Sample 4.1: A single file input
一、定义
示例4.1：单个文件输入
此示例API调用将从Example.psd输入中请求两个不同的输出表示形式：
Example.jpeg是一个新的JPEG格式，宽度为512像素Example.png是新的全尺寸PNG格式
-
curl -X POST \
-
https://image.adobe.io/pie/psdService/renditionCreate \
-
-H 'Authorization: Bearer
<auth_token>' \
-
-H 'Content-Type: application/json' \
-
-H 'x-api-key:
<YOUR_API_KEY>' \
-
-d '{
-
"inputs":[
-
{
-
"href":"
<SIGNED_GET_URL>",
-
"storage":"external"
-
}
-
],
-
"outputs":[
-
{
-
"href":"
<SIGNED_POST_URL1>",
-
"width": 512,
-
"storage":"external",
-
"type":"image/jpeg"
-
},
-
{
-
"href":"
<SIGNED_POST_URL2>",
-
"storage":"external",
-
"type":"image/png"
-
}
-
]
-
}'
关于<SIGNED_GET_URL>怎么传我目前还不清楚.Input and Output file storage
Clients can use assets stored on one of the following storage types: External: AWS S3: By using a presigned GET/PUT URL Azure: By generating a SAS (Shared Access Signature) for upload/download Dropbox: Generate temporary upload/download links using https://dropbox.github.io/dropbox-api-v2-explorer/

三、返回
调用此API将初始化一个异步作业并返回一个包含href的响应。使用href中的值来轮询作业的状态。
为什么令牌无效？重新生成的，Welcome to the Photoshop API! 访问也是正常的
