            kk = parent_path

    if check_repo_access_permission(repo_id, request.user) == 'rw':
        token = seafile_api.get_fileserver_access_token(repo_id, 'dummy',

        yy += '/'
    #yy2 = yy.encode('utf-8')
    return HttpResponse(json.dumps({"url": url,"path":yy}), content_type=content_type)

我加的代码如下


dir_name = request.GET.get('dir-structure')
parent_path = request.GET.get('path')
yy=''
if dir_name and dir_name != '':
    xx = dir_name.encode('utf-8')
    p,f=os.path.split(xx)
    yy=p

    cmmts = get_commits(repo_id, 0, 1)
    latest_commit = cmmts[0] if cmmts else None
    if not latest_commit:
        return ''
    dirents = seafile_api.list_dir_by_commit_and_path(repo_id, latest_commit.id,parent_path.encode('utf-8'))
    zz=[];
    if yy:
        zz = yy.split('/')
    xx=[]
    for x in dirents:
        xx.append(x.obj_name)
    if zz[0] not in xx:
        seafile_api.post_dir(repo_id, parent_path.encode('utf-8'),zz[0], username)
    if len(zz)>1:
        jj = len(zz)
        kk = parent_path
        for j in range(1,jj):
            kk += zz[j-1]+'/'
            #kk = parent_path+zz[j-1]+'/'
            dirents2 = seafile_api.list_dir_by_commit_and_path(repo_id, latest_commit.id,kk)
            uu=[]
            for d in dirents2:
                uu.append(d.obj_name.encode('utf-8'))
            if zz[j]: 
                if zz[j] not in uu:
                    seafile_api.post_dir(repo_id,kk,zz[j],username)

我做的是文件夹上传，当我的目录为英文的时候没有问题
但是当我的目录名字为中文的时候就出现问题，
程序卡在

    if zz[0] not in xx:
        seafile_api.post_dir(repo_id, parent_path.encode('utf-8'),zz[0], username)

这里了
这段代码前后打印yy，后面yy比前面yy的值要少
是不是中文字符串的问题，not in 这里没有问题吧

中文名字的文件夹，我打印传过来的文件夹名（encode utf-8之后）显示的是正常的中文。


            try:
        if len(zz)>1:
            jj = len(zz)
            kk = parent_path
            for j in range(1,jj):
                kk += zz[j-1]+'/'
                #kk = parent_path+zz[j-1]+'/'
                dirents2 = seafile_api.list_dir_by_commit_and_path(repo_id, latest_commit.id,kk)
                uu=[]
                for d in dirents2:
                    uu.append(d.obj_name.encode('utf-8'))
                if zz[j]: 
                    if zz[j] not in uu:
                        seafile_api.post_dir(repo_id,kk,zz[j],username)
    except Exception,e:
        f=open('/root/Desktop/out2.txt','a')
        print >>f,e
        f.close()
