AFHTTPRequestOperationManager实现在任意格式数据下载，网上查找只有上传，下载图片的资料。

1、上传示例

AFHTTPRequestOperationManager *requestManager = [[AFHTTPRequestOperationManager alloc] init];    requestManager.responseSerializer = [AFJSONResponseSerializer serializer];        [requestManager POST:@"http://192.168.165.68:8080/xxxxx/fileController/upload.action" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {                NSData *data = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"时钟.zip" ofType:nil]];                NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];        [dictionary setObject:@"multipart/form-data" forKey:@"Content-Type"];        [dictionary setObject:[NSNumber numberWithInteger:data.length] forKey:@"Content-Length"];        [dictionary setObject:@"form-data; name=\"f2\"; filename=\"时钟.zip\"" forKey:@"Content-Disposition"];            [formData appendPartWithHeaders:dictionary body:data];    } success:^(AFHTTPRequestOperation *operation, id responseObject) {                //  服务器返回JSON的数据        NSLog(@"content = %@", [responseObject objectForKey:@"content"]);            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"error = %@", error);    }];

根据实际情况进行修改，服务器返回数据的时候，需设置response的ContentType设置为"text/json;charset=UTF-8。否则success块将不会被调用。

2、下载示例

    AFHTTPRequestOperationManager *requestManager = [[AFHTTPRequestOperationManager alloc] init];    requestManager.responseSerializer = [AFHTTPResponseSerializer serializer];        [requestManager POST:@"http://192.168.165.68:8080/xxxx/fileController/download.action" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {                NSDictionary *headers = operation.response.allHeaderFields;                // 解析下载文件名        NSString *content = [headers objectForKey:@"Content-Disposition"];        NSString *fileName = [[content componentsSeparatedByString:@"="] lastObject];                // 保存文件        NSString *destPath = [NSString stringWithFormat:@"%@/tmp/%@", NSHomeDirectory(), [fileName lastPathComponent]];        [operation.responseData writeToFile:destPath atomically:YES];            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"error = %@", error);    }];
