingimages/getimage.php?id=20140524-nz返回以下JSON:

{
    "url":"\/az\/hprichbg\/rb\/LakeMagadiFlamingos_ROW9792683076_1366x768.jpg",
    "region":"nz",
    "date":"2014-05-24",
    "copyright":"Flamingos take flight, Lake Magadi, Kenya (\u00a9 Bobby Haas\/Getty Images)(Bing New Zealand)",
    "imageurl":"http:\/\/www.istartedsomething.com\/bingimages\/cache\/LakeMagadiFlamingos_ROW9792683076_1366x768.jpg",
    "hotspots":[],
    "video":[]
}

您可以使用imageurl字段或url(Bing URL路径)字段来获取图像。

示例2:检索1998年7月12日在法国发布的Bing日常图像

图片ID为19980712-fr,因为要求的图片于1998年12月7日发布,并在法国出版,其国家指标为fr

http://www.istartedsomething.com/bingimages/getimage.php?id=19980712-fr返回false因为1998年7月12日法国没有Bing Daily Image(Bing此时甚至不存在)。

微软最近发布了适用于Windows 7的Bing Dynamic Theme,其中包含an RSS Feed with links to Bing wallpapers

还有一个Python script试图加载Bing网站并猜测正确的图像URL,但根据我的经验,它通常会产生比RSS提供的图像分辨率低的图像。

我迟到了,但万一有人需要PHP实现:我写了一个简单的类来处理这个过程:

我也喜欢Bing图像,但他们的应用程序太臃肿,无法下载图像。在分析了与fiddler的连接后,我编写了这段代码。 1920x1200嵌入了Bing徽标,但较低的分辨率没有它。

您可以让窗口显示您设置的图像文件夹中的随机图像,因此当您每天下载它们时,它会向您显示更多随机图像。如果你确实保留了“imageDir”,你需要更改该文件夹的权限,否则它将崩溃,我没有理会捕获错误。最后,如果要将壁纸设置为今天的图像,则可以取消注释行,或者可以创建一个任务来运行程序,比如登录后一分钟。

我看到很多人也在要求新的RSS链接,只需将URL中的format参数更改为“rss”即可。

RSS:http://www.bing.com/HPImageArchive.aspx?format=rss&idx=0&n=1&mkt=en-US

这个JavaScript将通过将div的背景图像更改为当天bing图像的背景来回答“如何处理api”。

function PullBackground() {
    var ajaxRequest = new XMLHttpRequest(), background = ''; 
    ajaxRequest.open('POST', "http://www.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1&mkt=en-US", true);
    ajaxRequest.setRequestHeader("Connection", "close");
    ajaxRequest.send('');
    ajaxRequest.onreadystatechange = function () {
        if (ajaxRequest.readyState == 4) {
            background = ajaxRequest.responseText;
            var res = background.split("<url>"); 
            var res1 = res[1].split("</url>");
            background = res1[0];

            document.getElementById('NameOfTheDivToChange').style.backgroundImage = "url('http://bing.com" + background + "')"
            document.getElementById('NameOfTheDivToChange').style.backgroundSize = "100%";
        }
    }
