当我尝试使用 Jsoup 在我的 class 中获取多个文档时，为什么会出现 handshake_failure 错误？
[英]Why do I get a handshake_failure error when I try to get more than 1 Document in my class using Jsoup?
问题描述
It seems as if I can only create one get request with Jsoup per class because, when I swap out CITYPARKSURL for CITYPARKSURL2 , the one that I put in getParkNames() compiles and the other gives the error.
似乎我只能为每个 class 创建一个使用 Jsoup 的 get 请求，因为当我将CITYPARKSURL CITYPARKSURL2时，我放入getParkNames()的那个会编译，而另一个会给出错误。
I had this code running in IntelliJ but, when I moved it into Eclipse, it started giving me these handshake errors.我在 IntelliJ 中运行了这段代码，但是当我将它移到 Eclipse 中时，它开始给我这些握手错误。 Does anyone know why this is?有人知道为什么吗？ (I have to do my project in Eclipse unfortunately.) （不幸的是，我必须在 Eclipse 中完成我的项目。）
Here is my code and the error:这是我的代码和错误：
public class DublinCityParksParse{
private final String CITYPARKSURL = "https://www.dublincity.ie/residential/parks/dublin-city-parks/visit-park";
private final String CITYPARKSURL1 = "https://www.dublincity.ie/residential/parks/dublin-city-parks/visit-park?page=1";
private final String CITYPARKSURL2 = "https://www.dublincity.ie/residential/parks/dublin-city-parks/visit-park?page=2";
private final String CITYPARKSURL3 = "https://www.dublincity.ie/residential/parks/dublin-city-parks/visit-park?page=3";
private String[] parkNamesHyphs = {"/eamonn-ceannt-park", "/balcurris"};
private List<String> parkNames = new ArrayList<String>();
private ArrayList<String> parkNamesHyphen = new ArrayList<String>();
private List<Park> parks = new ArrayList<Park>();
public DublinCityParksParse() {
getParkNames();
getParkNames1();
}
public void getParkNames() {
try {
Document docGetDetails = Jsoup.connect(CITYPARKSURL).get();
Elements elsClass = docGetDetails.getElementsByClass("search-result__title");
for(Element els : elsClass) {
parkNames.add(els.text());
}
// System.out.println(docGetDetails.toString());
System.out.println(parkNames.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void getParkNames1() {
try {
Document docGetDetails1 = Jsoup.connect(CITYPARKSURL1).get();
Elements elsClass1 = docGetDetails1.getElementsByClass("search-result__title");
for(Element els : elsClass1) {
parkNames.add(els.text());
}
System.out.println(docGetDetails1.toString());
System.out.println(parkNames.toString());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[]args) {
new DublinCityParksParse();
}}

My bet is that you are running different Java versions between IntelliJ and Eclipse, and the Eclipse version is old (like 1.7 or an old 1.8).我敢打赌，您在 IntelliJ 和 Eclipse 之间运行不同的 Java 版本，并且 Eclipse 版本是旧的（如 1.7 或旧版本） And that's why it worked in the first IDE and not the second.这就是为什么它在第一个 IDE 而不是第二个中起作用的原因。
You should update your JDK to a currently supported version .您应该将 JDK 更新到当前支持的版本。 Those old versions of Java have troubles with current TLS / SSL websites.那些旧版本的 Java 在当前的 TLS / SSL 网站上存在问题。 They re missing many cipher suites, SNI support, TLS 1.3 support, etc. You can patch all that in for old versions, but I can't imagine that's something you want to do.他们缺少许多密码套件、SNI 支持、TLS 1.3 支持等。您可以为旧版本修补所有这些，但我无法想象这是您想要做的事情。
