在Apache HttpClient库中,如果你想转发原始请求(比如POST、PUT等),你可以使用`HttpAsyncClient`配合`HttpRequestExecutor`来实现。以下是一个简单的步骤:
1. **创建HttpClient实例**:
```java
CloseableHttpResponse response = null;
try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
// ...
}
```
2. **创建请求**:
```java
HttpPost request = new HttpPost("http://target.com");
request.setHeader("Content-Type", "application/json"); // 如果有特定内容类型
```
3. **设置转发目标**:
```java
HttpHost targetHost = new HttpHost("forwarded.com", 80, "http");
request.setURI(new URI(targetHost.toURI().getSchemeSpecificPart()));
```
4. **创建请求执行者并执行请求**:
```java
BasicExecutionAwareRequestExecutor executor = new BasicExecutionAwareRequestExecutor(httpClient);
Future<CloseableHttpResponse> future = executor.execute(request);
// 等待响应完成
response = future.get();
```
5. **处理转发后的响应**:
```java
HttpEntity entity = response.getEntity();
String responseBody = EntityUtils.toString(entity, StandardCharsets.UTF_8); // 解析响应内容
```
注意:这只是一个基本示例,实际应用中可能需要处理异常、连接管理、线程池等问题。
