flask 上传文件

采用wtf 上传文件

设置表单：

class Up_file_Foem(FlaskForm):    body = FileField(u'选择上传文件', validators=[Required()])    submit = SubmitField(u'开始上传')

设置前端页面

@main.route('/', methods=['GET', 'POST'])  # def index():    form = Up_file_Foem()    print os.path.dirname(__file__)    if form.validate_on_submit():        file = form.body.data        # filename = secure_filename(file.filename) #判断文件名合法   但是当遇到中文时会导致文件名只剩后缀        filename = form.body.data.filename        file.save(os.path.join(os.path.dirname(__file__), filename))#file是文件流 save(所要保存文件的直接路径)        print '文件保存成功'    else:        print '---------------'    return render_template('index.html', form=form)

前端页面

    {% extends "base.html" %}{% import "bootstrap/wtf.html" as wtf %}{% import "_macros.html" as macros %}{% block title %}首页{% endblock %}{% block page_content %}<div class="page-header">    <h1>欢迎</h1></div><div>    {{ wtf.quick_form(form) }}</div>{% endblock %}{% block scripts %}{% endblock %}

django 上传文件

html 表单提交

<form enctype="multipart/form-data" method="POST" action="http://10.10.10.242:5000/EasyNode/v1/NODE/conversion_kvm/">    <input type="text" name="a"> <br>    <input type="file" name="myfile" /><br>   <br />   <input type="submit" value="上传文件" /></form>

后台获取：

if request.method == 'POST':    myFile = request.FILES.get("myfile", None)    print request.POST['a']    if os.path.exists(file_path + '/' + myFile.name):  # 判断文件是否重名        File_name = time.strftime('%Y_%m_%d', time.localtime(time.time())) + myFile.name    else:        File_name = myFile.name    if not myFile:        return HttpResponse(simplejson.dumps({'code': 1,'msg':'name repeat'}))    try:        destination = open(os.path.join(file_path, File_name), 'wb+')  # 保存文件        for chunk in myFile.chunks():  # 分块写入文件            destination.write(chunk)        destination.close()    except:        HttpResponse(simplejson.dumps({'code': 2,'msg':'save file erro'}))    return HttpResponse(simplejson.dumps({'code': 0}))
