需要有关使用com.google.api.client.http.HttpRequest的POST请求的帮助

<dependency>
    <groupId>com.google.http-client</groupId>
    <artifactId>google-http-client</artifactId>
    <version>1.41.0</version>
</dependency>

HttpTransport httpTransport = new NetHttpTransport();
HttpRequestFactory requestFactory = httpTransport.createRequestFactory();

GenericUrl url = new GenericUrl("http://example.com/api/endpoint");
HttpRequest request = requestFactory.buildPostRequest(url, new ByteArrayContent("application/json", requestBody.getBytes()));

HttpResponse response = request.execute();
String responseBody = response.parseAsString();
