Speech recognition google语音识别ajax调用中的400错误请求错误 google语音识别ajax调用中的400错误请求错误

我收到响应消息，因为收到了无效的JSON负载。未知名称“配置[编码]”：无法绑定查询参数。在请求消息中找不到字段“config[encoding]”。接收到无效的JSON负载。未知名称“config[languageCode]”：无法绑定查询参数。在请求消息中找不到字段“config[languageCode]”。接收到无效的JSON负载。未知名称“音频[内容]”：无法绑定查询参数。在请求消息中找不到字段“音频[内容]”。接收到无效的JSON负载。未知名称“config[sampleRateHertz]”：无法绑定查询参数。在请求消息中找不到字段“config[sampleRateHertz]”。

但是相同的JSON负载和带有令牌密钥的URL在postman中运行良好

 var jsonObjects ={  "audio": {
                                "content": mainStringBuf
                                   },
                          "config": {
                                "encoding":"FLAC",
                                "sampleRateHertz":16000,
                                "languageCode":"en-US"
                               }
                        };

    $(document).ready(function(){
        $('#speechID').click(function(){
       jQuery.ajax({
                  url: "https://speech.googleapis.com/v1/speech:recognize?key=myKey" ,
                  type: "POST",
                  data: jsonObjects,
                  dataType: "json",
                  beforeSend: function(x) {
                    if (x && x.overrideMimeType) {
                      x.overrideMimeType("Content-Type:application/json");  
                      alert("beforeSend");
                    }
                  },
                  success: function(result) {
                    alert("result");
                  },
                  error: function(error){
                      alert("error");
                  }
        });
    });
                });

使用acount（）中的Google Cloud API密钥，尝试下面的代码，替换脚本中的API密钥：

$( document ).ready(function() {

    // The settings for the Ajax Request
    var settings = {
        "async": true,
        "crossDomain": true,
        "url": "https://speech.googleapis.com/v1/speech:recognize",
        "method": "POST",
        "headers": {
            "x-goog-api-key": "**your-api-key**",
            "content-type": "application/json",
            "cache-control": "no-cache",
        },
        "processData": false,
        "data": "{'audio':{'content':'"+mainStringBuf+"'},'config': {'encoding':'FLAC','sampleRateHertz':'16000','languageCode':'en-US'}}"
    }

    // The Ajax Request, on success play the speech
    $.ajax(settings).done(function (response) {
      console.log(response);
    });

});
