【Photoshop API 】五、 实际案例：PSD文件转换生成新的图像格式

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 ' \
  -H 'Content-Type: application/json' \
  -H 'x-api-key: ' \
  -d '{
  "inputs":[
    {
      "href":"",
      "storage":"external"
    }
  ],
  "outputs":[
    {
      "href":"",          
      "width": 512,
      "storage":"external",
      "type":"image/jpeg"      
    },
    {
      "href":"",
      "storage":"external",
      "type":"image/png"
    }
  ]
}'

关于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
