java - 如何用java创建hastebin

Question

我需要在java中创建一个hastebin粘贴，但我不知道如何做。我试过这个

public static String paste(String content) throws MalformedURLException, IOException {
        URL url = new URL("https://hasteb.in/documents");
        URLConnection con = url.openConnection();
        HttpURLConnection http = (HttpURLConnection) con;
        http.addRequestProperty("data", content);
        http.setRequestMethod("POST"); 
        http.setDoOutput(true);

        InputStream in = new BufferedInputStream(http.getInputStream());
        BufferedReader reader = new BufferedReader(new InputStreamReader(in));

        StringBuilder entirePage = new StringBuilder();
        String inputLine;
        while ((inputLine = reader.readLine()) != null) {
            entirePage.append(inputLine);
        }
        reader.close();
        if (!(entirePage.toString().contains("\"key\":\""))) {
            return "UNKNOWN";
        }
        return "https://hasteb.in/"+entirePage.toString().split("\"key\":\"")[1].split("\",")[0];
    }

但是它不起作用。错误是Caused by: java.lang.IllegalArgumentException: Illegal character(s) in message header value有什么帮助吗？

Answer 1

要使用 HttpURLConnection 执行 POST 请求，您需要使用提供的 OutputStream 功能编写请求正文，而不是设置名为“data”的 HTTP header :

try (OutputStream out = http.getOutputStream()) {
  out.write(content.getBytes());
  out.flush();
}

这需要在您开始从 InputStream 读取之前发生(我建议也使用 try-with-resources)。
