java怎么调用http接口并传入waz音频文件做为参数

要调用HTTP接口并传入WAV音频文件作为参数，可以使用Java的HTTP客户端库，如Apache HttpClient或OkHttp。

以下是使用Apache HttpClient发送HTTP POST请求并传输WAV音频文件的示例代码：

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.File;
import java.io.IOException;

public class HttpPostExample {

    public static void main(String[] args) throws IOException {

        // 创建HTTP客户端
        CloseableHttpClient httpClient = HttpClients.createDefault();

        // 创建HTTP POST请求
        HttpPost httpPost = new HttpPost("http://example.com/api");

        // 创建HTTP multipart请求体
        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.addBinaryBody("audio_file", new File("/path/to/audio.wav"), ContentType.APPLICATION_OCTET_STREAM, "audio.wav");

        // 设置HTTP请求体
        httpPost.setEntity(builder.build());

        // 执行HTTP POST请求
        CloseableHttpResponse response = httpClient.execute(httpPost);

        try {
            // 处理HTTP响应
            HttpEntity entity = response.getEntity();
            String responseString = EntityUtils.toString(entity, "UTF-8");
            System.out.println(responseString);
        } finally {
            response.close();
        }
    }
}

在上述代码中，我们创建了一个HTTP POST请求并设置了请求体为一个multipart请求体，其中包含一个名为“audio_file”的文件参数，文件的内容来自于本地路径为“/path/to/audio.wav”的WAV音频文件。我们使用Apache HttpClient执行HTTP请求并处理HTTP响应。
