下面提供二种方法会使用java发送url请求，并获取服务器返回的值
第一种方法：
代码如下:
import org.apache.http.HttpEntity
import org.apache.http.HttpResponse
import org.apache.http.NameValuePair
import org.apache.http.client.HttpClient
import org.apache.http.client.entity.UrlEncodedFormEntity
import org.apache.http.client.methods.HttpPost
import org.apache.http.impl.client.DefaultHttpClient
import org.apache.http.message.BasicNameValuePair
import org.apache.http.params.CoreConnectionPNames
import org.apache.http.util.EntityUtils
publicstaticStringsendUrlRequest(StringurlStr,Stringparam1,Stringparam2)throwsException{
StringtempStr=null
HttpClienthttpclient=newDefaultHttpClient()
Propertiesproperties=newProperties()
HttpEntityentity=null
StringxmlContent=""
try
{
//设置超时时间
httpclient.getParams().setIntParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,20000)
httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,20000)
//封装需要传递的参数
List<NameValuePair>nvps=newArrayList<NameValuePair>()
nvps.add(newBasicNameValuePair("mainMemoCode",strmainMemoCode))
nvps.add(newBasicNameValuePair("recordPassWord",strrecordPassWord))
//客户端的请求方法类型
HttpPosthttpPost=newHttpPost(urlStr)
httpPost.setEntity(newUrlEncodedFormEntity(nvps,"GBK"))
HttpResponseresponse=httpclient.execute(httpPost)
//获取服务器返回Http的Content-Type的值
tempStr=response.getHeaders("Content-Type")[0].getValue().toString()
//获取服务器返回页面的值
entity=response.getEntity()
xmlContent=EntityUtils.toString(entity)
Stringstrmessage=null
System.out.println(xmlContent)
System.out.println(response.getHeaders("Content-Type")[0].getValue().toString())
httpPost.abort()
}
catch(SocketTimeoutExceptione)
{
}
catch(Exceptionex)
{
ex.printStackTrace()
}
finally{
httpclient.getConnectionManager().shutdown()
}
第二种方法：
代码如下:
publicstaticStringsendUrlRequest(StringurlStr,Stringparam1,Stringparam2)throwsException{
HttpURLConnectionurl_con=null
try{
URLurl=newURL(urlStr)
StringBufferbankXmlBuffer=newStringBuffer()
//创建URL连接，提交到数据，获取返回结果
HttpURLConnectionconnection=(HttpURLConnection)url.openConnection()
connection.setRequestMethod("POST")
connection.setDoOutput(true)
connection.setRequestProperty("User-Agent","directclient")
PrintWriterout=newPrintWriter(newOutputStreamWriter(connection.getOutputStream(),"GBK"))
out.println(param)
out.close()
BufferedReaderin=newBufferedReader(newInputStreamReader(connection
.getInputStream(),"GBK"))
StringinputLine
while((inputLine=in.readLine())!=null){
bankXmlBuffer.append(inputLine)
}
in.close()
tempStr=bankXmlBuffer.toString()
}
catch(Exceptione)
{
System.out.println("发送GET请求出现异常！"+e)
e.printStackTrace()
}finally{
if(url_con!=null)
url_con.disconnect()
}
returntmpeStr
}
总结：多练习代码，熟练之后才能更快速的去了解代码的学习的方法。多去获取一些思维方面的书籍可以看看。
// 如果得到项目中的文件路径 统一资源定位符 通过文件名获取文件的绝对路径URL url = Prop2.class.getResource("/a.properties") //import java.net.URL
System.out.println(url.getPath())
