Question

我在Jupyter Notebook中有一个Azure Maps API调用，该调用返回.png格式的地图图块。该调用的效果很好，但我不知道如何将其显示为图像而不是二进制文本。

-API调用：

import requests
from ipywidgets import Image

url = "https://atlas.microsoft.com/map/static/png"

querystring = {
    "api-version":"1.0",
    "subscription-key":"<myRedactedAPIkey>",
    "layer":"basic",
    "zoom":"5",
    "center":"-122.3950336,47.566848",
    "height":"600",
    "width":"600",
    "pins":"default||-121.95066667 45.9135|-121.062 46.707",
    "format":"png",
    "path":"ra300||-122.3950336 47.566848"
}

payload = ""
headers = {
    'cache-control': "no-cache"
    }

response = requests.request("GET", url, data=payload, headers=headers, params=querystring)

print(response.text)

结果：

�PNG

希望：

有什么建议吗？谢谢。

EDIT2 ：这是有效的查询。感谢大家的帮助。

import requests
from IPython.display import Image, display

url = "https://atlas.microsoft.com/map/static/png"
payload = ""
querystring = {
        "api-version":"1.0",
        "subscription-key":"<myApiKeyRedacted>",
        "format":"png",
        "layer":"basic",
        "zoom":"5",
        "center":"-122.3950336,47.566848",
        "height":"600",
        "width":"600",
        "pins":"default||-121.95066667 45.9135|-121.062 46.707",
        "path":"ra300000||-122.3950336 47.566848"
    }
headers = {
    'cache-control': "no-cache"
    }

r = requests.get(url,data=payload, headers=headers, params=querystring, stream=all)

display(Image(r.content))

Answer 1

这是最终工作的结果：出现了由stream=all，Ipython.display和.content组成的组合。

import requests
from IPython.display import Image, display

url = "https://atlas.microsoft.com/map/static/png"
payload = ""
querystring = {
        "api-version":"1.0",
        "subscription-key":"<myApiKeyRedacted>",
        "format":"png",
        "layer":"basic",
        "zoom":"5",
        "center":"-122.3950336,47.566848",
        "height":"600",
        "width":"600",
        "pins":"default||-121.95066667 45.9135|-121.062 46.707",
        "path":"ra300000||-122.3950336 47.566848"
    }
headers = {
    'cache-control': "no-cache"
    }

r = requests.get(url,data=payload, headers=headers, params=querystring, stream=all)

display(Image(r.content))

Answer 2

由于response.text似乎是有效的PNG图片，并且您正在使用ipywidgets Image，因此您尝试使用它吗？

widgets.Image(
    value=response.text,
    format='png',
    width=300,
    height=400,
)

如何在Jupyter Notebook中显示来自API响应的图像？
