如何在 Java 中执行 HTTP Post 请求？

Question

我知道这个问题有几个答案，但似乎都不适用于我的情况。

我在 curl 中尝试做的操作是 curl -u 'user:pwd' https://localhost:8000/services/search/jobs --data search='search index=my_index'

例如，我可以在 python 中这样做：

import urllib
import httplib2
from xml.dom import minidom

baseurl = 'https://localhost:8000'
userName = 'user'
password = 'pwd'
searchQuery = 'index=my_index'
serverContent = httplib2.Http(disable_ssl_certificate_validation=True).request(baseurl + '/services/auth/login',
                                                                               'POST', headers={}, body=urllib.parse.urlencode({'username':userName, 'password':password}))[1]
sessionKey = minidom.parseString(serverContent).getElementsByTagName('sessionKey')[0].childNodes[0].nodeValue
searchQuery = searchQuery.strip()
if not (searchQuery.startswith('search') or searchQuery.startswith("|")):
    searchQuery = 'search ' + searchQuery
print (httplib2.Http(disable_ssl_certificate_validation=True).request(baseurl + '/services/search/jobs','POST',
                                                                   headers={'Authorization': 'Splunk %s' % sessionKey},body=urllib.parse.urlencode({'search': searchQuery}))[1])

但我为 java 研究的每个解决方案似乎都不适用于我。 Java 中是否有 httplib2.Http(disable_ssl_certificate_validation=True).request(...) 的等价物？

这是我尝试过的

String rawData = "search='search index=my_index'";
System.out.println(rawData);
String encodedData = URLEncoder.encode( rawData, "UTF-8" );
String name = "user";
String password = "pwd";
String authString = name + ":" + password;
System.out.println("auth string: " + authString);
byte[] authEncBytes = Base64.encodeBase64(authString.getBytes());
String authStringEnc = new String(authEncBytes);
URL u = new URL("https://localhost:8000/services/search/jobs");
HttpURLConnection conn = (HttpURLConnection) u.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Authorization", "Basic " + authStringEnc);
conn.setRequestProperty("Content-Type", "application/json; utf-8");
conn.setRequestProperty( "Content-Length", String.valueOf(encodedData.length()));
InputStream is = conn.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
int code = conn.getResponseCode();
System.out.println("Response    (Code):" + code);
System.out.println("Response (Message):" + conn.getResponseMessage());
DataInputStream input = new DataInputStream(conn.getInputStream());
int c;
StringBuilder resultBuf = new StringBuilder();
while ((c = input.read()) != -1) {
  resultBuf.append((char) c);
}
input.close();
System.out.print(resultBuf.toString());**/

我已经能够使用 Jsoup 来满足我的大部分 http 需求（主要是网页抓取）。

这是一些代码，用于发布我从 javacodeexamples.com 提取的事件

https://www.javacodeexamples.com/jsoup-post-form-data-example/822

Response response = 
                Jsoup.connect("http://www.example.com/postpage")
                .userAgent("Mozilla/5.0")
                .timeout(10 * 1000)
                .method(Method.POST)
                .data("txtloginid", "YOUR_LOGINID")
                .data("txtloginpassword", "YOUR_PASSWORD")
                .data("random", "123342343")
                .data("task", "login")
                .data("destination", "/welcome")
                .followRedirects(true)
                .execute();
