这里写目录标题
- 1 远程获取cookie
- 2 远程调用其他项目（传参，携带cookie）
1 远程获取cookie
参数 url 是远程项目的地址。map集合是参数
代码语言：javascript复制 /**
* @Description: 登录成功获取cookie
*/
public static Map<String, Object> postForForm(String url, Map<String, String> parms) {
HttpPost httpPost = new HttpPost(url);
ArrayList<BasicNameValuePair> list = new ArrayList<>();
parms.forEach((key, value) -> list.add(new BasicNameValuePair(key, value)));
CloseableHttpClient httpClient = HttpClients.createDefault();
try {
if (Objects.nonNull(parms) && parms.size() >0) {
httpPost.setEntity(new UrlEncodedFormEntity(list, "UTF-8"));
}
httpPost.setHeader("Content-type", "application/x-www-form-urlencoded");
InputStream content = httpPost.getEntity().getContent();
InputStreamReader inputStreamReader = new InputStreamReader(content, "UTF-8");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String readLine = bufferedReader.readLine();
String s = URLDecoder.decode(readLine, "UTF-8");
HttpResponse response = httpClient.execute(httpPost);
HttpEntity entity = response.getEntity();
Header[] allHeaders = response.getAllHeaders();
// 遍历以获取名为"Set-Cookie"的响应头，并赋值给变量cookie
String cookie = "";
for (Header header : allHeaders) {
if ("Set-Cookie".contentEquals(header.getName())) {
cookie = header.getValue();
}
}
// System.out.println(cookie);
String result= EntityUtils.toString(entity, "UTF-8");
Map<String, Object> stringObjectHashMap = new HashMap<>();
stringObjectHashMap.put("cookie",cookie);
stringObjectHashMap.put("result",result);
return stringObjectHashMap;
}catch (IOException e) {
e.printStackTrace();
}finally {
if (Objects.nonNull(httpClient)){
try {
httpClient.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return null;
}controller层
代码语言：javascript复制 public void getXxlJobToken( ) {
Map<String, String> sendMsg = new HashMap<String, String>();
sendMsg.put("userName", userName);
sendMsg.put("password", password);
sendMsg.put("ifRemember", ifRemember);
Map<String, Object> stringObjectMap = HttpSSLUtil.postForForm(webLoginUrl, sendMsg);
Cookieinfo = (String) stringObjectMap.get("cookie");
// System.out.println(Cookieinfo);
}远程地址 接收参数代码
代码语言：javascript复制 @RequestMapping(value="login", method=RequestMethod.POST)
@ResponseBody
@PermissionLimit(limit=false)
public ReturnT<String> loginDo(HttpServletRequest request, HttpServletResponse response, String userName, String password, String ifRemember){
boolean ifRem = (ifRemember!=null && ifRemember.trim().length()>0 && "on".equals(ifRemember))?true:false;
return loginService.login(request, response, userName, password, ifRem);
}2 远程调用其他项目（传参，携带cookie）
工具类方法
代码语言：javascript复制 /**
* @Description: 携带cookie进行调用
*/
public static String postForFormCookie(String url111, String parms,String cookies) {
OutputStreamWriter out = null ;
BufferedReader in = null;
StringBuilder result = new StringBuilder();
// String url111 = "http://192.168.1.5:8080/xxl-job-admin/jobinfo/updatedemo";
try {
URL realUrl = new URL(url111);
// 打开和URL之间的连接
HttpURLConnection conn = (HttpURLConnection)realUrl.openConnection();
//设置通用的请求头属性
// conn.setRequestMethod("POST");
conn.setRequestProperty("Cookie", cookies);
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("Content-type", "application/x-www-form-urlencoded");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
// 发送POST请求必须设置如下两行 否则会抛异常（java.net.ProtocolException: cannot write to a URLConnection if doOutput=false - call setDoOutput(true)）
conn.setDoOutput(true);
conn.setDoInput(true);
//获取URLConnection对象对应的输出流并开始发送参数
out = new OutputStreamWriter(conn.getOutputStream(), "UTF-8");
//添加参数
// DataOutputStream output = null;
// output = new DataOutputStream(conn.getOutputStream());
out.write(parms);
// output.writeBytes(xxlJobInfo1.toString());
out.flush();
in = new BufferedReader(new InputStreamReader(conn.getInputStream(),"UTF-8"));
String line;
while ((line = in.readLine()) != null) {
result.append(line);
}
return result.toString();
} catch (Exception e) {
e.printStackTrace();
}finally {// 使用finally块来关闭输出流、输入流
try {
if (out != null) {
out.close();
}
if (in != null) {
in.close();
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
return null;
// System.out.println(result.toString());
}使用
代码语言：javascript复制 String updatepath= addressInfo "/jobinfo/update";
// System.out.println(updatepath);
String param = "&id=" id "&jobGroup=";
String s = HttpSSLUtil.postForFormCookie(updatepath,param, XxlJobController.Cookieinfo);远程项目可以使用实体类进行接收
代码语言：javascript复制 /**
* 更新任务
*/
@RequestMapping("/update")
@ResponseBody
public ReturnT<String> update(XxlJobInfo jobInfo) {
return xxlJobService.update(jobInfo);
}
