python中文字符串编码的应用？

    content_type = 'application/json; charset=utf-8'

    op_type = request.GET.get('op_type') # value can be 'upload', 'update', 'upload-blks', 'update-blks'
    if not op_type:
        err_msg = _(u'Argument missing')
        return HttpResponse(json.dumps({"error": err_msg}), status=400,
                            content_type=content_type)

    username = request.user.username

        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:

            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=[]

    if check_repo_access_permission(repo_id, request.user) == 'rw':
        token = seafile_api.get_fileserver_access_token(repo_id, 'dummy',
                                                        op_type, username)
        url = gen_file_upload_url(token, op_type + '-aj')

    #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()
        

因为我上传的文件有多层目录，第一层目录中的文件上传成功，内层没有完全上传成功。
目录结构如下

Answer 1

你这里编码转换用的不对

Answer 2

import sys
reload(sys)
sys.setdefaultencoding('utf8')
