Springboot 实现curl调用

要在Spring Boot中实现Curl调用，您可以使用Java的HttpURLConnection或Apache HttpClient库。下面是使用Apache HttpClient库的示例代码：

首先，确保在您的项目中包含以下Maven依赖项：

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.13</version>
</dependency>

然后，您可以创建一个CurlUtil类来执行Curl调用：

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.IOException;

public class CurlUtil {
    public static String sendGetRequest(String url) throws IOException {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        HttpGet httpGet = new HttpGet(url);

        HttpResponse response = httpClient.execute(httpGet);
        HttpEntity entity = response.getEntity();
        
        String responseString = EntityUtils.toString(entity);

        httpClient.close();

        return responseString;
    }
}

现在，您可以在您的Spring Boot应用程序中使用CurlUtil类来进行Curl调用。例如，您可以在控制器中使用以下代码：

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/api")
public class MyController {
    @GetMapping("/curl")
    public String performCurlCall() {
        try {
            String response = CurlUtil.sendGetRequest("YOUR_CURL_URL");
            return response;
        } catch (IOException e) {
            e.printStackTrace();
            return "Error occurred while performing Curl call.";
        }
    }
}

请将 "YOUR_CURL_URL" 替换为实际的Curl URL。现在，当您访问`http://localhost:8080/api/curl`时，将执行Curl调用并返回响应结果。

这是使用Spring Boot实现Curl调用的基本示例。根据您的需求，您可以扩展此示例以满足更复杂的需求。
