VPC访问

本文介绍用户如何在自己的VPC内访问TPP服务。TPP会自动为您的VPC建立私网连接Privatelink，让您可以在自己的VPC内访问TPP服务。注意：VPC内访问TPP服务是非常安全的，它隔离了公网、其它专有网络，如果您想在公网访问请参考文档公网调试。

网络结构

TPP会自动为您的VPC建立私网连接Privatelink，让您可以在自己的VPC内访问TPP云服务。

您会使用到【VPC访问域名】（即Privatelink连接提供的终端节点域名），来访问TPP云服务。

前置条件

详情请参考使用流程

1. 您已经成功购买了TPP实例

2. 并将方案代码发布到正式环境

3. 创建并发布好场景实验

协议

协议	方法	demo
HTTP	GET	http://${domain}/recommend?_input_charset=UTF-8&_output_charset=UTF-8&_instance_cluster=${instanceId}&appid=${sceneId}&yourRequestParam=
HTTP	POST （推荐）	url http://${domain}/recommend? header "Content-Type:application/x-www-form-urlencoded" body _instance_cluster=${instanceId}&appid=${sceneId}&yourRequestParam=

各语言示例

• GET

curl -i "http://${domain}/recommend?_input_charset=UTF-8&_output_charset=UTF-8&_instance_cluster=${instanceId}&appid=${sceneId}&yourRequestParam="

• POST

curl --location --request POST 'http://${domain}/recommend' \

--data-urlencode '_output_charset=UTF-8' \
--data-urlencode '_instance_cluster=${instanceId}' \
--data-urlencode 'appid=${sceneId}' \
--data-urlencode 'yourRequestParam=${yourRequestParam}'

• GET

  .method("GET",null)
  .addHeader("Content-Type", "application/x-www-form-urlencoded")
  .build();
Response response = client.newCall(request).execute();

• POST

OkHttpClient client = new OkHttpClient().newBuilder().build();
MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
RequestBody body = RequestBody.create(mediaType, "_input_charset=UTF-8&_output_charset=UTF-8&_instance_cluster=${instanceId}&appid=${sceneId}&yourRequestParam=${yourRequestParam}");
