httpClient 没有配置 SSL 会出现如下错误
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

}发送测试
BasicHeader[] basicHeaders = new BasicHeader[1];
basicHeaders[0] = new BasicHeader("Content-Type","application/json");
String res = sendPost.postData(tokenApi, jsonObject.toString(),basicHeaders);里面有很多方法都是废弃的，不建议使用，后面再改吧。
