我正在尝试使用Go 1.11中亚马逊的新流式转录API.目前亚马逊只提供Java SDK,所以我尝试的是低级方式.

唯一相关的文档是在这里,但它没有显示端点.我在Java示例中找到了它https://transcribestreaming.<region>.amazonaws.com并且我正在尝试爱尔兰地区,即https://transcribestreaming.eu-west-1.amazonaws.com.这是我打开HTTP/2双向流的代码:

import (
    "crypto/tls"
    "github.com/aws/aws-sdk-go-v2/aws"
    "github.com/aws/aws-sdk-go-v2/aws/external"
    "github.com/aws/aws-sdk-go-v2/aws/signer/v4"
    "golang.org/x/net/http2"
    "io"
    "io/ioutil"
    "log"
    "net/http"
    "os"
    "time"
)

const (
    HeaderKeyLanguageCode   = "x-amzn-transcribe-language-code"  // en-US
    HeaderKeyMediaEncoding  = "x-amzn-transcribe-media-encoding" // pcm only
    HeaderKeySampleRate     = "x-amzn-transcribe-sample-rate"    // 8000, 16000 ... 48000
    HeaderKeySessionId      = "x-amzn-transcribe-session-id"     // For retrying a session. Pattern: [a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}
    HeaderKeyVocabularyName = "x-amzn-transcribe-vocabulary-name"
    HeaderKeyRequestId = "x-amzn-request-id"
)

...

region := "eu-west-1"

cfg, err := external.LoadDefaultAWSConfig(aws.Config{
    Region: region,
})
if err != nil { …
