解析服务器从邮递员那里获取照片（后数据）

Question

我想从邮递员那里发送照片，但出现错误。我该如何解决？

{
    "error": "Unexpected token - in JSON at position 0"
}

我的代码：

Parse.Cloud.define(‘test’, async (req) => {
try {
const Test = Parse.Object.extend(‘Test’)
const obj = new Test()
const { photo } = req.params
let uploadedFile = await new Parse.File(
‘galleryFile’,
photo,
‘image/png’
)
obj.set(‘photo’, uploadedFile)
const data = await obj.save()
return data
} catch (error) {
throw error
}
})

Postman error
