在 Ruby 1.8.7 中将带有二进制数据的 YAML 响应转换为 UTF-8 [英] Converting a YAML response w/ binary data to UTF-8 in Ruby 1.8.7

问题描述

我正在从 API 中提取响应并接收:

I'm pulling a response from an API and receiving:

      response: 
        job: 
          unit_count: "1"
          slug: Answers
          lc_tgt: ja
          body_tgt: !binary |
            5Zue562U

          lc_src: en
          body_src: Answers
          job_id: "1948888"
      opstat: ok

body_tgt 值应该是几个日文字符(回答)，但为了安全运输，它们正在被转换.我在 1.8.7，所以我不能 force_encoding.有没有办法解包()它们?

That body_tgt value should be a couple Japanese characters(回答), but they are being converted for safe shipping. I'm in 1.8.7, so I can't force_encoding. Is there a way to unpack() them?

推荐答案

这似乎是一个 YAML 文档，而不是 JSON，使用 YAML 的二进制数据语言(反过来使用 base64 编码).

That appears to be a YAML document, not JSON, using YAML's binary data language (which in turn uses base64 encoding).

Ruby 内置的 YAML 解析库应该能够为您解析数据:

Ruby's built in YAML parsing library should be able to parse the data for you:

> x = YAML.load('      response: 
        job: 
          unit_count: "1"
          slug: Answers
          lc_tgt: ja
          body_tgt: !binary |
            5Zue562U

          lc_src: en
          body_src: Answers
          job_id: "1948888"
      opstat: ok')
 => {"opstat"=>"ok", "response"=>{"job"=>{"slug"=>"Answers", 
"unit_count"=>"1", "lc_tgt"=>"ja", "lc_src"=>"en", "body_tgt"=>"回答",
"job_id"=>"1948888", "body_src"=>"Answers"}}}

为了生成直接嵌入 UTF-8 的 YAML，而不是转义为二进制对象，您可以使用 ya2yaml，又一个 to_yaml"实现，它可以产生编码为 UTF-8 的输出.安装 ya2yaml gem，然后调用它:

In order to produce YAML with UTF-8 directly embedded, instead of escaped as binary objects, you can use ya2yaml, "yet another to_yaml" implementation, which can produce output encoded as UTF-8. Install the ya2yaml gem, and then invoke it as:

> require 'ya2yaml'
> x.ya2yaml(:syck_compatible => true)
