我想使用類的CGI腳本輸出Java到HTML。爲什麼我的CGI Java to HTML輸出在最後被切斷？
我想知道爲什麼我似乎無法正確比較我檢查的變量的值。該代碼有效，但無法設法比較這些變量，並且不能正確結束HTML代碼。由於某種原因，它從未達到代碼的末尾。 （從來沒有寫出結束的身體和HTML標記）
post.java
import java.io.*;
public class post {
public static void main(String [] args) {
System.out.println("Content-Type: text/html\n\n");
System.out.println("<HTML><BODY>");
System.out.println("<h1>Here is your stupid user report:</h1>");
String fullname = "";
String address = "";
String city = "";
String state = "";
String washhands = "";
String takeshower = "";
boolean stupidity = false;
String comments = "";
String data = "";
try {
BufferedReader br =
new BufferedReader(new InputStreamReader(System.in));
data = br.readLine();
} catch(IOException ioe) {
System.out.println ("IOException reading POST data: " + ioe);
}
if (data.length() > 0) {
String[] paramArray = data.split("&");
for(String param : paramArray){
String[] paramVals = param.split("=");
String paramName = paramVals[0];
System.out.println(paramName + "<br/>");
String paramVal = paramVals[1];
System.out.println(paramVal + "<br/>");
if (paramName == "fullname") fullname = paramVal;
if (paramName == "address") address = paramVal;
if (paramName == "city") city = paramVal;
if (paramName == "state") state = paramVal;
if (paramName == "washhands") washhands = paramVal;
if (paramName == "takeshower") takeshower = paramVal;
if (paramName == "stupidity") stupidity = true;
if (paramName == "comments") comments = paramVal;
}
System.out.println("HELLOOOOO");
if (fullname != ""){
System.out.println("Here we have <font color=blue>" + fullname + "</font> ");
}
if (fullname == ""){
System.out.println("Here's a <i>nobody</i> ");
}
if (address != ""){
System.out.print("who lives on <font size=20>" + address + "</font> ");
}
if (city != ""){
System.out.print("from the city of <u>" + city + "</u> ");
}
if (state != ""){
System.out.print("in the state of <b><u>" + state + "</u></b> ");
}
if (washhands != ""){
if (washhands == "no") System.out.print("who <b>doesn't</b> wash his/her hands after using the bathroom...");
if (washhands == "yes") System.out.print("who washes his/her hands after using the bathroom...");
}
if (takeshower != ""){
if (takeshower == "everyday") System.out.println("<center>He/she takes a shower everyday.</center>");
if (takeshower == "never") System.out.println("<center>He/she never takes a shower.</center>");
}
if (stupidity == true){
System.out.println("<tt>He/she is stupid.</tt>");
}
if (comments != ""){
System.out.println("<h3>Here are what he thinks about this assignment:" + comments + "</h3>");
}
}
System.out.println("</BODY></HTML>");
}
}
，我使用的CGI文件 - post.cgi（位於/cgi-bin/post.cgi）
#!/bin/sh
java post
，我使用允許輸入HTML文件： post.html
<html>
<head>

如果你能認罪e指出任何可能出現問題的東西......調試輸出的工作原理，因爲它會管理輸出變量值，但由於某種原因完全忽略了if語句。
Stackoverflow不會讀通過所有。請嘗試將其縮小到更具體的問題。換句話說：調試。 – OmniOwl
問題是爲什麼它忽略了if語句... –
然後你應該把它縮減到這個範圍，在你展示你調試它之後。 – OmniOwl
