我正在尝试使用Lightroom API从Lightroom Cloud存储中检索图像。我有oauth在工作，我可以做任何事情，但得到一个副本。
我写了下面的脚本来说明我的问题。我可以获取我的目录元数据来获取目录id。我可以使用该目录id来获取资产id。我甚至可以请求该特定资产的元数据，但一旦我尝试获取格式副本，就会出现错误。
# (All personal ids/tokens removed)
CLIENTID=MYCLIENTID
TOKEN=ATOKENFROMOAUTH2
CATALOG_ID=MYCATALOID
AN_ASSET_ID=ANASSETID
# These three all work.
CATALOG_URL="https://lr.adobe.io/v2/catalog"
ASSETS_URL="https://lr.adobe.io/v2/catalogs/${CATALOG_ID}/assets"
ASSET_URL="https://lr.adobe.io/v2/catalogs/${CATALOG_ID}/assets/${AN_ASSET_ID}"
# This one does not.
RENDITION_URL="https://lr.adobe.io/v2/catalogs/${CATALOG_ID}/assets/${AN_ASSET_ID}/renditions/2048"
FILE=`mktemp`
wget --content-on-error -S -O$FILE --header="x-api-key: $CLIENTID" --header="authorization: Bearer $TOKEN" $RENDITION_URL
#tail -n +2 $FILE | jsonpp
cat $FILE
wget的输出：

我已经尝试了很多方法。我看过Adobe的示例代码，但我一直无法自己解决这个问题。欢迎提出任何建议。
谢谢你们！
根据HTTP状态代码404和描述显示的not found，您可能需要发出POST请求来生成格式副本(https://developer.adobe.com/lightroom/lightroom-api-docs/api/#operation/generateRenditions)首先从服务器获取格式副本。
