Post请求代码：

String url=String.format("https://api.weixin.qq.com/wxa/msg_sec_check?access_token=%s", access_token);
try {
    URIBuilder builder = new URIBuilder(url);
    URI uri = builder.build();
    HttpPost httpPost = new HttpPost(uri);
    StringEntity s = new StringEntity(content, "utf-8");
    s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
    httpPost.setEntity(s);
    httpPost.setHeader("Content-type", "application/json");
    response = httpclient.execute(httpPost);
    if (response.getStatusLine().getStatusCode() == 200) {
        resultString = EntityUtils.toString(response.getEntity(), "UTF-8");
    }
} catch (Exception e) {
    e.printStackTrace();
}

后台请求后获取到如下JSON：{"errcode":47001,"errmsg":"data format error hint: [T8SpSa04594711]"}

47001错误码没有在文档里找到 请大佬们指条路
