具体步骤
首先,需要在公网创建应用然后查看服务接口认证信息APPID、APISecret、APIKey、URL。
https://console.xfyun.cn/services/bm3 点应用名称进去查看详情
然后点“文档”查看报文协议可以下载调用示例使用Java代码调用星火api
https://www.xfyun.cn/doc/spark/Web.html
下面仅仅是个示例具体代码要根据官网最新文档确定。注意domain在1.523版本分别传general,generalv2,generalv3传错了会报错10404。另外如果想同步返回结果需要自己使用CountDownLatch控制主线程等待一段时间 countDownLatch.await(30000, TimeUnit.MILLISECONDS); 这样会在指定的最大超时时间内等待。 import com.alibaba.fastjson.JSON;
