【问题描述】：

我想用 almofire 将照片上传到服务器我现在正在使用此代码，但我正在超时

let imageData = UIImageJPEGRepresentation(croppedImage, 1)

let urlRequest = self.urlRequestWithComponents(url, imageData: imageData!)
self.alamofire.upload(urlRequest.1, to: urlRequest.0 as! URLConvertible).responseJSON  response in
    guard response.result.isSuccess else 
        self.showError()
        return
    

    guard let data = response.result.value else 
        self.showError()
        return
    

    let json = JSON(data)


func urlRequestWithComponents(_ urlString:String, imageData:Data) -> (URLRequestConvertible, Data) 
    var urlRequest = URLRequest(url: URL(string: urlString)!)
    urlRequest.httpMethod = HTTPMethod.post.rawValue
    let boundary = generateBoundaryString()
    let contentType = "multipart/form-data;boundary=" + boundary
    urlRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")

    let uploadData = NSMutableData()

    uploadData.append("\r\n--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
    uploadData.append("Content-Disposition: form-data; name=\"file\"; filename=\"file.png\"\r\n".data(using: String.Encoding.utf8)!)
    uploadData.append("Content-Type: image/png\r\n\r\n".data(using: String.Encoding.utf8)!)
    uploadData.append(imageData)
    uploadData.append("\r\n--\(boundary)--\r\n".data(using: String.Encoding.utf8)!)

    return try! (Alamofire.URLEncoding.default.encode(urlRequest, with: nil), uploadData as Data)

这个问题有解决办法吗？

请回复我的回答。

【参考方案1】：

在 swift 3 中试试这个

Alamofire.upload(multipartFormData:  (multipartFormData) in
    multipartFormData.append(imageData, withName: "photo_path", fileName: "swift_file.jpeg", mimeType: "image/jpeg")
    , to:"http://server1/upload_img.php")
 (result) in
    switch result 
    case .success(let upload, _, _):

        upload.uploadProgress(closure:  (Progress) in
            print("Upload Progress: \(Progress.fractionCompleted)")
        )

        upload.responseJSON  response in
            //self.delegate?.showSuccessAlert()
            print(response.request)  // original URL request
            print(response.response) // URL response
            print(response.data)     // server data
            print(response.result)   // result of response serialization
            //                        self.showSuccesAlert()
            //self.removeImage("frame", fileExtension: "txt")
            if let JSON = response.result.value 
                print("JSON: \(JSON)")
            
        

    case .failure(let encodingError):
        //self.delegate?.showFailAlert()
        print(encodingError)
    

【讨论】：

"server1/upload_img.php"是你的图片位置路径还是API函数文件路径？？

@Bhavin_m 不是我的 API URL
