优化这段代码@PostMapping("/login") @ResponseBody @PassToken public Object login(String username,String password) throws IOException { String url="http://42.177.95.222:9202/platform/yugang/task/getToken"; HttpClient client = HttpClients.createDefault(); //默认post请求 HttpPost post = new HttpPost(url); //拼接多参数 JSONObject json = new JSONObject(); json.put("username", "渔业协会"); json.put("password", "Yuye!@#qwe"); post.addHeader("Content-type", "application/json; charset=utf-8"); post.setHeader("Accept", "application/json"); post.setEntity(new StringEntity(json.toString(), Charset.forName("utf-8"))); HttpResponse httpResponse = client.execute(post); HttpEntity entity = httpResponse.getEntity(); String s = EntityUtils.toString(entity); JSONObject jo = JSONObject.parseObject(s); String token = jo.getJSONObject("data").getString("token"); System.out.println("dsadasdasdsadasd"+token); return verify(token); } public Object verify(String token) throws IOException { String url="http://42.177.95.222:9202/platform/yugang/task/verify"; HttpClient client = HttpClients.createDefault(); //默认post请求 HttpPost post = new HttpPost(url); //拼接多参数 JSONObject json = new JSONObject(); json.put("token",token); post.addHeader("Content-type", "application/json; charset=utf-8"); post.setHeader("Accept", "application/json"); post.setEntity(new StringEntity(json.toString(), Charset.forName("utf-8"))); HttpResponse httpResponse = client.execute(post); HttpEntity entity = httpResponse.getEntity(); String s = EntityUtils.toString(entity); JSONObject jo = JSONObject.parseObject(s); return jo; }

这段代码的优化点有以下几个：

1. 将重复的代码抽取成公共方法，避免代码冗余。
2. 使用连接池管理 HttpClient 的连接，提高连接的复用率和性能。
3. 使用 try-with-resources 语句关闭 HttpClient 和 HttpEntity 对象，避免资源泄漏。

下面是代码优化后的示例：

private static final String BASE_URL = "http://42.177.95.222:9202/platform/yugang/task";

private CloseableHttpClient httpClient = HttpClientBuilder.create()
        .setMaxConnTotal(200)
        .setMaxConnPerRoute(100)
        .build();

@PostMapping("/login")
@ResponseBody
@PassToken
public Object login(String username, String password) throws IOException {
    String token = getToken();
    System.out.println("dsadasdasdsadasd" + token);
    return verify(token);
}

private String getToken() throws IOException {
    String url = BASE_URL + "/getToken";
    HttpPost post = new HttpPost(url);
    post.addHeader("Content-type", "application/json; charset=utf-8");
    post.setHeader("Accept", "application/json");
    JSONObject json = new JSONObject();
    json.put("username", "渔业协会");
    json.put("password", "Yuye!@#qwe");
    post.setEntity(new StringEntity(json.toString(), Charset.forName("utf-8")));

    try (CloseableHttpResponse response = httpClient.execute(post)) {
        HttpEntity entity = response.getEntity();
        if (entity != null) {
            String s = EntityUtils.toString(entity);
            JSONObject jo = JSONObject.parseObject(s);
            return jo.getJSONObject("data").getString("token");
        }
        return null;
    }
}

private JSONObject verify(String token) throws IOException {
    String url = BASE_URL + "/verify";
    HttpPost post = new HttpPost(url);
    post.addHeader("Content-type", "application/json; charset=utf-8");
    post.setHeader("Accept", "application/json");
    JSONObject json = new JSONObject();
    json.put("token", token);
    post.setEntity(new StringEntity(json.toString(), Charset.forName("utf-8")));

    try (CloseableHttpResponse response = httpClient.execute(post)) {
        HttpEntity entity = response.getEntity();
        if (entity != null) {
            String s = EntityUtils.toString(entity);
            return JSONObject.parseObject(s);
        }
        return null;
    }
}

在优化后的代码中，我们将 HttpClient 对象的创建和关闭都放在了方法外部，使用连接池管理 HttpClient 的连接，提高连接的复用率和性能。同时，我们也将 getToken 和 verify 方法抽取出来，避免了代码冗余。最后，我们使用了 try-with-resources 语句来关闭 HttpClient 和 HttpEntity 对象，避免了资源泄漏。
