 5     AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
 6     //存放非文件参数
 7     NSMutableDictionary *params = [NSMutableDictionary dictionary];
 8     [params setObject:@"qwe" forKey:@"userName"];
 9     //发送请求
10     [manager POST:@"http://192.168.1.27:9000/os/ks/add" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

12 //        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
13 //        formatter.dateFormat = @"yyyyMMddHHmmss";
14 //        NSString *str = [formatter stringFromDate:[NSDate date]];
15 //        NSString *fileName = [NSString stringWithFormat:@"%@.jpg", str];
16     
17         NSData *fileData = UIImageJPEGRepresentation(upImage, 1.0);
18         
19         [formData appendPartWithFileData:fileData name:@"headFile" fileName:self.imageName mimeType:@"image/jpeg"];
20     
21     } success:^(AFHTTPRequestOperation *operation, id responSEObject) {
22         
23         NSLog(@"上传成功");
24     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
25         NSLog(@"上传失败 ");
26     }];
27    
28 }

不过需要主要的是：

不要用下面的这个方法来设置文件参数

1  [formData appendPartWithFormData:fileData name:self.imageName];

这个方法在上传图片的时候会有问题，用上面的方法就好了；

还有，在发送请求之前要判断方法内参数image是否为nil；
