AFN以header、body传参方式请求服务器

需求：
指定参数放到header和body

NSMutableDictionary *params = [NSMutableDictionary dictionary];
[params setObject:@"" forKey:@"token"];
[params setObject:@"" forKey:@"reqid"];

NSString *url = @"";
NSMutableDictionary *parameterDict = [NSMutableDictionary dictionaryWithDictionary:params];

        [parameterToken setObject:parameterDict[@"token"] forKey:@"token"];
        [parameterDict removeObjectForKey:@"token"];
    }
    
//参数转成二进制

    manager.responseSerializer = responseSerializer;

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:url parameters:nil error:nil];
request.timeoutInterval = 60.f;
//请求头
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:ReturnValidString(params[@"token"]) forHTTPHeaderField:@"token"];
//请求体
[request setHTTPBody:dataBody];

NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromData:nil progress:^(NSProgress * _Nonnull uploadProgress) {
        // 计算进度
        float progress = (float)uploadProgress.totalUnitCount / uploadProgress.completedUnitCount;
        NSLog(@"上传进度:%.f",progress);

            NSLog(@"结果：%@",jsonData);
            //resultCode = 0000表示已请求成功

                failure(error);
            }
        }
    }];
    [uploadTask resume];

/// NSDictionary 转化为 NSString
- (NSString*)convertToJSONData:(id)infoDict {

    //如果您不关心生成的字符串的可读性，则传递 0 (options:0)

    jsonString = [jsonString stringByReplacingOccurrencesOfString:@" " withString:@""];// 去掉空格
