如何将图像文件从保存的 NSUserDefault 上传到 php 服务器？

Question

我想在我的应用程序中更改个人资料图片，并在编辑后将图片上传到 PHP 服务器。至此我将更改后的个人资料图片保存到本地。

我的问题是如何将更改后的图像上传到 PHP 服务器（上传图像文件）？我可以使用 AFNetworking 3.X 并且我需要为这种情况编写后端 API 吗？有什么方法可以直接上传图片文件到服务器吗？

到目前为止，这是我使用 UIImagePickerController 所做的，在此阶段之前它工作正常：-

-(void)changeProfileImage:(UITapGestureRecognizer *)recognizer{

    if (!_photoManager) {
        _photoManager =[[SelectPhotoManager alloc]init];
    }
    [_photoManager startSelectPhotoWithImageName:@"Select Profile Image"];
    __weak typeof(self)mySelf=self;
    //Select Photo
    _photoManager.successHandle=^(SelectPhotoManager *manager,UIImage *image){

        mySelf.imgProfileImage.image = image;
        NSData *data = UIImagePNGRepresentation(image);
        [[NSUserDefaults standardUserDefaults] setObject:data forKey:@"imgProfile"];
    };
}

请帮忙。谢谢。

    // HTTP method to upload file to web server
-(void)initWithURL:(NSString *)url image:(NSData *)imageData andFileName:(NSString *)filename delegate:(id)del {
    // your PHP server url
    // your image data
    NSString *urlString = url;
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];

    // if access token defined for authrization
    NSString *token = [NSString stringWithFormat:@"Bearer %@",[[[CommonUserDefault getUserInfo] objectForKey:@"token"] objectForKey:@"accessToken"]];
    [request addValue:token forHTTPHeaderField: @"Authorization"];

    NSMutableData *body = [NSMutableData data];

    NSString *boundary = @"---------------------------14737809831466499882746641449";
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
    [request addValue:contentType forHTTPHeaderField:@"Content-Type"];

    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"files\"; filename=\"%@.jpg\"\r\n",filename] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[NSData dataWithData:imageData]];
    [body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

        // close form
    [body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
        // set request body
    [request setHTTPBody:body];

        //return and test
    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

    id json = [NSJSONSerialization JSONObjectWithData:returnData options:0 error:nil];
     NSLog(@"json upload picture = %@",json);

    int statusCode = [[json objectForKey:@"statusCode"] intValue];
    if(statusCode == <errorCode>){
    }
}
