【问题描述】：

我想在 swift 中使用AFNetworking 将多张图片上传到我的网站，但只上传了array 中的最后一张图片。

swift 脚本：

let url = "http://pathtomysite"
        let afHTTP : AFHTTPRequestSerializer = AFHTTPRequestSerializer()
        let request: NSMutableURLRequest = afHTTP.multipartFormRequestWithMethod("POST", URLString: url, parameters: nil, constructingBodyWithBlock: {(formData: AFMultipartFormData) in
            var i = 0
             for image in upImage {
                 let imageData  : NSData = UIImageJPEGRepresentation(image as UIImage, 0.5)!
            formData.appendPartWithFileData(imageData, name: "uploaded_file", fileName: "imagex\(i)x.png", mimeType: "image/png")
            i++
            }
            }, error: nil)
        let managerS : AFURLSessionManager = AFURLSessionManager.init(sessionConfiguration: NSURLSessionConfiguration.defaultSessionConfiguration())
        let uploadTask = managerS.uploadTaskWithStreamedRequest(request, progress: nil) { (response, AnyObject, error) -> Void in
            if (error != nil){
                print("error")
            }
        }
        uploadTask.resume()

php 脚本：

<?php
$dt = date("Ymdhis");
$fileInfo = pathinfo($_FILES['uploaded_file']['name']);
$file_path = "uploads/";
$file_path = $file_path . basename($_FILES['uploaded_file']['name']);
if (move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {

     rename($file_path, 'uploads/' . $dt . '.' . $fileInfo['extension']);
} 

?>

【解决方案1】：

试试这个：

let url = "YOUR_URL"
let afHTTP : AFHTTPRequestSerializer = AFHTTPRequestSerializer()
let request: NSMutableURLRequest = afHTTP.multipartFormRequestWithMethod("POST", URLString: url, parameters: nil, constructingBodyWithBlock: {(formData: AFMultipartFormData) in
  for (index, image) in upImage.enumerate() {
    let imageData = UIImageJPEGRepresentation(image as UIImage, 0.5)!
    formData.appendPartWithFileData(imageData, name: "uploaded_file[]", fileName: "imagex\(index)x.png", mimeType: "image/png")
  }
  }, error: nil)
let managerS : AFURLSessionManager = AFURLSessionManager.init(sessionConfiguration: NSURLSessionConfiguration.defaultSessionConfiguration())
let uploadTask = managerS.uploadTaskWithStreamedRequest(request, progress: nil) { (response, AnyObject, error) -> Void in
  if (error != nil){
    print("error")
  }
}
uploadTask.resume()

并将您的脚本更改为以下内容：

foreach ($_FILES["uploaded_file"]["tmp_name"] as $index => $tmp_name) {
    $filePath = "uploads/" . basename($_FILES["uploaded_file"]["name"][$index]);
    if (move_uploaded_file($tmp_name, $filePath)) {
        // rename like you want to
    }
}

重要的是在上传代码中的 uploaded_file[] 中添加括号。如果您不包含 []，则每张图片上传都会覆盖最后一张。

另一个重要的部分是脚本中的 foreach 循环，它处理多个上传的图像，而不仅仅是一个。
