arrays - Solidity 中字符串到数组的转换

Question

在 Solidity 中，有没有一种方法可以使用分隔符将字符串文本转换为数组，以识别字符串中的复合部分

示例

mystring = "This-Is-A-Problem";

至

myArray = [This,Is,A,Problem];   // using hyphen as separator

import "github.com/Arachnid/solidity-stringutils/strings.sol";

contract Contract {                                                            
    using strings for *;                                                       

    function smt() public pure {                                               
        strings.slice memory s = "This-Is-A-Problem".toSlice();                
        strings.slice memory delim = "-".toSlice();                            
        string[] memory parts = new string[](s.count(delim));                  
        for (uint i = 0; i < parts.length; i++) {                              
           parts[i] = s.split(delim).toString();                               
        }                                                                      
    }
