Google 云文字转语音 returns "INVALID_ARGUMENT"

Question

我正在尝试 Google Cloud 使用 REST 的文本转语音。使用 Google's API explorer.

时效果很好

但是当我尝试进行 post 调用时，returns 出现以下错误（我使用的 API 键没有任何限制）：

{
  "error": {
    "code": 400,
    "message": "Invalid JSON payload received. Unknown name \"{\r\n \"audioConfig\": {\r\n  \"audioEncoding\": \"MP3\"\r\n },\r\n \"input\": {\r\n  \"text\": \"This is a text to speak\"\r\n },\r\n \"voice\": {\r\n  \"languageCode\": \"en-US\",\r\n  \"name\": \"en-US-Standard-B\"\r\n }\r\n}\": Cannot bind query parameter. Field '{\r\n \"audioConfig\": {\r\n  \"audioEncoding\": \"MP3\"\r\n },\r\n \"input\": {\r\n  \"text\": \"This is a text to speak\"\r\n },\r\n \"voice\": {\r\n  \"languageCode\": \"en-US\",\r\n  \"name\": \"en-US-Standard-B\"\r\n }\r\n}' could not be found in request message.",
    "status": "INVALID_ARGUMENT",
    "details": [
      {
        "@type": "type.googleapis.com/google.rpc.BadRequest",
        "fieldViolations": [
          {
            "description": "Invalid JSON payload received. Unknown name \"{\r\n \"audioConfig\": {\r\n  \"audioEncoding\": \"MP3\"\r\n },\r\n \"input\": {\r\n  \"text\": \"This is a text to speak\"\r\n },\r\n \"voice\": {\r\n  \"languageCode\": \"en-US\",\r\n  \"name\": \"en-US-Standard-B\"\r\n }\r\n}\": Cannot bind query parameter. Field '{\r\n \"audioConfig\": {\r\n  \"audioEncoding\": \"MP3\"\r\n },\r\n \"input\": {\r\n  \"text\": \"This is a text to speak\"\r\n },\r\n \"voice\": {\r\n  \"languageCode\": \"en-US\",\r\n  \"name\": \"en-US-Standard-B\"\r\n }\r\n}' could not be found in request message."
          }
        ]
      }
    ]
  }
}

请求正文：

{
 "audioConfig": {
  "audioEncoding": "MP3"
 },
 "input": {
  "text": "This is a text to speak"
 },
 "voice": {
  "languageCode": "en-US",
  "name": "en-US-Standard-B"
 }
}

基于此Text-to-Speech Quickstart

我成功完成了以下 POST 请求：

curl -X POST \
  -H "Content-Type: application/json; charset=utf-8" \
  --data "{
    'input':{
      'text':'This is a text to speak'
    },
    'voice':{
      'languageCode':'en-US',
      'name':'en-US-Standard-B'
    },
    'audioConfig':{
      'audioEncoding':'MP3'
    }
  }" "https://texttospeech.googleapis.com/v1/text:synthesize?key=MY_KEY" > synthesize-text.txt

希望对您有所帮助。
