Question

尝试使用POST方法从API获取数据。并返回

线程中的异常＆＃34; main＆＃34; javax.net.ssl.SSLHandshakeException： sun.security.validator.ValidatorException：PKIX路径构建失败： sun.security.provider.certpath.SunCertPathBuilderException：无法找到所请求目标的有效证书路径

我已经考虑过修复它，但所有答案都非常模糊，它与Installcert有关，但没有在线有指示。我无法弄明白，因为我在编程方面相对较新。任何帮助将非常感谢

 public static void main(String[] args) throws Exception {


    URL url = new URL("https://probasketballapi.com/stats/players");
    Map<String,Object> params = new LinkedHashMap<>();
    params.put("api_key", "8Z9zCply76uBnEDF3itvshqJOPd4Rjoe");
    params.put("first_name", "Kevin");
    params.put("last_name", "Durant");

    StringBuilder postData = new StringBuilder();
    for (Map.Entry<String,Object> param : params.entrySet()) {
        if (postData.length() != 0) postData.append('&');
        postData.append(URLEncoder.encode(param.getKey(), "UTF-8"));
        postData.append('=');
        postData.append(URLEncoder.encode(String.valueOf(param.getValue()), "UTF-8"));
    }
    byte[] postDataBytes = postData.toString().getBytes("UTF-8");

    HttpURLConnection conn = (HttpURLConnection)url.openConnection();
    conn.setRequestMethod("POST");
    conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
    conn.setRequestProperty("Content-Length", String.valueOf(postDataBytes.length));
    conn.setDoOutput(true);
    conn.getOutputStream().write(postDataBytes);

    Reader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));

    for (int c; (c = in.read()) >= 0;)
        System.out.print((char)c);

Http Post方法。无法找到有效的目标认证路径
