In order to consider the secondary development in the future, and the increase of the code in the future. Call the interface of the workflow, and write a lot of code in your own new project.
Workflow interface:
public boolean sendMail(Map lhm){
//Set the URL address of the HTTP connection, which is the URL of the second application. If on the same computer you can change 192.168.1.134 to 127.0.0.1 or localhost
try {
String http="http://localhost:8080/SDKFlow/email.action";
URL url=new URL(http);
// Generate HttpURLConnection connection
HttpURLConnection httpurlconnection=(HttpURLConnection) url.openConnection();
//The output stream is set, the default is false, that is, parameters cannot be passed.
httpurlconnection.setDoOutput(true);
//Set the way to send the request. Note: Be sure to capitalize
httpurlconnection.setRequestMethod("POST");
//Set the connection timeout time. However, if it is not set, in the case of abnormal network, it may cause the program to freeze and cannot continue to execute downward, so generally set a timeout time. in milliseconds
httpurlconnection.setConnectTimeout(30000);
//Set the output stream.
OutputStreamWriter writer=new OutputStreamWriter(httpurlconnection.getOutputStream(), "utf-8");
//The passed parameters are separated by & symbol.
writer.write("authid="+lhm.get("authid")+"&title="+lhm.get("title"));
//Used to flush the buffer stream. Because by default, she will write to the buffer stream of the memory, and will only write when a certain amount of data is reached. Using this command allows him to write immediately, otherwise the stream will be closed
next writer.flush();
// It is used to close the output stream. After it is closed, data cannot be output, so use flush to flush the buffer stream
writer.close();
//Get the returned request.
int responseCode=httpurlconnection.getResponseCode();
System.out.println("OK"+responseCode);
//Get the output stream of the server. Get the returned data
InputStream urlstream=httpurlconnection.getInputStream();
BufferedReader reader=new BufferedReader(new InputStreamReader(urlstream));
String line;
String tline="";
while((line=reader.readLine())!=null) {
tline+=line;
}
//Output all data
System.out.println(tline);
return true;
}else{
System.out.println("ERR"+responseCode);
}
} catch (Exception e) {
