GoogleDrive + Alamofire：上传带有属性的文件 [英] GoogleDrive + Alamofire: Uploading a file with properties
问题描述
我试图通过Swift 2 / Alamofire将文件+参数上传到Google云端硬盘。在下面的代码中，我改变了一行：
https://www.googleapis.com/upload/ drive / v3 / files？uploadType = multipart
改为：
https://www.googleapis.com/upload/drive/v3/files
文件上传到Google没有名字。否则，文件上传将失败，并具有相同的通用代码：
错误域= com.alamofire.error代码= -6003响应状态代码是不可接受的：400UserInfo = {NSLocalizedFailureReason =响应状态代码是不可接受的：400}
我希望能够上传文件的名称和潜在的其他参数。我知道我以某种方式改变了分段上传，但我不知道我做错了什么。
func postBinaryToGdriveSimple（token：String，callback：Bool - > Void）{
var returnedId：String！
let path = NSBundle.mainBundle（）。pathForResource（drawing，ofType：bin）
let bindata：NSData = NSData（contentsOfURL：NSURL（fileURLWithPath：path！）） ！
let parameters：[String：String] = [title：SomeFileName]
let headers = [Authorization：Bearer \（token）]
upload（
.POST，
https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart，

//追加二进制文件请求
multipartFormData.appendBodyPart（data：bindata，name：upload，fileName：drawing.bin，mimeType：application / octet-流）
}，

dispatch_async（dispatch_get_main_queue（））{
let percent =（float（totalBytesWritten）/ Float（totalBytesExpectedToWrite））
// progress（percent：percent）
print（................ \\ \\（百分号））
}
}
upload.validate（）
upload.responseJSON {
switch response.result {
case。成功（让数据）：
print（response）
print（Validation Successful）
让json = JSON（data）

print（......上传文件的id是\（returnedId））
回调（true）
case .Failure （让错误）：
print（error）
print（Validation Bad）
callback（false）
}
}
case .Failure（_）：
callback（false）
}
}）
} // postBinaryToGdriveSimple
我不知道有没有关于Alamofire创建Google Drive不喜欢的多部分请求的方式。从谷歌的API网站，似乎是一个请求需要有Alamofire可能不会创建的某些参数，如内容长度和边界设置...
POST / upload / drive / v3 / files？uploadType = multipart HTTP / 1.1
主机：www.googleapis.com
授权：持票人your_auth_token
Content-Type ：多部分/相关; boundary = foo_bar_baz
Content-Length：number_of_bytes_in_entire_request_body
--foo_bar_baz
Content-Type：application / json; charset = UTF-8
{
name：我的文件
}
--foo_bar_baz
内容类型： image / jpeg
JPEG数据
--foo_bar_baz--
如果是这样，那么解决方法是什么？
仔细检查Google Drive的API文档。 b
$ b
看起来参数的关键字段是name（而不是title）。
如果需要额外的，自定义文件属性，限于单个应用程序，向json添加一个appProperties：
$ b
appProperties：{
title：whatever
}
I am trying to upload a file + parameters to Google Drive via Swift 2/Alamofire. In the code below, i I change the line that says:
"https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart"
to the following:
"https://www.googleapis.com/upload/drive/v3/files"
the file uploads to google without a name. Otherwise, the file upload fails with the same generic code:
Error Domain=com.alamofire.error Code=-6003 "Response status code was unacceptable: 400" UserInfo={NSLocalizedFailureReason=Response status code was unacceptable: 400}
I'd like to be able to upload the file with name and potentially other parameters as well. I know I'm mangling the multipart upload somehow, but I don't know what I'm doing wrong.
func postBinaryToGdriveSimple (token: String, callback: Bool -> Void){
var returnedId : String!
let path = NSBundle.mainBundle().pathForResource("drawing", ofType: "bin")
let bindata: NSData = NSData(contentsOfURL: NSURL(fileURLWithPath: path!))!
let parameters : [String: String] = ["title":"SomeFileName"]
let headers = ["Authorization": "Bearer \(token)"]
upload(
.POST,
"https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart",
headers: headers,
multipartFormData: { multipartFormData in
// append file parameters to request
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
// append binary file to request
multipartFormData.appendBodyPart(data: bindata, name: "upload", fileName: "drawing.bin", mimeType: "application/octet-stream")
},
encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.progress { bytesWritten, totalBytesWritten, totalBytesExpectedToWrite in
dispatch_async(dispatch_get_main_queue()) {
let percent = (Float(totalBytesWritten) / Float(totalBytesExpectedToWrite))
//progress(percent: percent)
print ("................\(percent)")
}
}
upload.validate()
upload.responseJSON { response in
switch response.result {
case .Success(let data):
print(response)
print("Validation Successful")
let json = JSON(data)
returnedId = json[("id")].stringValue
print("......id for uploaded file is \(returnedId)")
callback(true)
case .Failure(let error):
print(error)
print("Validation Bad")
callback(false)
}
}
case .Failure(_):
callback(false)
}
})
} // end of postBinaryToGdriveSimple
I wonder if there is something about the way Alamofire creates the multipart request that Google Drive is not liking. From the google api site, it seems like a request needs to have certain parameters that Alamofire may not be creating, such as Content-length and boundary settings...
POST /upload/drive/v3/files?uploadType=multipart HTTP/1.1
Host: www.googleapis.com
Authorization: Bearer your_auth_token
Content-Type: multipart/related; boundary=foo_bar_baz
Content-Length: number_of_bytes_in_entire_request_body
--foo_bar_baz
Content-Type: application/json; charset=UTF-8
{
"name": "My File"
}
--foo_bar_baz
Content-Type: image/jpeg
JPEG data
--foo_bar_baz--
If so, what is the work-around?
Double check the API documentation for Google Drive.
It appears that the key field for the parameter is "name" (not "title").
If you want additional, custom file properties, restricted to the single app, add an "appProperties" to the json:
"appProperties": { "title": "whatever" }
