swift Alamofire上传

 func testFileUpload() {
        
        let url = "http://192.168.0.15:8080/dcfdServer/device/springUpload.json"
        let imageData = UIImagePNGRepresentation(self.image)
        
        Alamofire.upload(multipartFormData: { (multipartFormData) in
//传递多个图片，多次添加即可
            multipartFormData.append(imageData!, withName: "12.png", fileName: "image", mimeType: "image/png")
            let strData = String("str")?.data(using: String.Encoding.utf8)
            //传递参数
            multipartFormData.append(strData!, withName: "str")
        }, to: url) { (result) in
            switch result {
            case .success(request: let request, streamingFromDisk: true, streamFileURL: nil):
                request.responseString(completionHandler: { (response) in
                    debugPrint(response)
                })
            case .failure(let error):
                debugPrint(error)
            default: break
            }

OC上传：

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];

    NSString *url = @"http://192.168.0.15:8080/dcfdServer/device/springUpload.json";
    [manager POST:url parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
        
        for (int i = 0; i < images.count ; i++) {
            UIImage *image = images[i];
            NSData *data = UIImagePNGRepresentation(image);
            [formData appendPartWithFileData:data name:[NSString stringWithFormat:@"%d.png",i] fileName:[NSString stringWithFormat:@"fileName%d.png",i] mimeType:@"image/png"];
            
        }
        
    } progress:^(NSProgress * _Nonnull uploadProgress) {
        NSLog(@"------%f",1.0 * uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
