我正在制作Android游戏,有代码可以将高分信息发送到我的网站的PHP代码。
奇怪的是,这在Unity编辑器中运行良好,但是在我制作了一个.apk并在真正的Android手机上运行之后,它就无法运行并且会出错。
错误如下(Eclipse logcat已知)
05-05 22:56:47.997:I / Unity(20561):NullReferenceException:Object 引用未设置为对象的实例05-05 22:56:47.997: I / Unity(20561):at HighScore.GetHash(System.String usedString) [0x00000] in:0 05-05 22:56:47.997:I / Unity(20561): 在HighScore + c__Iterator14.MoveNext()[0x00000] in :0
代码是首次运行高分时注册昵称的功能。
public IEnumerator RegisterName(string name)
{
string finalResult = "";
string tables = "";
for (int m = 0; m < difficultyModes.Length; m++)
{//Create a list of tables to send
if (m < difficultyModes.Length - 1)
{
tables += difficultyModes[m].databaseName + " ";
}
else
{
tables += difficultyModes[m].databaseName;
}
}
WWWForm rsFm = new WWWForm();
rsFm.AddField("name", name);
rsFm.AddField("tables", tables);
rsFm.AddField("hash", GetHash(name));
WWW rs = new WWW(registerUserURL, rsFm);
yield return rs;
Debug.Log(rs.text + " : " + difficultyModes[modeIndex].displayName);
finalResult = rs.text;
if (finalResult.Equals("Already Used"))
{
runningHsServer = 0;
status = "Name Already Used";
TitleScript.Instance.PopupMsgWithNoBack("Name is already taken.", true);
yield break;
}
else if (finalResult.Equals("Registration Complete"))
{//We Registered Now Update Score
PlayerPrefs.SetInt("nameRegistered", 1);
PlayerPrefs.SetString("registeredName", name);
TitleScript.Instance.PopupMsgWithNoBack("Name registered!", true);
TitleScript.Instance.PopupNo();
NewUI.Instance.myNick.text = name;
myNickName = name;
NewUI.Instance.OpenHigh();
}
else
{
runningHsServer = 0;
status = finalResult; yield break;
}
}
和GetHash部分。 (此处出现NullReference错误)
string GetHash(string usedString)
{ //Create a Hash to send to server
MD5 md5 = MD5.Create();
//byte[] bytes = Encoding.ASCII.GetBytes(usedString+secretKey); // this wrong because can't receive korean character
byte[] bytes = Encoding.UTF8.GetBytes(usedString + secretKey);
byte[] hash = md5.ComputeHash(bytes);
StringBuilder sb = new StringBuilder();
for (int i = 0; i < hash.Length; i++)
{
sb.Append(hash[i].ToString("x2"));
}
return sb.ToString();
}
答案 0 :(得分:5)
使用MD5CryptoServiceProvider
代替MD5.Create()
var md5 = new MD5CryptoServiceProvider();
当Stripping Level设置为Micro mscorlib时,MD5.Create()不会在Unity Android上返回对象,但是'new MD5CryptoServiceProvider()'。
答案 1 :(得分:0)
所以这是因为统一构建设置的剥离级别设置。
最初我设置了最大的strippied设置(使用micro mscorlib)来获得更小的.apk文件大小,但这阻止了一些代码功能。
所以我把它设置为Disabled,上面的功能也可以在Android手机上正常工作。
