Python批量发送post请求的实现代码

时间:2021-02-18 00:16     来源/作者:脚本之家

昨天学了一天的Python(我的生产语言是java,也可以写一些shell脚本,算有一点点基础),今天有一个应用场景,就正好练手了。

这个功能之前再java里写过,比较粗糙,原来是在我本机跑的,今天老大要求要随时保持请求,就用Python改写了下,省的又把一个有跟多杂项的jar包传到服务器,省空间又不乱,而且好读。

先附上java代码:

package xxxxxx.base; 
import java.util.Random;

  public static void main(String[] args) {

        int sleep = r.nextInt(1200000) + 600000;
        Thread.sleep(sleep);
        post();

        e.printStackTrace();
      }
    }
  }
   
  public static void post(){
    String url = "http://111.111.111.111:8080/xxxx/post";
     
    int[] types = {1, 2, 3, 4};
    int index = (int) (Math.random() * types.length);
    int type = types[index];
     
//   String[] contents = {"-中文测试-,","-English Test-,","~!@#$%^&*()_;:'-\"<>?/|\\-,","     "};
    String[] contents = {"-中文测试-,","-English Test-,","~!@#$%,","     "};
     
    StringBuffer content = new StringBuffer();
    content.append("haojianxiang test:");
    for (int i = 0; i < 10; i++) {
      int idx = (int) (Math.random() * contents.length);
      content.append(contents[idx]);
    }
     
    String[] imgs = {"/Upload/appUpload/58c7b315cb39f.jpg",
        "/Upload/appUploa/58cb467a69873.jpg",
        "/Upload/appUpload/58afff0e99432.png",
        "/Upload/appUpload/58b545539eb80.jpg",
        "/Upload/appUpload/58b55d7c9e281.JPG",
    };
    StringBuffer img = new StringBuffer();
     
    for (int i = 0; i < (int) (Math.random() * 4); i++) {
      int lucky = (int) (Math.random() * 2);
      if (lucky == 1) {
        int idx = (int) (Math.random() * imgs.length);
        img.append(imgs[idx]);
        img.append(",");
      }
    }
    String imgStr = "";
    if (StringUtils.isNotBlank(img)) {
      imgStr = img.substring(0, img.length()-1);
    }
    String param = "{\"req\":{\"userId\":xxxxxx}," +
        "\"data\":{"\"fbType\":" + type + ",\"fbContent\":\""+content.toString()+
        "\",\"fbPic\":\""+imgStr+"\"}}";
    String rst = HttpRequest.sendPost(url, param);
    System.out.println("TIME--"+ System.currentTimeMillis() + " result:" + rst);
  }
 
}

(代码里的参数地址等我已做了隐藏,json格式可能不准确了,无所谓)

接下来上Python代码:

  type = int(random.uniform(1,5))
  contents = ["-中文测试-,","-English Test-,","~!@#$%,","   "]
  content = "haojianxiang test:"
  for i in range(0,10):
    content += random.choice(contents)
 
  img = ""
  imgs = ["/Upload/58c7b315cb39f.jpg",

  for i in range(0,3):
    lucky = int(random.uniform(0,2))
    if lucky == 1:
      img += random.choice(imgs)
      img += ","
  img = img[:-1]
  data = "{\"req\":{\"userId\": xxx},"
  data += "\"data\":{
  data += "\"fbType\":"
  data += str(type)
  data += ",\"fbContent\":\""
  data += content
  data += "\",\"fbPic\":\""
  data += img
  data += "\"}}"
 
  pdata = bytes(data,encoding="utf-8")
  f = urllib.request.urlopen(url,pdata)
 
  result = f.read()
  result = result.decode('UTF-8')
  print(result)
 
if __name__ == "__main__":
  while True:
    st = int(random.uniform(600,1800))
    print("sleep:",st)
    time.sleep(st)
    postFeedBack()

Python的写法确实很简洁高效(java代码里post的逻辑,我还是调用了自己的一个工具类,实际代码要更多),今后打算把Python作为优先脚本语言,处理简单问题很快。
