我有一个用分隔符分割字符串的函数:
function ExtractURL(url: string; pattern: string; delimiter: char): string;
var
indexMet, i: integer;
urlSplit: TArray<String>;
delimiterSet: array [0 .. 0] of char;
begin
delimiterSet[0] := delimiter;
urlSplit := url.Split(delimiterSet);
Result := '';
for i := 0 to Length(urlSplit) - 1 do
begin
if urlSplit[i].Contains(pattern) then
begin
indexMet := urlSplit[i].LastIndexOf('=') + 1; // extracts pairs key=value
Result := urlSplit[i].Substring(indexMet);
Exit;
end;
end;
end;
当分隔符是单个字符('&amp;','|')时,该函数可以正常工作。如何将换行符作为分隔符传递。我试过#13#10,'#13#10',sLineBreak,Chr(13)+ Chr(10),但它们不起作用。

@TLama首先评论这个问题解决了我的问题。我重写了这个功能:
function ExtractURL(url: string; pattern: string; delimiter: string): string;
var
indexMet, i: integer;
urlSplit: TStringDynArray;
begin
// note that the delimiter is a string, not a char
urlSplit := System.StrUtils.SplitString(url, delimiter);
result := '';
for i := 0 to Length(urlSplit) - 1 do
begin
if urlSplit[i].Contains(pattern) then
begin
indexMet := urlSplit[i].LastIndexOf('=') + 1;
result := urlSplit[i].Substring(indexMet);
Exit;
end;
end;
end;
