用django统计代码行数+注释行数

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"),
]
