Question

我要使用上传一个简单文件，

pod 'Alamofire', '~> 5.0.0-rc.3'

但是我在Linux主机的文件夹中看不到该文件。

upload.php文件：

<?php
   if(isset($_FILES['image'])){
      $errors= array();
      $file_name = $_FILES['image']['name'];
      $file_size =$_FILES['image']['size'];
      $file_tmp =$_FILES['image']['tmp_name'];
      $file_type=$_FILES['image']['type'];
      $file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));

      $extensions= array("jpeg","jpg","png");

      if(in_array($file_ext,$extensions)===false){
         $errors[]="extension not allowed, please choose a JPEG or PNG file.";
      }

      if($file_size > 2097152){
         $errors[]='File size must be excately 2 MB';
      }

      if(empty($errors)==true){
         move_uploaded_file($file_tmp,"images/".$file_name);
         echo "Success";
      }else{
         print_r($errors);
      }
   }
?>

快速文件：

    func upload(image: UIImage,
                progressCompletion: @escaping (_ percent: Float) -> Void,
                completion: @escaping (_ result: Bool) -> Void) {
        guard let imageData = image.jpegData(compressionQuality: 0.5) else {
        print("Could not get JPEG representation of UIImage")
        return
      }

      AF.upload(
        multipartFormData: { multipartFormData in
          multipartFormData.append(imageData,
                                   withName: "imagefile",
                                   fileName: "image.jpg",
                                   mimeType: "image/jpeg")
        },
        to: "http://website.com/upload.php", usingThreshold: UInt64.init(), method: .post)

        .uploadProgress { progress in
             progressCompletion(Float(progress.fractionCompleted))
        }
        .response { response in
            debugPrint(response)
        }

    }

    @IBAction func getStartedBtnClicked(_ sender: Any) {

        upload(
            image: UIImage(named: "uploadFile.png")!,
          progressCompletion: { [weak self] percent in
            guard let _ = self else {
              return
            }
            print("Status: \(percent)")
          },
          completion: { [weak self] result in
            guard let _ = self else {
              return
            }
        })
    }

在Swift代码中用于：“ https://httpbin.org/post”区域时：

Status: 1.0
...
[Data]: 19034 bytes
[Network Duration]: 0.9285140037536621s
[Serialization Duration]: 0.0s
[Result]: success(Optional(19034 bytes))

对于我的自定义网站的upload.php，结果为：

Status: 1.0
...
[Data]: None
[Network Duration]: 0.3820209503173828s
[Serialization Duration]: 0.0s
[Result]: success(nil)

Alamofire中最简单的代码段：

        if let fileURL = Bundle.main.url(forResource: "uploadFile", withExtension: "png") {
            AF.upload(fileURL, to: "http://website.com/upload.php").responseJSON { response in
                debugPrint(response)
            }
        }

我收到inputDataNilOrZeroLength错误：

[Request Body]: 
None
[Response]: 
[Status Code]: 200
[Headers]:

[Serialization Duration]: 0.0014129877090454102s
[Result]: failure(Alamofire.AFError.responseSerializationFailed(reason: Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength))

在upload.php的顶部，可通过以下页面在网络上运行：

<?php
   if(isset($_FILES['image'])){
      $errors= array();
      $file_name = $_FILES['image']['name'];
      $file_size =$_FILES['image']['size'];
      $file_tmp =$_FILES['image']['tmp_name'];
      $file_type=$_FILES['image']['type'];
      $file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));

      $extensions= array("jpeg","jpg","png");

      if(in_array($file_ext,$extensions)=== false){
         $errors[]="extension not allowed, please choose a JPEG or PNG file.";
      }

      if($file_size > 2097152){
         $errors[]='File size must be excately 2 MB';
      }

      if(empty($errors)==true){
         move_uploaded_file($file_tmp,"images/".$file_name);
         echo "Success";
      }else{
         print_r($errors);
      }
   }
?>
<html>
   <body>

      <form action="" method="POST" enctype="multipart/form-data">
         <input type="file" name="image" />
         <input type="submit"/>
      </form>

   </body>
</html>

即使是简单的文件上传，我也找不到方法。我想念的是什么？有人解释会很好。

稍后，我也应该配置它以上传视频文件。有任何配置建议吗？

您在服务器中查找的文件名是import React from 'react' import App from './App' export default class AppContainer extends React.Component { constructor(props) { super(props) this.state = { quantity: 0 } } handleQuantityChange = (e) => { if(e.type === 'blur' || e.key === 'Enter'){ const quantityWithRemovedLeadingZeroes = e.target.value != '' ? parseFloat(e.target.value) : 0 const tempNumberToChange = quantityWithRemovedLeadingZeroes === 0 ? 1 : 0 this.setState({ quantity: tempNumberToChange }, () => { this.setState({ quantity: quantityWithRemovedLeadingZeroes }) }) } else if(e.type==='change') { const newQuantity = e.target.value != '' ? parseFloat(e.target.value) : null this.setState({ quantity: newQuantity }) } } render() { return( <App Quantity={ this.state.quantity } HandleQuantityChange={this.handleQuantityChange} /> ) } }，并且随请求发送的文件名是$_FILES['image']。尝试按如下所示更改imagefile附加的内容

multipartFormData

使用Alamofire Swift 5上传文件问题？
