Java使用CloseableHttpClient调用第三方接口

1. 依赖

        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.2</version>
        </dependency>

2. 接口

@PostMapping("/webGlLogin")
@ApiOperation(value = "登录")
public ResponseVo webGlLogin(@RequestBody WebGlModel webGlModel) {
    return indexService.webGlLogin(webGlModel);
}

3. 逻辑

public ResponseVo webGlLogin(WebGlModel webGlModel) {
    CloseableHttpClient httpClient = HttpClientBuilder.create().build();

    // post请求
    HttpPost httpPost = new HttpPost("https://www.ilab-x.com/open/api/v2/user/validate?username=" + webGlModel.getUsername()
            + "&password=" + webGlModel.getPassword()
            + "&nonce=" + webGlModel.getNonce()
            + "&cnonce=" + webGlModel.getCnonce()
            + "&appid=" + webGlModel.getAppid()
            + "&signature=" + webGlModel.getSignature());
    httpPost.setHeader("Content-Type", "application/json;charset=utf8");

    // 响应模型
    CloseableHttpResponse response = null;
    try {
        response = httpClient.execute(httpPost);
        HttpEntity responseEntity = response.getEntity();
        if (responseEntity != null) {
            return ResponseVo.success(HttpStatus.SUCCESS, "操作成功", EntityUtils.toString(responseEntity));
        }
    } catch (Exception e) {
        return ResponseVo.error(HttpStatus.ERROR, "请求调用失败", e.getMessage());
    } finally {
        try {
            // 释放资源
            if (httpClient != null) {
                httpClient.close();
            }
            if (response != null) {
                response.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    return ResponseVo.error(HttpStatus.ERROR, "服务器异常，请联系管理员", null);
}
