Python Pixabay API

Question

我写了一个脚本，使用Pixabay API从Pixabay下载20000张图片。但在抓取第600张图像后，问题出现了，并显示以下错误：

“文件页面第26行，在页面”true“中，文件页面第144行，在search raise ValueError(resp.text) ValueError中: ERROR 400”"c:/Users/Dell/Desktop/python-pixabay-master/python-pixabay-master/main.py"，“超出有效范围。”

代码：

from pixabay import Image, Video
import pprint
import requests
import shutil

API_KEY = 'myAPIkeys'
image = Image(API_KEY)

j=1
for n in range(1,100):
    ims = image.search(
                q="education",
                lang="en",
                image_type="all",
                orientation="all",
                category="education",
                min_width=0,
                min_height=0,
                colors="",
                editors_choice="false",
                safesearch="false",
                order="popular",
                page=n,
                per_page=200,
                callback="",
                pretty="true"

                )

#hits=ims['total']
#print(hits)    
#print(ims)

    #pp=pprint.PrettyPrinter(indent=4)
    for i in range(0,200):
        payload=ims['hits'][i]['largeImageURL']
        resp = requests.get(payload, stream=True)
        local_file = open(str(j)+"local_image.jpg", 'wb')
        resp.raw.decode_content = True
        shutil.copyfileobj(resp.raw, local_file)
        del resp



        print(str(j)+"URL of image: {}".format(payload))
        j=j+1 
        #urllib.request.urlretrieve(payload,i)

    #pp.pprint(ims)

我已经在postman中尝试过你的API，你可以看到在API中有一个参数页面，所以在你的例子中，所有的图像都是覆盖到第3页的，所以在第4页上，它给出了page is out of valid range error from pixabay。

您可以尝试使用此邮递员链接：https://www.getpostman.com/collections/2823a8aad5ea81b55342

导入它并检查它。

您可以使用exception来处理此错误。

from pixabay import Image
import requests
import shutil

API_KEY = 'API_KEY'
image = Image(API_KEY)

j=1
for n in range(1,100):
    try:
        ims = image.search(
                    q="education",
                    lang="en",
                    image_type="all",
                    orientation="all",
                    category="education",
                    min_width=0,
                    min_height=0,
                    colors="",
                    editors_choice="false",
                    safesearch="false",
                    order="popular",
                    page=n,
                    per_page=200,
                    callback="",
                    pretty="true"

                    )
        for i in range(0, 200):
            payload = ims['hits'][i]['largeImageURL']
            resp = requests.get(payload, stream=True)
            local_file = open(str(j) + "local_image.jpg", 'wb')
            resp.raw.decode_content = True
            shutil.copyfileobj(resp.raw, local_file)
            del resp

            print(str(j) + "URL of image: {}".format(payload))
            j = j + 1
            # urllib.request.urlretrieve(payload,i)

        # pp.pprint(ims)

    except Exception as e:
        print(e)
