mel里,当要eval("client()"),并且要传递stirngarray参数给函数client()时,正确的写法应该是:
global proc intermediator_good(string $array[])
{
print(">intermediator(): ["+stringArrayToString($array, ",")+"], size="+size($array)+"
");
if( size($array) == 0 ){
$cmd = "client({})";
}else{
$cmd = "client({""+stringArrayToString($array,"", "")+""})";
}
eval $cmd;
}
要命的是,如果误写成:
global proc intermediator(string $array[])
{
print(">intermediator(): ["+stringArrayToString($array, ",")+"], size="+size($array)+"
");
$cmd = "client({""+stringArrayToString($array,"", "")+""})
";
eval $cmd;
}
在client()里:
global proc client(string $array[])
{
print(">client(): ["+stringArrayToString($array, ",")+"]
");
}
对于$array={""}和$array={}两种情况,print出来的信息是一样的(都是[])。调试的时候会被误导
