Django读取EXcel

前端重要代码　

<div class="row">
    <div>
        <form action="" method="post" enctype="multipart/form-data">
            <input type="file" name="file_obj">
            <!--  <input type="text" name="project_pk" hidden value="{{ project_pk }}">  -->
            <input type="submit" value="提交">
        </form>
        <span style="color: red">{{ error }}</span>
    </div>
</div>
{% endblock %}

重点是form表前要有enctype="multipart/form-data"字段标识，不然Django后台无法识别这个是文件类型的数据；上传文件的input字段的type类型要是file类型。
再来看views视图处理：

from django.shortcuts import render, redirect, HttpResponse
from django.db import transaction
def import_case(request, pk):
    """ 导入Excel数据，pk是所属项目的pk """
    if request.method == 'POST':
        try:
            with transaction.atomic():   # 事物
                # project_pk = request.POST.get("project_pk")  # 数据库使用字段
                excel = request.FILES.get('file_obj')
                book = xlrd.open_workbook(filename=None, file_contents=excel.read())
                sheet = book.sheet_by_index(0)
                title = sheet.row_values(0)
                for row in range(1, sheet.nrows):  
                    print(sheet.row_values(row))    # 这里取出来每行的数据，就可以写入到数据库了
                return HttpResponse('OK')
        except Exception as e:
            print(e)
            return render(request, 'import_case.html', {"project_pk": pk, "error": "上传文件类型有误，只支持 xls 和 xlsx 格式的 Excel文档"})

    return render(request, 'import_case.html', {"project_pk": pk, "error": ""})
