使用 Bash 脚本循环遍历多个 cURL api 请求正文参数

Question

我想使用 Google Cloud 的语音识别 API 将多个音频文件转换为文本。

我成功转录了一个名为“1.flac”的音频文件...

要求：

curl -s -H "Content-Type: application/json" \
-H "Authorization: Bearer ACCESSTOKEN" \
https://speech.googleapis.com/v1/speech:recognize \
-d '
{"config": {"languageCode": "pt-BR", "audioChannelCount": 2},"audio":{"uri": "gs://PROJECTID/1.flac"}}
'

响应：

{
  "results": [
    {
      "alternatives": [
        {
          "transcript": "cat",
          "confidence": 0.9999999
        }
      ]
    }
  ]
}

我为上述请求的 data/body 部分成功生成了多行...

要求：

for i in 1 2 3
do
echo "{\"config\": {\"languageCode\": \"pt-BR\", \"audioChannelCount\": 2},\"audio\":{\"uri\": \"gs://PROJECTID/$i.flac\"}}"
done

回复：

{"config": {"languageCode": "pt-BR", "audioChannelCount": 2},"audio":{"uri": "gs://PROJECTID/1.flac"}}
{"config": {"languageCode": "pt-BR", "audioChannelCount": 2},"audio":{"uri": "gs://PROJECTID/2.flac"}}
{"config": {"languageCode": "pt-BR", "audioChannelCount": 2},"audio":{"uri": "gs://PROJECTID/3.flac"}}

我如何组合这两个脚本，以便 curl API 对三个文件中的每一个执行一次，并得到如下响应：

{
      "results": [
        {
          "alternatives": [
            {
              "transcript": "cat",
              "confidence": 0.9999999
            }
          ]
        }
      ]
    }
{
      "results": [
        {
          "alternatives": [
            {
              "transcript": "dog",
              "confidence": 0.9999999
            }
          ]
        }
      ]
    }
{
      "results": [
        {
          "alternatives": [
            {
              "transcript": "horse",
              "confidence": 0.9999999
            }
          ]
        }
      ]
    }

Answer 1

你的代码几乎是正确的。

for i in 1 2 3
do
    curl -s -H "Content-Type: application/json" \
         -H "Authorization: Bearer ACCESSTOKEN" \
         -d '{"config": {"languageCode": "pt-BR", "audioChannelCount": 2}
             ,"audio":{"uri": "gs://PROJECTID/'$i'.flac"}}' \
          https://speech.googleapis.com/v1/speech:recognize
 done

我把URL放在最后，因为通常选项在参数之前

-d 的值由 3 个部分 ['...'] [$i] ['...'] 链接在一起组成。这允许扩展 [$i]
