AFNetworking图片上传

//上传图片
-(void)upLoadImage:(UIImage *)upImage
{
    //创建管理
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    //存放非文件参数
    NSMutableDictionary *params = [NSMutableDictionary dictionary];
    [params setObject:@"qwe" forKey:@"userName"];
    //发送请求
    [manager POST:@"http://192.168.1.27:9000/os/ks/add" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

//        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
//        formatter.dateFormat = @"yyyyMMddHHmmss";
//        NSString *str = [formatter stringFromDate:[NSDate date]];
//        NSString *fileName = [NSString stringWithFormat:@"%@.jpg", str];
    
        NSData *fileData = UIImageJPEGRepresentation(upImage, 1.0);
        
        [formData appendPartWithFileData:fileData name:@"headFile" fileName:self.imageName mimeType:@"image/jpeg"];
    
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        
        NSLog(@"上传成功");
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"上传失败 ");
    }];
   
}

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

 [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；
