我正在调用一个api，并传递一些参数，包括从icloud获取一些文件，如pdf、doc、docx并调用该api。
现在我正在从icloud中挑选一些文件，需要传递给api调用。问题是我的选择文件(pdf或doc(没有转换为nsdata，字节数为0。所以它没有返回到我的身体参数。帮助我找出哪里做了错误的
我的代码：
func uploadthefileToserver(){
if let url = URL(string: "https://www.exampleurl/api"){
var request = URLRequest(url: url)
let boundary:String = "Boundary-(UUID().uuidString)"
// let request = NSMutableURLRequest(url:myUrl! as URL);
request.httpMethod = "POST"
request.timeoutInterval = 10
request.setValue("multipart/form-data; boundary=(boundary)", forHTTPHeaderField: "Content-Type")
let postJobData:[String:Any] = ["UserId":"107","name":"hardcodevalue"]
var dataFile: Data = Data()
print(fullDestPath) ///Users/sathish/Library/Developer/CoreSimulator/Devices/4464E7A8-0F38-4802-B645-19721D251054/data/Containers/Data/Application/714B1B8E-5872-42B9-B963-B0C51C9403D7/Documents/NewFileiCloud/iOS.DOCX"
do{
dataFile = try NSData.init(contentsOf: URL(fileURLWithPath: fullDestPath, isDirectory: true)) as Data
print(dataFile)
}catch{
print(error)
}
if(dataFile==nil) { return; }
print(dataFile) //0 bytes
request.httpBody = createBodyWithParameters(parameters: postJobData, filePathKey: "Resume", FileData: dataFile as NSData , boundary: boundary) as Data
print(postJobData)
print(dataFile)
let task = URLSession.shared.dataTask(with: request as URLRequest) {
data, response, error in
if error != nil {
print("error=(error)")
return
}else if let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue){
print("****** response data = (responseString)")
do {
let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary
print(json)
let status = json!["Success"] as! String
let errMessage = json!["Message"] as? String
DispatchQueue.main.async() {
if status == "1"{
print(errMessage)
}else{
print(errMessage)
}
}
}catch{
print(error)
}
}
}; task.resume()
}
}
不确定我哪里做错了。我放了一些打印函数作为参考。
主要部件：
dataFile = try NSData.init(contentsOf: URL(fileURLWithPath:
fullDestPath, isDirectory: true)) as Data
request.httpBody = createBodyWithParameters(parameters: postJobData,
filePathKey: "Resume", FileData: dataFile as NSData , boundary:
boundary) as Data
感谢
更新：

for urll in filePathUrl{
filepath = filePathUrl[0] as! URL
print(filepath)
filePathString = filepath.path
urlstr = NSURL(fileURLWithPath: filePathString).lastPathComponent!
print(urlstr)

您正在尝试这样做，
-
将PDFURL转换为数据
-
将数据转换为.PDF
-
将该.PDF存储在Doc.Dir.中
-
正在从Doc.Dir检索.PDF并传递到服务器。
对于上述任务，您必须在Doc.Dir中创建文件夹NewFileiCloud。然后，将pdfUrl转换为data，并将数据写入.pdf文件，然后，从doc.dir获得.pdf路径，将其转换为Data并传递给server。
我已经为你做了样品。这会让你满意的。
override func viewDidAppear(_ animated: Bool) {
// I have did sample for you by taking .pdf from bundle.
if let pathPDF = Bundle.main.path(forResource: "sample", ofType: "pdf") {
let path = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
let documentDirectoryPath:String = path[0]
let fileManager = FileManager()
var destinationURLForFile = URL(fileURLWithPath: documentDirectoryPath.appending("/NewFileiCloud"))
do {
//You have to create directory with above name.
try fileManager.createDirectory(at: destinationURLForFile, withIntermediateDirectories: true, attributes: nil)
destinationURLForFile.appendPathComponent("reader.pdf")
//YOUR PDF URL [pathPDF [my bundle path, you have to give your URL]] to DATA
let pdfData = try Data(contentsOf: URL(fileURLWithPath: pathPDF))
// WRITE ITS CONTENT to Doc.Dir.
try pdfData.write(to: destinationURLForFile, options:.atomic)
//ASSIGN PATH TO GLOBAL URL VARIABLE
fullPAth = destinationURLForFile
print("conclude ", destinationURLForFile)
uploadToServer()
}
catch(let error){
print(error)
}
}
}
func uploadToServer() {
.....
do {
// Here you can get PDF contents as Data.
// With this Data, you can pass to Server Side.
let pdfPOSTData = try Data(contentsOf: fullPAth!)
}
catch let e{
print("Catch_Not_worlk ", e)
}
