swift文件上传及表单提交

var carData:NSMutableDictionary = NSMutableDictionary();

var request:NSMutableURLRequest = NSMutableURLRequest();

request.URL = NSURL(string: "YOUR URL ADDR");

request.HTTPMethod = "POST";

request.timeoutInterval = 10;

var body:NSMutableData = NSMutableData();

//设置表单分隔符

var boundary:NSString = "----------------------1465789351321346";

var contentType = NSString(format: "multipart/form-data;boundary=%@", boundary);

request.addValue(contentType, forHTTPHeaderField: "Content-Type");

//写入Info内容

var keys:NSArray = carData.allKeys;

for key in keys{

    body.appendData(NSString(format: "--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!);

    body.appendData(NSString(format: "Content-Disposition:form-data;name=\"%@\"\r\n\r\n", key as NSString).dataUsingEncoding(NSUTF8StringEncoding)!);

//如果有中文进行UTF8编码
body.appendData("\(carData.objectForKey(key) as String)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

}

//写入图片内容

body.appendData("Content-Type:image/jpeg\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

body.appendData(imageData);

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

//写入尾部

body.appendData(NSString(format: "--%@--\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!);

request.HTTPBody = body;

var urlResponse:NSHTTPURLResponse? = nil;

var error:NSError? = NSError();

//第三方判断网络是否连接

if IJReachability.isConnectedToNetwork() {

    NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue()) { (response, data, error) -> Void in

if(error == nil){

    var json:NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary;

    dispatch_async(dispatch_get_main_queue(), {
