ColdFusion OpenCSV打开内存中的文件

Question

想象一下你需要动态解析的一种CSV文件.

它适用于本地磁盘存储,但不适用于ram:///

<cfscript>

cfhttp(
    method = "Get",
    url = "http://real-chart.finance.yahoo.com/table.csv?s=YHOO&d=4&e=2&f=2016&g=d&a=3&b=12&c=2016&ignore=.csv",
    //path = "C:\CFTemp",
    path = "ram:///",
    file = "currentCSV.csv"
);

cfdirectory(
    name="files",
    action="list",
    directory="ram:///",
    recurse="true",
    type="all"
);
writeDump(files);

myfile = FileRead("ram:///currentCSV.csv");
WriteOutput("#myfile#");


fileReader = createobject("java","java.io.FileReader");
fileReader.init("ram:///currentCSV.csv");  // -ERROR

csvReader = createObject("java","com.opencsv.CSVReader");
csvReader.init(fileReader, ",");
ArrayData = csvReader.readAll();
writeDump(ArrayData);

</cfscript>

-ERR ram:/currentCSV.csv(文件名,目录名或卷标语法不正确)

这里有什么问题？

ColdFusion 11,OpenCSV 3.7

Answer 1

VFS或"ram:///"是仅适用于ColdFusion函数的CF构造. FileReader是一个对VFS一无所知的java类.AFAIK,它的构造函数只接受标准文件路径,即c:/path/file.txt.
