Question

向GET请求时

https://apicache.vudu.com/api2/?_type=contentSearch&contentEncoding=gzip&contentId={}&dimensionality=any&followup=ultraVioletability&followup=longCredits&followup=superType&followup=episodeNumberInSeason&followup=advertContentDefinitions&followup=tag&followup=hasBonusWithTagExtras&followup=subtitleTrack&followup=ratingsSummaries&followup=geneGenres&followup=seasonNumber&followup=trailerEditionId&followup=genres&followup=usefulStreamableOffers&followup=walmartOffers&followup=preOrderOffers&followup=editions&followup=merchandiseContentMaps&followup=promoTags&followup=advertEnabled&format=application%2Fjson

从AWS ，我间歇性地收到以下错误：

ContentDecodingError: ('Received response with content-encoding: gzip, but failed to decode it.', error('Error -3 while decompressing: incorrect header check',))

示例：

requests.get(url.format('832504'))
<Response [200]>
requests.get(url.format('460398'))
<Response [200]>
requests.get(url.format('27616'))
<Response [200]>
requests.get(url.format('23657'))
<Response [200]>
requests.get(url.format('8661'))
ContentDecodingError...
requests.get(url.format('14250'))
<Response [200]>
requests.get(url.format('516307'))
ContentDecodingError...
requests.get(url.format('10366'))
<Response [200]>

我尝试了不同的标头组合（包括此处的建议：https://github.com/requests/requests/issues/3849）并删除了contentEncoding=gzip参数（返回502状态代码）。

考虑到该API在我的PC上可以正常使用，也许Vudu和AWS之间存在一些冲突？

我认为这是当前的python请求库限制（或设计行为，请参见here）

因此，您必须使用resp.raw来获取原始字节。（注意：要访问resp.raw，还需要stream=True）。

resp = session.get(url, stream=True)
data = resp.raw.read()

收到内容编码为gzip的响应，但无法解码
