AFNetworking 文件上传Data,File图片，文件等上传

一：AFNetworking的文件上传：

主要几个以下类似

- (BOOL)appendPartWithFileURL:(NSURL *)fileURL
                         name:(NSString *)name
                        error:(NSError * __autoreleasing *)error;

二：主要代码：

    //配置文件上传
    
    //图片data 上传
    //UIImage *upImage = [UIImage imageNamed:@"testImage.png"];
    //NSData *imageData = UIImagePNGRepresentation(upImage);
    
    //文件file上传，上传mp3音乐文件 
    //NSString *theUpFilePath = [NSString stringWithFormat:@"%@testMusic.mp3",NSTemporaryDirectory()];
    
    //上传个图片文件；
    NSString *theImagePath = [[NSBundle mainBundle] pathForResource:@"testImage" ofType:@"png"];
    
    self.uploadFileClient = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:kCOCOA_FileUPload]];
    NSMutableURLRequest *fileUpRequest = [_uploadFileClient multipartFormRequestWithMethod:@"POST" path:@"" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        
        //[formData appendPartWithFileData:imageData name:@"file" fileName:@"testImage" mimeType:@"image/png"];
        
        //[formData appendPartWithFileURL:[NSURL fileURLWithPath:theUpFilePath isDirectory:NO] name:@"file" fileName:@"testMusic.mp3" mimeType:@"audio/mpeg3" error:nil];
        
        [formData appendPartWithFileURL:[NSURL fileURLWithPath:theImagePath] name:@"file" error:nil];
        
    }];
    
    self.fileUploadOp = [[AFHTTPRequestOperation alloc]initWithRequest:fileUpRequest];

三：文件上传Demo

 1 #pragma mark 文件上传;
 2     
 3     //文件的 mine_type http://www.iana.org/assignments/media-types/media-types.xhtml
 4     
 5     UIProgressView *uploadFileProgressView = [[UIProgressView alloc]initWithProgressViewStyle:UIProgressViewStyleDefault];
 6     uploadFileProgressView.center = CGPointMake(self.view.center.x, 100);
 7     uploadFileProgressView.progress = 0;
 8     uploadFileProgressView.progressTintColor = [UIColor blueColor];
 9     uploadFileProgressView.trackTintColor = [UIColor grayColor];
10     [self.view addSubview:uploadFileProgressView];
11     
12     
13     //开始
14     UIButton *startUp = [UIButton buttonWithType:UIButtonTypeRoundedRect];
15     startUp.frame = CGRectMake(80, 120, 150, 30);
16     [startUp setTitle:@"开始上传" forState:UIControlStateNormal];
17     [startUp addTarget:self action:@selector(startUploadOP) forControlEvents:UIControlEventTouchUpInside];
18     
19     
20     [self.view addSubview:startUp];
21 
22     
23     //配置文件上传
24     
25     //图片data 上传
26     //UIImage *upImage = [UIImage imageNamed:@"testImage.png"];
27     //NSData *imageData = UIImagePNGRepresentation(upImage);
28     
29     //文件file上传，上传mp3音乐文件 
30     //NSString *theUpFilePath = [NSString stringWithFormat:@"%@testMusic.mp3",NSTemporaryDirectory()];
31     
32     //上传个图片文件；
33     NSString *theImagePath = [[NSBundle mainBundle] pathForResource:@"testImage" ofType:@"png"];
34     
35     self.uploadFileClient = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:kCOCOA_FileUPload]];
36     NSMutableURLRequest *fileUpRequest = [_uploadFileClient multipartFormRequestWithMethod:@"POST" path:@"" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
37         
38         //[formData appendPartWithFileData:imageData name:@"file" fileName:@"testImage" mimeType:@"image/png"];
39         
40         //[formData appendPartWithFileURL:[NSURL fileURLWithPath:theUpFilePath isDirectory:NO] name:@"file" fileName:@"testMusic.mp3" mimeType:@"audio/mpeg3" error:nil];
41         
42         [formData appendPartWithFileURL:[NSURL fileURLWithPath:theImagePath] name:@"file" error:nil];
43         
44     }];
45     
46     self.fileUploadOp = [[AFHTTPRequestOperation alloc]initWithRequest:fileUpRequest];
47     
48     [_fileUploadOp setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
49         startUp.enabled = NO;
50         [startUp setTitle:@"正在上传" forState:UIControlStateNormal];
51         CGFloat progress = ((float)totalBytesWritten) / totalBytesExpectedToWrite;
52         [uploadFileProgressView setProgress:progress animated:YES];
53         
54     }];
55     
56     [_fileUploadOp setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
57         startUp.enabled = NO;
58         [startUp setTitle:@"完成" forState:UIControlStateNormal];
59         NSLog(@"upload finish ---%@",[[NSString alloc]initWithData:responseObject encoding:NSUTF8StringEncoding]);
60         
61     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
62         NSLog(@"error %@",error);
63     }];
64     
65     
66     
67     
68     
69     
70     
71 }
72 
73 #pragma mark AFNetworking 文件上传
74 
75 - (void)startUploadOP
76 {
77     [_fileUploadOp start];
78 }

四：关于文件上传服务器，建议使用php,在 windows 上下载个 wamp 一键就配置成了php 服务器
