如何使用Swift将图像发送到php文件 [英] How to send a image to a php file using Swift

问题描述

对于我的应用程序，我需要将图像发送到php文件。
我已经知道如何使用这个发送字符串：

For my app i need to send a image to a php file. I already know how to send strings using this:

var bodyData = "info=test"

let URL: NSURL = NSURL(string: "LINK TO A PHP FILE")
let request:NSMutableURLRequest = NSMutableURLRequest(URL:URL)
request.HTTPMethod = "POST"
request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding);
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue())
{
    (response, data, error) in
    println(NSString(data: data, encoding: NSUTF8StringEncoding))
}

在我的php文件中：

$info = $_POST['info'];

echo $info;

但我不知道如何发送图片

But i don't know how to send a image

推荐答案

var imageData :NSData = UIImageJPEGRepresentation(imagenReduced, 1.0);       
var request: NSMutableURLRequest?
let HTTPMethod: String = "POST"
var timeoutInterval: NSTimeInterval = 60
var HTTPShouldHandleCookies: Bool = false

request = NSMutableURLRequest(URL: url)
request!.HTTPMethod = HTTPMethod
request!.timeoutInterval = timeoutInterval
request!.HTTPShouldHandleCookies = HTTPShouldHandleCookies


let boundary = "----------SwIfTeRhTtPrEqUeStBoUnDaRy"
let contentType = "multipart/form-data; boundary=\(boundary)"
request!.setValue(contentType, forHTTPHeaderField:"Content-Type")
var body = NSMutableData();


 let tempData = NSMutableData()
 let fileName = filenames + ".jpg" //"prueba.jpg"
 let parameterName = "userfile"


let mimeType = "application/octet-stream"

tempData.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
let fileNameContentDisposition = fileName != nil ? "filename=\"\(fileName)\"" : ""
let contentDisposition = "Content-Disposition: form-data; name=\"\(parameterName)\"; \(fileNameContentDisposition)\r\n"
tempData.appendData(contentDisposition.dataUsingEncoding(NSUTF8StringEncoding)!)
tempData.appendData("Content-Type: \(mimeType)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
tempData.appendData(imageData)
tempData.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

body.appendData(tempData)

body.appendData("\r\n--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

request!.setValue("\(body.length)", forHTTPHeaderField: "Content-Length")
request!.HTTPBody = body



var vl_error :NSErrorPointer = nil
var responseData  = NSURLConnection.sendSynchronousRequest(request,returningResponse: nil, error:vl_error)

var results = NSString(data:responseData, encoding:NSUTF8StringEncoding)
println("finish \(results)")
