Swift Alamofire上传heic格式问题

项目利用Alamofire上传文件，之前同事没注意考虑格式，造成图片上传不了问题。  
上传文件格式如下：

let mimeTypes = ["png": "image/png",
                                     "jpg": "image/jpg",
                                     "jpeg": "image/jpeg",
                                     "heic": "image/heic",
                                     "heif": "image/heif",
                                     "webp": "image/webp",
                                     "tif": "image/tif",
                                     "gif": "image/gif",
                                     "mp4": "video/mp4",
                                     "mov": "video/mov"]

刚开始后端同事不帮我们处理.heic格式的文件，那么就需要我们自己处理了，自己转一下格式再上传：  
代码如下：

//其他格式也是一样
    if  suffix == "heic" || suffix == "heif" {
                        guard let newFileName = fileName.components(separatedBy: ".").first else {
                            break
                        }
                        let file1Data = try! Data(contentsOf: filePathUrl)
                        if let image: UIImage = UIImage(data: file1Data as Data) {
                            let twoData = image.jpegData(compressionQuality : 1.0)! as NSData
                            let newFileName = newFileName + ".jpeg"
                            formData.append(twoData as Data, withName: "files", fileName: newFileName , mimeType: "image/jpeg")
                            print("打印一下heic的图片名称----\(newFileName)")
                        }
                    }else{
                        formData.append(filePathUrl, withName: "files", fileName: fileName, mimeType: fileMimeType)
                    }

完整代码：

Alamofire.upload(multipartFormData: { (formData: MultipartFormData) -> Void in
                for filePathUrl in paths {
    
                    guard let fileName = filePathUrl.absoluteString.components(separatedBy: "/").last,
                        let suffix = fileName.components(separatedBy: ".").last?.lowercased() else {
                        debugPrint("上传文件：获取文件名错误")
                        break
                    }
                    let mimeTypes = ["png": "image/png",
                                     "jpg": "image/jpg",
                                     "jpeg": "image/jpeg",
                                     "heic": "image/heic",
                                     "heif": "image/heif",
                                     "webp": "image/webp",
                                     "tif": "image/tif",
                                     "gif": "image/gif",
                                     "mp4": "video/mp4",
                                     "mov": "video/mov"]
                    guard let fileMimeType = mimeTypes[suffix] else {
                        self.log.error("上传文件：获取mimeType错误")
                        print("上传文件：获取mimeType错误")
                        break
                    }
                    print("打印一下heic的图片名称----\(fileName)")
                   // formData.append(filePathUrl, withName: "files", fileName: fileName, mimeType: fileMimeType)
                    if  suffix == "heic" || suffix == "heif" {
                        guard let newFileName = fileName.components(separatedBy: ".").first else {
                            break
                        }
                        let file1Data = try! Data(contentsOf: filePathUrl)
                        if let image: UIImage = UIImage(data: file1Data as Data) {
                            let twoData = image.jpegData(compressionQuality : 1.0)! as NSData
                            let newFileName = newFileName + ".jpeg"
                            formData.append(twoData as Data, withName: "files", fileName: newFileName , mimeType: "image/jpeg")
                            print("打印一下heic的图片名称----\(newFileName)")
                        }
                    }else{
                        formData.append(filePathUrl, withName: "files", fileName: fileName, mimeType: fileMimeType)
                    }
                }
    
                for (key, value) in body {
                    formData.append(value.data(using: .utf8)!, withName: key)
                }
    
            }, usingThreshold: 5, to: url, method: .post, headers: header, encodingCompletion: { result in
                switch result {
           }
            })

这样就能自己转格式上传文件了
