java 调用HttpClient怎么也接收不到cookie的可能缘由

情况：使用HttpClient，发送POST请求A，想使用返回的cookie访问其他接口

结果：接口请求成功，返回200code码，结果访问其他接口时依旧需要登录

分析：访问A成功了，应该是cookie的问题，查看返回内容的cookie时，的确 也没有cookie，查看控制台报警告Invalid cookie header: “Set-Cookie: aid=1edc28ef-ff53-42b0-a94b-49b02f06994b; Path=/; Expires=Wed, 30 Sep 2020 09:36:43 GMT”. Invalid expires attribute: Wed, 30 Sep 2020 09:36:43 GMT

问题：cookie丢失了，跟后台警告有关，cookie解析格式的问题

解决方法：

RequestConfig defaultConfig = RequestConfig.custom().setCookieSpec(CookieSpecs.STANDARD).build();//这个是重点，修改cookie格式

HttpClientContext context = HttpClientContext.create();

Map paramMap =new HashMap<>();

paramMap.put(“t”,System.currentTimeMillis());

paramMap.put(“team_id”,”xxxx”);

paramMap.put(“name”,”xxx@yoyosys.com.cn”);

paramMap.put(“password”,”xxxx”);

paramMap.put(“locale”,”zh-cn”);

CloseableHttpClient httpClient = HttpClients.createDefault();

HttpPost httpPost =new HttpPost(“https://xxxx”);

httpPost.setConfig(defaultConfig);//这个是重点，将cookie配置方式放入请求中

httpPost.setHeader(“Content-Type”,”application/json;charset=UTF-8″);

httpPost.setHeader(“Connection”,”keep-alive”);

httpPost.setHeader(“Accept”,”application/json, text/plain, */*”);

httpPost.setHeader(“Accept-Encoding”,”gzip, deflate, br”);

httpPost.setHeader(“Sec-Fetch-Site”,”same-origin”);

httpPost.setHeader(“Sec-Fetch-Mode”,”cors”);

httpPost.setHeader(“Sec-Fetch-Dest”,”empty”);

httpPost.setHeader(“User-Agent”,”Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36″);

String param= JSONUtils.toJSONString(paramMap);

httpPost.setEntity(new StringEntity(param));

CloseableHttpResponse response = httpClient.execute(httpPost,context);
