从url获取到了response却无法获取到response中的具体内容，response.text显示{code:0,msg:'limited'}

代码如下

import requests
url = 'https://item-soa.jd.com/getWareBusiness?skuId=100012809042&cat=737,794,798&area=17_1421_1430_7471'
response = requests.get(url)
print(response)

返回结果

<Response [200]>

但如果用response.text替换response会出现如下结果

{code:0,msg:'limited'}

为什么获取不到具体内容？

加个请求头

import requests
url = 'https://item-soa.jd.com/getWareBusiness?skuId=100012809042&cat=737,794,798&area=17_1421_1430_7471'
headers = {
    'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36 QIHU 360SE'
}
response = requests.get(url, headers=headers)
print(response.text)
