英文:
Convert Redigo Pipeline result to strings
问题
我成功地将多个HGETALL命令进行了流水线处理，但是我无法将它们转换为字符串。
我的示例代码如下：
// 在端口6379上初始化Redis（Redigo）客户端// 并使用默认地址127.0.0.1/localhostclient, err := redis.Dial("tcp", ":6379")if err != nil {panic(err)}defer client.Close()// 初始化流水线client.Send("MULTI")// Send将命令写入连接的输出缓冲区client.Send("HGETALL", "post:1") // 其中"post:1"包含"title 'hi'"client.Send("HGETALL", "post:2") // 其中"post:1"包含"title 'hello'"// 执行流水线pipe_prox, err := client.Do("EXEC")if err != nil {panic(err)}log.Println(pipe_prox)
只要您能够接受非字符串的结果，这样就可以了。我得到的结果是：
[[[116 105 116 108 101] [104 105]] [[116 105 116 108 101] [104 101 108 108 111]]]
但是我需要的是：
"title" "hi" "title" "hello"
我尝试了以下方法和其他组合：
result, _ := redis.Strings(pipe_prox, err)log.Println(pipe_prox)
但是我得到的只是：[]
我应该注意到，它可以处理多个HGET key value命令，但这不是我需要的。
我做错了什么？我应该如何将这个"数字映射"转换为字符串？
感谢您的帮助。

I managed to Pipeline multiple HGETALL commands, but I can't manage to convert them to strings.
My sample code is this:
// Initialize Redis (Redigo) client on port 6379// and default address 127.0.0.1/localhostclient, err := redis.Dial("tcp", ":6379")if err != nil {panic(err)}defer client.Close()// Initialize Pipelineclient.Send("MULTI")// Send writes the command to the connection's output bufferclient.Send("HGETALL", "post:1") // Where "post:1" contains " title 'hi' "client.Send("HGETALL", "post:2") // Where "post:1" contains " title 'hello' "// Execute the Pipelinepipe_prox, err := client.Do("EXEC")if err != nil {panic(err)}log.Println(pipe_prox)
It is fine as long as you're comfortable showing non-string results.. What I'm getting is this:
[[[116 105 116 108 101] [104 105]] [[116 105 116 108 101] [104 101 108 108 111]]]
But what I need is:
"title" "hi" "title" "hello"
I've tried the following and other combinations as well:
result, _ := redis.Strings(pipe_prox, err)log.Println(pipe_prox)
But all I get is: []
I should note that it works with multiple HGET key value commands, but that's not what I need.
What am I doing wrong? How should I do it to convert the "numerical map" to strings?
Thanks for any help

每个HGETALL返回自己的一系列值，这些值需要转换为字符串，而管道返回的是这些值的一系列。首先使用通用的redis.Values来分解这个外部结构，然后可以解析内部的切片。
// 执行管道
pipe_prox, err := redis.Values(client.Do("EXEC"))
if err != nil {
panic(err)
}
for _, v := range pipe_prox {
s, err := redis.Strings(v, nil)
if err != nil {
fmt.Println("不是批量字符串响应", err)
}
fmt.Println(s)
}
输出：
[title hi][title hello]
英文:
Each HGETALL returns it's own series of values, which need to be converted to strings, and the pipeline is returning a series of those. Use the generic redis.Values to break down this outer structure first then you can parse the inner slices.
// Execute the Pipelinepipe_prox, err := redis.Values(client.Do("EXEC"))if err != nil {panic(err)}for _, v := range pipe_prox {s, err := redis.Strings(v, nil)if err != nil {fmt.Println("Not a bulk strings repsonse", err)}fmt.Println(s)}
prints:
[title hi][title hello]

你可以这样做：
pipe_prox, err := redis.Values(client.Do("EXEC"))for _, v := range pipe_prox.([]interface{}) {fmt.Println(v)}
你可以像这样执行。
英文:
you can do it like this:
pipe_prox, err := redis.Values(client.Do("EXEC"))for _, v := range pipe_prox.([]interface{}) {fmt.Println(v)}
