接口返回html頁面展現在瀏覽器

近期作接口對接時，對方直接返回整個html頁面，把我整懵了，特此記錄下。

網上有不少人提出採用 中轉頁面 的方式，本文另闢蹊徑，採起後端方式解決。

1. 導包

<dependency>
    <groupId>org.jsoup</groupId>
    <artifactId>jsoup</artifactId>
    <version>1.12.1</version>
</dependency>

 

2. 上代碼

package cn.sd.service.impl;

import cn.sd.service.SpeedServiceI;
import cn.sd.utils.OutKey;
import cn.sd.utils.WxApi;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

/**

 * @description

@Service
public class SpeedServiceImpl implements SpeedServiceI {
    private static final Logger logger = LoggerFactory.getLogger(SpeedServiceImpl.class);
    /**
     * 某公衆號的appid
     */
    private String appId = "***********";
    /**
     * 約定的密鑰
     */
    private String clearly = "###########";

    @Override
    public void showHtmlPage(String openId, String phone, String card, HttpServletResponse response) {
        response.setContentType("text/html;charset=utf-8");
        PrintWriter writer;
        try {
            writer = response.getWriter();
        } catch (IOException e) {
            writer = new PrintWriter(System.out);
            logger.error("IO異常:", e);
        }

        Map userInfo = WxApi.getUserInfo(appId, openId);
        logger.info("關注用戶信息：" + userInfo);

        Map bindUserInfo = WxApi.getBindingMobileEntity(appId, openId);
        logger.info("綁定用戶信息：" + bindUserInfo);

        if (userInfo == null || bindUserInfo == null || userInfo.isEmpty() || bindUserInfo.isEmpty()) {
            logger.info("請關注【某公衆號】並綁定手機號後訪問");
            writer.println("請關注【某公衆號】並綁定手機號後訪問");
        } else {
            //1 關注
            String subscribe = String.valueOf(userInfo.get("subscribe"));
            //Y 綁定
            String bindStatus = (String) bindUserInfo.get("bindingStatus");
            logger.info("bindStatus:" + bindStatus + " && subscribe:" + subscribe);

            if ("Y".equals(bindStatus) && "1".equals(subscribe)) {
                //手機號碼加密
                String nbr = OutKey.encrypt(phone, clearly);
                //中文加密
                String area = OutKey.encrypt(card, clearly);
                String speedUrl = "http://***.**.***.**:****/***?nbr={nbr}&area={area}&clearly={clearly}";
                Map<String, String> map = new HashMap<>(4);
                map.put("nbr", nbr);
                map.put("area", area);
                map.put("clearly", clearly);
                logger.info("map:{}", map);
                RestTemplate restTemplate = new RestTemplate();
                String html = restTemplate.getForObject(speedUrl, String.class, map);
                Document document = Jsoup.parse(html);
                logger.info("document:{}", document);
                writer.println(document.outerHtml());
            } else {
                logger.info("請綁定手機號後訪問");
                writer.println("請綁定手機號後訪問");
            }
        }
        writer.close();
    }
}

不加 response.setContentType("text/html;charset=utf-8"); 的話，中文會變成???

 

3. 配置文件

application.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--  加載靜態資源  -->
    <mvc:annotation-driven />
    <mvc:resources mapping="/css/**" location="/css/" />
    <mvc:resources mapping="/images/**" location="/images/" />
    <mvc:resources mapping="/js/**" location="/js/" />

    <!-- 包掃描 -->
    <context:component-scan base-package="cn.sd.controller, cn.sd.service"/>

</beans>

這裏沒打算說的，但當時本身忘記加靜態資源配置了，致使樣式未顯示出來。(樣式、圖片等靜態資源找對方要)

 

至此，完成。
