没有证书认证的，如果想访问支付宝等，需要配置一个访问的公钥
public class HttpClient {

private String charset = "UTF-8";

private boolean safe = false;

private String url;

Map<String, String> headers = null;

public HttpClient(String url) {
this.url = url;

...

public String post(String httpStr) throws IOException {
if (this.safe) {
return this.sendhttpsReq("POST", "", headers);

.....
while ((byteread = in.read(buf)) != -1) {
result.append(buf, 0, byteread);
}
....
conn.setRequestMethod(method);
conn.setDoOutput(true);

}
});
conn.setRequestProperty("Content-Type", "text/html");
.....
}
StringBuilder result = new StringBuilder(100);

} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyManagementException e) {
e.printStackTrace();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return "";
}
