1.3打开相关服务

使用Audio Editor Kit服务需要您在AppGallery Connect上打开Audio Editor Kit服务开关,具体操作步骤请参见打开服务开关。

2.歌声合成功能集成

2.1同步接口(流式)

2.1.1获取access_token鉴权信息

使用开发者联盟界面获得的客户端ID以及对应密钥,发送HTTPS POST请求,获取查询access_token。获取方式请参见客户端模式(Client Credentials)。

2.1.2调用同步接口(流式)

通过以上步骤获取的access_token信息,发送HTTPS POST调用同步接口(流式)。

示例代码(Java)如下所示:

其中requestUrl = "https://audioeditor-api-drcn.cloud.huawei.com/v1/audioeditor/gateway/ai/ttsing/sync"。

请点击下载MusicXML文件,并上传:

     /**
     * 调用同步接口(流式)
     * @throws Exception IO异常
     */
    private static void syncTask() throws Exception {
        // 设置请求header
        PostMethod postMethod = new PostMethod(requestUrl);
        // 设置文本类型(String),例:"application/json;charset=utf-8"
        postMethod.setRequestHeader("Content-Type", contentType);
        // 设置请求ID(String),例:"9af1aeda-531b-407a-80b4-65b40ef77bd6"
        postMethod.setRequestHeader("X-Request-ID", requestId);
        // 设置App包名(String),例:"com.huawei.demo"
        postMethod.setRequestHeader("X-Package-Name", pacageName);
        // 设置App所在国家(String),例:"cn"
        postMethod.setRequestHeader("X-Country-Code", countryCode);
        // 设置App标识(String),例:"9af1aeda-531b-407a-80b4-65b40ef77bd6"
        postMethod.setRequestHeader("HMS-APPLICATION-ID", applicationId);
        // 设置证书指纹(String),例:"xxxxxxxxxxxxxxx"
        postMethod.setRequestHeader("certFingerprint", certFingerprint);
        // 设置动态获取的AccessToken(String)
        postMethod.setRequestHeader("Authorization","Bearer " + accessToken);
        // 设置请求body
        Map<String, Object> bodyMap = new HashMap<>();
        Map<String, Object> dataMap = new HashMap<>();
        Map<String, Object> configMap = new HashMap<>();
        // filePath是MusicXML文件路径(含文件名、后缀)
        String lyricFilePath = "filePath";
        dataMap.put("lyric", FileUtils.readFileToString(new File(lyricFilePath), "UTF-8"));
        dataMap.put("language", "chinese");
        configMap.put("type", 1);
        configMap.put("outputEncoderFormat", 0);
        configMap.put("wordDurationForceAlign", "false");
        bodyMap.put("data", dataMap);
        bodyMap.put("config", configMap);
        RequestEntity requestEntity = new StringRequestEntity(JSONObject.toJSONString(bodyMap),"application/json" ,"UTF-8");
        postMethod.setRequestEntity(requestEntity);

        HttpClient httpClient = new HttpClient();
        int ret = httpClient.executeMethod(postMethod);
        if (ret == 200) {
            Header responseHeader = postMethod.getResponseHeader("content-type");
            if ("application/octet-stream".equals(responseHeader.getValue())) {
                InputStream rpsContent = postMethod.getResponseBodyAsStream();
                // filePath是要保存文件的路径(含文件名、PCM文件后缀)
                String filePath = "filePath";
                FileUtils.copyInputStreamToFile(rpsContent, new File(filePath));
            } else {
                String errorString = postMethod.getResponseBodyAsString();
                System.out.println(errorString);
            }
        } else {
            System.out.println("callApi failed: ret =" + ret + " rsp=" + postMethod.getResponseBodyAsString());
        }
    }
