我从“parse.com”检索了一个“ParseFile”。但是，我无法找到读取该“ParseFile”的正确方法。我尝试使用Java的“BufferReader”读取parseFile只是为了结束徒劳无功。
下面发布的是我的代码
final ParseQuery<ParseObject> query = ParseQuery.getQuery("TestObject");
query.getInBackground("xxxxxxxxx", new GetCallback<ParseObject>() {
public void done(ParseObject object, ParseException e) {
if (e == null) {
try {
ParseFile parseFile=object.getParseFile("file");
BufferedReader br = new BufferedReader(new FileReader(String.valueOf(parseFile)));
StringBuilder sb = new StringBuilder();
String line = br.readLine();
while (line != null) {
sb.append(line);
sb.append("\n");
line = br.readLine();
}
System.out.println("exact values"+sb.toString());
br.close(); }
catch (Exception e1) {
e1.printStackTrace();
}
} else {
System.out.println("bye!!");
}
}
});
下面发布的是我的 StackTrace:

FilenotFound Exception 行指向:
BufferedReader br = new BufferedReader(new FileReader(String.valueOf(parseFile)));
任何建议都会非常有帮助。 谢谢!
最佳答案
您正在将对象 parseFile 的字符串而不是文件传递给 FileReader。
换行
BufferedReader br = new BufferedReader(new FileReader(String.valueOf(parseFile)));
到
BufferedReader br = new BufferedReader(new FileReader(parseFile.getFile()));
