为了Python的自学党们,黑马真的是拼了!我们不仅有“人工智能+Python学习路线图”,还根据以往的经验,总结出学习Python之前的各种问题,想详细了解,从此贴开始吧!!!
Python都说效率高,1个Python工程师=2个PHP工程师=3个Java工程师,这个是什么意思 ?
service api的demo实现,里面有java,php和python三种实现,打开一看,被python这类脚本语言所折服,单从代码量上来说,差别实在是太大,如果都是熟手开发,业务场景也正好适合该语言的话,开发效率自然就不用再说: 扣除掉注释之后:java 56行;php:30行;python:15行
package com.test.http; import java.io.*; import java.net.HttpURLConnection; import java.net.URL; import java.security.MessageDigest; import java.math.BigInteger; public class ApiDemo{ public static void sendRequest(String id, String secureKey) throws IOException{ URL request = new URL("xxxxxx?id="+id); HttpURLConnection connection = (HttpURLConnection)request.openConnection(); connection.setDoOutput(true); connection.setDoInput(true); connection.setRequestMethod("POST"); connection.setUseCaches(false); connection.setInstanceFollowRedirects(true); connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); connection.connect(); String scanParam = "{\"scanlist\":[{\"sid\":\"123\", \"url\":\"http://dl.test.com/test.apk\", \"md5\":\"3d41f29d762ec547bfa4b42f57f3dc7c\"}]}"; String authKey = getStringMd5(scanParam + id + secureKey); String post = "authkey=" + authKey + "&request=" + scanParam; DataOutputStream writeStream = new DataOutputStream(connection.getOutputStream()); writeStream.writeBytes(post); writeStream.flush(); writeStream.close(); BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream())); String line=""; while ((line = reader.readLine()) != null){ System.out.println(line); } reader.close(); connection.disconnect(); } public static String getStringMd5(String src) { MessageDigest md; StringBuilder md5 = new StringBuilder(); try{ md = MessageDigest.getInstance("md5"); md.update(src.getBytes()); for (byte b : md.digest()) { md5.append(String.format("%02x", b)); } } catch (Exception e) { e.printStackTrace(); } return md5.toString(); } public static void main(String[] args) throws Exception { try { sendRequest("test", "123456"); } catch (IOException e) { e.printStackTrace(); } }
}
<?php
$id="test";
$secure_key="123456";
$api_url="http://xxxxx?id=".$id;
$scan_parm="{\"scanlist\":[{\"sid\":\"123\", \"url\":\"http://dl.test.com/test.apk\", \"md5\":\"3d41f29d762ec547bfa4b42f57f3dc7c\"}]}";
$authkey=md5($scan_parm.$id.$secure_key);
$post="authkey=".$authkey."&request=".$scan_parm;
$url_info=parse_url($api_url);
if(!isset($url_info["port"])){
$url_info["port"]=80;
}
$request.="POST ".$url_info["path"]."?".$url_info["query"]." HTTP/1.1\r\n";
$request.="Host: ".$url_info["host"]."\r\n";
$request.="Cache-Control: no-cache\r\n";
$request.="Content-type: application/x-www-form-urlencoded\r\n";
$request.="Accept: text/html\r\n";
$request.="Content-length: ".strlen($post)."\r\n";
$request.="Connection: close\r\n";
$request.="\r\n";
$request.=$post;
$fp = fsockopen($url_info["host"], $url_info["port"]);
if(!$fp){
echo "$errstr($errno)\n";
}
fwrite($fp, $request);
while(!feof($fp)){
$response .= fgets($fp, 128);
}
echo "$response\n";
?>
#!/usr/bin/python
import httplib, md5
if __name__ == "__main__":
id="test"
secure_key="123456"
scan_param='{"scanlist":[{"sid":"123", "url":"http://xxxxx/test.apk", "md5":"3d41f29d762ec547bfa4b42f57f3dc7c"}]}"'
authkey=md5.new(scan_param + id + secure_key).hexdigest()
post= "authkey=%s&request=%s" %(authkey, scan_param)
domain="xxxxx"
url_path = "/api/scansoft?id="+id
headers = {"Content-type": "application/x-www-form-urlencoded"}
connect = httplib.HTTPConnection(domain)
connect.request("POST", url_path, post, headers)
res = connect.getresponse()
print res.read()
所以,Python的开发效率极高。
