利用hrpose rpc 连接传输以组合好的数据生成文件

php 项目中引用
在你的 composer 项目中的 composer.json 文件中，添加这部分：
{
"require": {
"hprose/hprose": ">=2.0.0"
}
}
使用
$header = ['aaa','cccc','dddd'];
$data = [['a1','c1','d1'],['a2','c2','d2'],['a2','c2','d2']];
$client = new \Hprose\Http\Client(env('excel_rpc', 'http://192.168.0.230:8881/rpc'), false);//同步执行
$b_str = json_encode(array_merge([$header], $data));
$path_str = "dc_" . $type . '_' . $this->lang . date('Ymd-His') . '.xlsx';
$return_data = json_decode($client->excel($b_str, $path_str), true);
Array
(
[code] => 0
[data] => dc_test20190428-124612.xlsx
[msg] => 生成完毕共花费0秒public/excel/dc_test20190428-124612.xlsx
)

go 部分 go 1.11+ 使用 go.mod 版本
go 环境自己搭建
go mod download
