Answer 1

可能需要修改此代码..

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            httpclient.execute(httppost);
            cnt++;
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();

两次使用httpclient.execute（）可能是数据被插入两次的可能原因。

像这样修改你的代码..

   httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// httpclient.execute(httppost);
   cnt++;
   HttpResponse response = httpclient.execute(httppost);
   HttpEntity entity = response.getEntity();

实际上这种类型的问题一般都是我面临的浏览器问题...... 要修复它，您可以尝试编辑.htaccess以防止在浏览器请求时重定向到索引文件我猜你的查询运行正常，但在服务器中部署时会出现问题为了避免这种情况，请在启动时将其添加到您的php文件中，

if(strpos($_SERVER['HTTP_USER_AGENT'],'Mediapartners-Google') !== false) {
        exit();
    }

这可以帮到你
