setSearchPaths的奇怪表现

admin 2018-3-27 156

这个问题一直没有解决，所以在此求解决方案

问题出现在android平台上调用cc.FileUtils:getInstance():setSearchPaths()函数，出现传入参数和getSearchPaths打印内容不一致(mac和iOS平台上没有问题),代码和打印结果如下:

lua层代码

 
logUtil:
write(
"+++++++setSearchPaths前的组数:+++++++"
)    
for
 
_
, sp 
in
 ipairs(searchPaths) 
do

        
logUtil:
write(sp)    
end


    
logUtil:
write(
"-----执行setSearchPaths-----"
)
    cc.
FileUtils
:getInstance
()
:setSearchPaths
(searchPaths)    
logUtil:
write(
"*****setSearchPaths后的组数:*****"
)    
for
 
_
, path 
in
 ipairs(cc.
FileUtils
:getInstance
()
:getSearchPaths
() ) 
do

        
if
 path ~= 
""
 
then

            
logUtil:
write(path..
">>>>>>"
..string.format(
"%s"
, tostring(cc.
FileUtils
:getInstance
()
:isDirectoryExist
(path))))        
end

    
end

打印结果：

从日志中可以看到执行setSearchPaths函数以前是

.../data/data/com.cuocuo.majiang/files/new_version/assets/src//data/data/com.cuocuo.majiang/files/new_version/assets/res/...
assets/src/assets/res/

执行setSearchPaths后变成了:

.../data/data/com.cuocuo.majiang/files/new_version/assets/res//data/data/com.cuocuo.majiang/files/new_version/assets/res/...
assets/res/assets/res/

C++层的代码如下：

void
 FileUtils::setSearchPaths(
const
 
std
::
vector
<
std
::
string
>& searchPaths)
{    
bool
 existDefaultRootPath = 
false
;

    _fullPathCache.clear();
_searchPathArray.clear();
for
 (
const
 
auto
& iter : searchPaths)
{    
std
::
string
 prefix;    
std
::
string
 path;    
if
 (!isAbsolutePath(iter))
    { 
// Not an absolute path

        prefix = _defaultResRootPath;
    }
    path = prefix + (iter);    
if
 (path.length() > 
0
 && path[path.length()-
1
] != 
'/'
)
    {
        path += 
"/"
;
    }    
if
 (!existDefaultRootPath && path == _defaultResRootPath)
    {
        existDefaultRootPath = 
true
;
    }
    _searchPathArray.push_back(path);
}
if
 (!existDefaultRootPath)
{    
//CCLOG("Default root path doesn't exist, adding it.");

    _searchPathArray.push_back(_defaultResRootPath);
}
}
