本文讨论了如何在聊天服务器中实现用户头像上传功能，并通过采用Web服务器进行性能优化。包括模型定义、表单创建、视图处理及客户端上传代码。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

接着之前的聊天服务器

做上用户头像上传。

考虑到性能问题，头像资料修改这些采用web服务器来做

以下代码只是测试。

models.py

from django.db import models

class ChatUser(models.Model):

    uid = models.IntegerField(primary_key=True, db_index=True)

    username = models.CharField(max_length=64)

    password = models.CharField(max_length=64)

    sex = models.IntegerField(default=0)

    description = models.CharField(max_length = 256, blank=True, null=True)

    headphoto = models.ImageField(upload_to='photos/users/' , blank=True, null=True)

    class Meta:

        db_table    = 'user'

forms.py

from django.forms import ModelForm
from models import ChatUser

class UserForm(ModelForm):

    class Meta:
        model = ChatUser

        fields = ( 'username' , 'password' , 'sex' , 'description', 'headphoto')

views.py

@csrf_exempt
def index(request):

    c = {}

    if request.method == 'POST':

        form = UserForm(request.POST , request.FILES)

        if form.is_valid():

            username = form.cleaned_data['username']
            password = form.cleaned_data['password']

            user = ChatUser.objects.filter( username = username, password = password )
            if user:
                print 'userhead ' , user[0].headphoto
                path = settings.WEB_BASE_PATH + '/' + str(user[0].headphoto)
                print path
                import os
                try:
                    os.remove( path )
                except:
                    pass
                import Image
                uploaded = request.FILES['headphoto']
                from django.core.files.base import ContentFile
                file_content = ContentFile(uploaded.read())
                user[0].headphoto.save( str(user[0].headphoto), file_content )

            else:
                form.save()

            return HttpResponseRedirect('thanks.html')

        else:
            print 'error ' , form.errors

    else:

        form = UserForm(initial={'username':'watsy', 'password':'123123'})

    c['form'] = form

    return render_to_response('index.html', c)

iso客户端采用BeeFramework0.3版本,采用其他方式上传也可以

上传代码:

UIImage *image = [UIImage imageNamed:@"default_user_head"];
        
        self.HTTP_POST( @"http://127.0.0.1:8000" )
        .PARAM(@"username" , @"watsy")
        .PARAM(@"password" , @"123123")
        .PARAM(@"sex" , @"0")
        .FILE_ALIAS(@"watsy.jpg" , UIImageJPEGRepresentation(image, 1) , @"headphoto" );
