实现统计代码行数：
1、首先在url.py中配置
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^upload/', views.upload), ]
2、写视图函数：实现统计代码的行数以及注释行数，其中以.py文件为例，注释是以“#”或者““”“”“””开头的，去掉空格
from django.shortcuts import render,redirect # Create your views here. def upload(request): if request.method == "POST": file_obj = request.FILES.get("file") with open(file_obj.name, "wb") as f: for chunk in file_obj.chunks(): f.write(chunk) # 已经将文件保存在服务端，现在开始进行代码统计 code_line = 0 comment_line = 0 flag = False with open(file_obj.name, "r", encoding="utf-8") as f2: for line in f2: if line.strip(): if flag and not line.strip().startswith('"""'): comment_line += 1 else: if line.strip().startswith("#"): comment_line += 1 elif line.strip().startswith('"""'): if not flag: flag = True else: flag = False comment_line += 1 else: code_line += 1 return render(request, "show.html", {"filename": file_obj.name, "code_line": code_line, "comment_line": comment_line}) return render(request, "upload.html")
3、写html代码：
upload.html的代码：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>上传代码</title> <link rel="stylesheet" href="/static/bootstrap-3.3.7/css/bootstrap.css"> </head> <body> <form action="" method="post" enctype="multipart/form-data"> {% csrf_token %} <div class="form-group" style="margin-top: 40px;margin-left: 200px;"> <input type="file" name="file" id="exampleInputFile"> </div> <button type="submit" class="btn btn-success" style="margin-left: 200px">提交</button> </form> </body> </html>
show.html的代码：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>代码数</title> </head> <body> <ul style="margin-left: 200px;margin-top: 40px;"> <li>文件名：{{filename}}</li> <li>代码行数：{{code_line}}</li> <li>注释行数：{{comment_line}}</li> </ul> </body> </html>
引入bootstrap样式的时候，一定要配置static：
STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static"), ]
