如何从网页源代码中找到文献原始数据库

知网代码部分，一模一样肯定是检测的，而且百分之百检测。

知网检测，就是用一定的算法将你的论文和知网数据库中已收录的论文进行对比，从而得出你论文中哪些部分涉嫌抄袭。目前的对比库有：

中国学术期刊网络出版总库

中国博士学位论文全文数据库/中国优秀硕士学位论文全文数据库

中国重要会议论文全文数据库

如何找到网站源码中的数据库

MDB数据库的，直接查看源码中的配置文件，查看数据库的位置和名称。

而用SQL之类数据库，请根据说明文件找数据库文件，添加到SQL服务器上。

高分求c#网页数据保存：保存网页内容到数据库中 代码

这个保存数据到数据库这里那你会不会了，会的话就请看下面，不会的话那就去学下这个ADO.NET这个最基本的知识点.

protected string getHtml(string url)

{

HttpWebRequest webRequest = null;

HttpWebResponse webResponse = null;

StreamReader streamReader = null;

string content=string.Empty;

try

{

webRequest = (HttpWebRequest)WebRequest.Create(url);

webRequest.Method = "GET";

webResponse = (HttpWebResponse)webRequest.GetResponse();

Stream stream = webResponse.GetResponseStream();

streamReader = new StreamReader(stream, System.Text.Encoding.GetEncoding("GB2312"));

content = streamReader.ReadToEnd();

}

catch

{

throw;

}

finally

{

streamReader.Close();

webResponse.Close();

}

return content;

}

protected void Button1_Click(object sender, EventArgs e)

{

string url = this.TextBox1.Text.Trim();

Response.Write(getHtml(url));

}

记得导入命名空间System.Net;System.IO;

这样通过按钮操作就可以读取某个网址的的HTML代码。返回的是一个string字符串类型！

然后就可以保存到数据库了！

Java 从网页抽取数据 存入数据库

台风的编号和名称直接在源码中有，但时间和地理位置我只能跟踪到

function totf(tfbh){

location.href( "Typhoon.aspx?id="+tfbh);

}

数据需要从aspx中拿到的，应该是存放到数据库的，页面上是拿不到的

我认为可以通过循环模拟发送请求Typhoon.aspx?id="+XXX，然后通过解析response包的方式可以获得详细的信息

下面一个页面是讲模拟发送请求的

希望对你有帮助

我写了一段获得一组数据的代码

//get Typhoon content by param

public static String getTyphoon(String param) {

URL url = null;

try {

url = new URL(param);

} catch (MalformedURLException e) {

e.printStackTrace();

}

HttpURLConnection connection = null;

InputStream is = null;

try {

connection = (HttpURLConnection) url.openConnection();

is = connection.getInputStream();

} catch (IOException e) {

e.printStackTrace();

}

BufferedInputStream bis = new BufferedInputStream(is);

int len = 0;

byte[] buf_all = new byte[0];

try {

while (true) {

byte[] buf1 = new byte[4096];

byte[] buf2 = buf_all;

len = bis.read(buf1);

if(len = 0){

break;

}

buf_all = new byte[len+buf2.length];

System.arraycopy(buf2, 0, buf_all, 0, buf2.length);

System.arraycopy(buf1, 0, buf_all, buf2.length, len);

}

} catch (IOException e) {

e.printStackTrace();

}

String content = null;

try {

content = new String(buf_all, "utf-8");

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

}

int startIndex = content.indexOf("var ary0=")+9;

content = content.substring(startIndex);

int endIndex = content.indexOf("var aryyb0=");

content = content.substring(0, endIndex);

return content;

}

得到的结果是这样的：

再下去字符串的拆分实在是太复杂了，不想写了

使用时只要参数为

id后是台风的代码号，写一个循环就可以了

怎样从HTML网页中获取SQL数据库里的数据

1、sudo su postgres指令进入postgres。

2、\c test\dt\d首先查看一下有的表格。

3、准备好sql文件。

4、SELECT * FROM person先查看一下表格的内容。

5、\i /home/coffee/Downloads/person.sql导入文件，如果出现错误，没关系，继续往下看。

6、DROP TABLE person;如果不想要表格，可以这样删除。再导入一次。

如何下载别人网站源码对接自己数据库

在百度里面搜索“asp源码”，免费的网站空间都支持asp开发的网站。在搜索页中点击进入网站，找到一个自己喜欢的网站源码并下载。下载完之后就可以解压了。
