PROSAGA码农传奇-swift/objective-C-Vapor一次上传多个文件

<div class =“post-text”itemprop =“text”>
  
    以下示例运行良好，已经多次测试馃馃
  
   <pre class="lang-swift prettyprint-override">
 <code>
 struct MyPayload: Content {
 var somefiles: [File]
}

func myUpload(_ req: Request) -> Future<HTTPStatus> {
 let user: User = try req.requireAuthenticated()
 return try req.content.decode(MyPayload.self).flatMap { payload in
 let workDir = DirectoryConfig.detect().workDir
 return payload.somefiles.map { file in
 let url = URL(fileURLWithPath: workDir + localImageStorage + file.filename)
 try file.data.write(to: url)
 return try Image(userID: user.requireID(), url: imageStorage + file.filename, filename: file.filename).save(on: req).transform(to: ())
 }.flatten(on: req).transform(to: .ok)
 }
}

</code>
 </pre>
  
    顺便说一句，你也可以在函数参数中完全声明你的有效载荷
  
   <pre class="lang-swift prettyprint-override">
 <code>
 func myUpload(_ req: Request, _ payload: MyPayload) -> Future<HTTPStatus> {
 let user: User = try req.requireAuthenticated()
 let workDir = DirectoryConfig.detect().workDir
 return payload.somefiles.map { file in
 let url = URL(fileURLWithPath: workDir + localImageStorage + file.filename)
 try file.data.write(to: url)
 return try Image(userID: user.requireID(), url: imageStorage + file.filename, filename: file.filename).save(on: req).transform(to: ())
 }.flatten(on: req).transform(to: .ok)
}

</code>
 </pre>
  
    唯一的区别是在路由器上声明端点功能
  
   <pre class="lang-swift prettyprint-override">
 <code>
 router.post("upload", use: myUpload)

</code>
 </pre>
  
    VS
  
   <pre class="lang-swift prettyprint-override">
 <code>
 router.post(MyPayload.self, at: "upload", use: myUpload)

</code>
 </pre>
  
    然后在邮递员上传这样的文件
