本文介绍了在AFNetworking 3.0+ 版本中如何设置HTTP请求头Header，特别是针对Content-Type为application/octet-stream;charset=utf-8的情况。由于AFHTTPRequestOperation在新版本中被废弃，取而代之的是AFHTTPSessionManager，作者详细说明了使用AFHTTPSessionManager进行Header配置的方法。

我项目里网络请求的Content-Type是application/octet-stream;charset=utf-8。
这种方式跟application/json的不一样，请求参数是二进制的数据流形式的，必须放到body里面去请求。所以问题来了，之前项目用的AFNetworking是2.5.+ 的，现在更新了AFNetworking到3.0+，发现之前的网络请求的AFHTTPRequestOperation被废弃了。现在用AFHTTPSessionManager代替了。不知道怎么设置Header？？

AFNetworking 2.0+ 设置请求头

 NSMutableURLRequest *jsonRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:request.stringOfApiURLString]];
 jsonRequest.HTTPMethod = @"POST";
 NSMutableData *postBody = [NSMutableData data];
 int msgid = request.msgid;
 NSData *dataMsgid = [NSData dataWithBytes:&msgid length: 4];   
 [postBody appendData:dataMsgid];
 AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:jsonRequest];
    [op.securityPolicy setAllowInvalidCertificates:YES];
    [op.securityPolicy setValidatesDomainName:NO];
    [op.securityPolicy setValidatesCertificateChain:NO];
    op.responseSerializer = [AFHTTPResponseSerializer serializer];
    [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObj){
     //处理数据
        }

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        if (failure) {
            failure(error);
            NSString *str = [[NSString alloc]initWithData:operation.responseObject encoding:NSUTF8StringEncoding];
            NSLog(@"--- request error   %@",str);
        }
    }];
    [[NSOperationQueue mainQueue] addOperation:op];

//处理你的数据

    }
}

NSLog(@"Error: %@, %@, %@", error, response, responseObject);
}
}] resume];
