1.创建工程temp，同时创建app应用song01app

2.在创建的app应用song01app下创建文件目录"templates"——》"song01app"——》"upload_file.html"

3.在创建的app应用song01app下创建urls.py文件

4.在工程temp下的settings.py文件下添加应用名song01app

5.编写temp下的urls.py文件

[code]from django.contrib import admin
from django.urls import path, include

urlpatterns = [
path('admin/', admin.site.urls),
path('temp/', include('song01app.urls'))
]

6.编写应用song01app下的urls.py文件

[code]from django.urls import path
from song01app import views

urlpatterns = [
path('upload/', views.upload_file)
]

7.在应用song01app下创建monkey_log_file目录，用于存放上传的日志文件

8.编写upload_file.html

[code]<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>MonkeyTest</title>
</head>
<body>
<form method="post" action="" enctype="multipart/form-data">
{% csrf_token %}
<h1>Monkey 测试</h1>
请输入测试执行人：<input type="text" name="peoples">
请输入测试版本：<input type="text" name="versions"><br>
请上传monkey日志文件<input type="file" name="files"><br>
<input type="submit" value="上传">
<br>
<b><small>测试执行结果：</small></b><hr>
</form>
<table border="1">
<thead>
<tr>
<td>ID</td>
<td>测试执行人</td>
<td>测试版本号</td>
<td>ANR异常数</td>
<td>Crash异常数</td>
<td>Exception异常数</td>
<td>是否执行完</td>
<td>统计合计</td>
<td>备注</td>
</tr>
</thead>
<tbody>

</tbody>
</table>

</body>
</html>

8.编辑song01app下的views.py文件

[code]from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.
def upload_file(request):
if request.method == "POST":
File = request.FILES.get("files", None)
if File is None:
return HttpResponse("请选择需要上传的monkey日志文件")
else:
with open("./song01app/monkey_log_file/%s" % File.name, 'wb+') as  f:
for chunk in File.chunks():
f.write(chunk)
return render(request, "song01app/upload_file.html")
else:
return render(request, "song01app/upload_file.html")

9.编辑song01app应用下的models.py文件

[code]from django.db import models

# Create your models here.
class result(models.Model):
id = models.AutoField(primary_key=True)
name = models.CharField(max_length=150, blank=False, help_text='测试执行人')
version_num = models.PositiveIntegerField(blank=False,  help_text='版本号')
anr_num = models.IntegerField(blank=True,  help_text='ANR异常数')
crash_num = models.IntegerField(blank=True,  help_text='crash异常数')
exception_num = models.IntegerField(blank=True,  help_text='exception异常数')
monkey_is_finish = models.BooleanField(default=False, help_text='是否正常结束')
bug_num = models.IntegerField(blank=True, null=False, help_text='bug数量')
remark = models.CharField(max_length=30, blank=False, null=False, help_text="备注")

10.在应用song01app下创建一个num_count.py文件，用于处理文件中的数据

[code]def _out_log(request):
contains = json.loads(_open_andreadfile(request))
people = request.POST.get("peoples", None)
version = request.POST.get("versions", None)
if contains:
models.result.objects.create(bug_num=contains['total'], anr_num=contains['anr'],
crash_num=contains['crash'], exception_num=contains['exception'], monkey_is_finish=contains['is_finish'],
name=people, version_num=version, remark="写死到备注")
list = models.result.objects.all()
return list
else:
models.result.objects.create(bug_num=contains['total'], anr_num=contains['anr'],
crash_num=contains['crash'], exception_num=contains['exception'],monkey_is_finish=contains['is_finish'],
name=people, version_num=version, remark="写死到备注")

def _open_andreadfile(request):
File = request.FILES.get("files", None)
log_out_str = "./song01app/monkey_log_file/" + File.name
log_content = open(log_out_str, "r")
s = log_content.read()
anr = s.count('ANR')
crash = s.count('CRASH')
exception = s.count('Exception')
monkey_is_finish = s.count('Monkey finished')
total = anr+crash+exception
is_finish = False
if (monkey_is_finish > 0):
is_finish = True
log_content.close()
_result_list = json.dumps({'anr': anr, 'crash': crash, 'exception': exception, 'is_finish': is_finish, 'total': total})
return  _result_list

11.修改views.py和upload_file.html文件标红的地方，图1是views.py图2是upload_file.html

代码如下：

[code]return render(request, "song01app/upload_file.html", {"data": _out_log(request).all()})

[code]{% for result in data %}
<tr>
<td>{{ result.id}}</td>
<td>{{ result.name }}</td>
<td>{{ result.version_num }}</td>
<td>{{ result.anr_num}}</td>
<td>{{ result.crash_num }}</td>
<td>{{ result.exception_num }}</td>
<td>{{ result.monkey_is_finish }}</td>
<td>{{ result.bug_num }}</td>
<td>{{ result.remark}}</td>
</tr>
{% endfor %}

12.执行数据库迁移，在终端输入以下两条命令

13.重新启动服务

14.服务器启动成功后在浏览器输入http://127.0.0.1:8000/temp/upload/，自己填写信息上传文档试一下

15.运行上传后的结果如下：
