我有以下JSON字符串：
{"packedRecipeType":"DynamicCharacterAvatar","name":"Character","race":"HumanFemale","dna":[{"dnaType":"DynamicUMADna","dnaTypeHash":1932961400,"packedDna":"{\"bDnaAsset\":{\"instanceID\":108582},\"bDnaAssetName\":\"HumanFemaleDNA 1\",\"bDnaSettings\":[{\"name\":\"height\",\"value\":180},{\"name\":\"headSize\",\"value\":128},{\"name\":\"headWidth\",\"value\":57},{\"name\":\"neckThickness\",\"value\":128},{\"name\":\"armLength\",\"value\":128},{\"name\":\"forearmLength\",\"value\":128},{\"name\":\"armWidth\",\"value\":128},{\"name\":\"forearmWidth\",\"value\":128},{\"name\":\"handsSize\",\"value\":128},{\"name\":\"feetSize\",\"value\":128},{\"name\":\"legSeparation\",\"value\":128},{\"name\":\"upperMuscle\",\"value\":51},{\"name\":\"lowerMuscle\",\"value\":128},{\"name\":\"upperWeight\",\"value\":51},{\"name\":\"lowerWeight\",\"value\":128},{\"name\":\"legsSize\",\"value\":128},{\"name\":\"belly\",\"value\":128},{\"name\":\"waist\",\"value\":128},{\"name\":\"gluteusSize\",\"value\":128},{\"name\":\"earsSize\",\"value\":178},{\"name\":\"earsPosition\",\"value\":128},{\"name\":\"earsRotation\",\"value\":128},{\"name\":\"noseSize\",\"value\":96},{\"name\":\"noseCurve\",\"value\":115},{\"name\":\"noseWidth\",\"value\":102},{\"name\":\"noseInclination\",\"value\":128},{\"name\":\"nosePosition\",\"value\":134},{\"name\":\"nosePronounced\",\"value\":128},{\"name\":\"noseFlatten\",\"value\":134},{\"name\":\"chinSize\",\"value\":115},{\"name\":\"chinPronounced\",\"value\":134},{\"name\":\"chinPosition\",\"value\":204},{\"name\":\"mandibleSize\",\"value\":118},{\"name\":\"jawsSize\",\"value\":64},{\"name\":\"jawsPosition\",\"value\":137},{\"name\":\"cheekSize\",\"value\":96},{\"name\":\"cheekPosition\",\"value\":255},{\"name\":\"lowCheekPronounced\",\"value\":128},{\"name\":\"lowCheekPosition\",\"value\":255},{\"name\":\"foreheadSize\",\"value\":83},{\"name\":\"foreheadPosition\",\"value\":140},{\"name\":\"lipsSize\",\"value\":137},{\"name\":\"mouthSize\",\"value\":73},{\"name\":\"eyeRotation\",\"value\":124},{\"name\":\"eyeSize\",\"value\":121},{\"name\":\"breastSize\",\"value\":0},{\"name\":\"breastCleavage\",\"value\":149},{\"name\":\"eyeSpacing\",\"value\":150},{\"name\":\"green\",\"value\":214},{\"name\":\"red\",\"value\":255},{\"name\":\"blue\",\"value\":184}]}"}],"characterColors":[{"name":"Skin","colors":[197,118,90,255,0,0,0,0,255,255,255,255,0,0,0,0,255,255,255,255,0,0,0,0]},{"name":"Hair","colors":[84,71,57,255,0,0,0,0,255,255,255,255,0,0,0,0,255,255,255,255,0,0,0,0]},{"name":"Eyes","colors":[183,216,225,255,0,0,0,0,255,255,255,255,0,0,0,0,255,255,255,255,0,0,0,0]},{"name":"Undies","colors":[255,255,255,255,0,0,0,0,255,255,255,255,0,0,0,0,255,255,255,255,0,0,0,0]}],"wardrobeSet":[{"slot":"Eyes","recipe":"CatEyeWard"},{"slot":"Ears","recipe":"M_Elf_Ears"},{"slot":"Underwear","recipe":"FemaleUndies2"},{"slot":"Hair","recipe":"FemaleHair1"},{"slot":"Eyebrows","recipe":"FEyebrow1"},{"slot":"Eyelashes","recipe":"Fem_Eyelash"},{"slot":"Face","recipe":"FFace2"}],"raceAnimatorController":"UltimateCharacterControllerDemo"}
如果我从文件中读取并以这种方式插入到postgreSQL：
public static void testwrite(NpgsqlConnection conn)
{
string acct = "account1";
string char_name = "character";
string dna = File.ReadAllText("./file.txt", Encoding.UTF8);
using (var cmd = new NpgsqlCommand())
{
cmd.CommandText = "INSERT INTO character_data (account_name, character_name, dna_and_equipment) VALUES (@p, @q, @r)";
cmd.Parameters.Add(new NpgsqlParameter("@p", acct));
cmd.Parameters.Add(new NpgsqlParameter("@q", char_name));
cmd.Parameters.Add(new NpgsqlParameter("@r", NpgsqlDbType.Json) { Value = dna });
cmd.Connection = conn;
cmd.ExecuteNonQuery();
}
}
一切正常。但是，如果我将字符串从Windows计算机发送到Linux服务器，并尝试通过以下方式从服务器插入同一计算机上的数据库：
public static IEnumerator Create_Char(string acct_name, string char_name, string DNA_wardrobe, Action<string> succ, Action<string> err)
{
string bad_register = "";
if (char_name.Length >= 15 || char_name.Length <= 3 || char_name.Any(char.IsDigit) || char_name.Any(char.IsSymbol) || char_name.Contains(" "))
{
bad_register = "Please choose an account name having between 4 and 14 characters, letters only.";
err(bad_register);
yield break;
}
else if (badwords.Any(w => char_name.Contains(w)) || char_name.Any(char.IsSymbol))
{
bad_register = "Please choose an appropriate character name.";
err(bad_register);
yield break;
}
else
{
using (var cmd = new NpgsqlCommand())
{
cmd.CommandText = "SELECT EXISTS (SELECT character_name FROM character_data WHERE character_name = @q)";
cmd.Parameters.Add(new NpgsqlParameter("@q", char_name));
using (var conn = new NpgsqlConnection(dbConnectionString))
{
conn.Open();
cmd.Connection = conn;
if (Convert.ToBoolean(cmd.ExecuteScalar()))
{
bad_register = "That character name is already chosen.";
err(bad_register);
conn.Close();
yield break;
}
else
{
bad_register = "";
cmd.CommandText = "INSERT INTO character_data (account_name, character_name, dna_and_equipment) VALUES (@n, @p, @q)";
cmd.Parameters.Add(new NpgsqlParameter("@n", acct_name));
cmd.Parameters.Add(new NpgsqlParameter("@p", char_name));
cmd.Parameters.Add(new NpgsqlParameter("@q", NpgsqlDbType.Json) { Value = DNA_wardrobe });
cmd.ExecuteNonQuery();
succ(bad_register);
conn.Close();
yield break;
}
}
}
}
}
我得到了NpgsqlException：错误：22P02：json类型的输入语法无效。现在，我知道我会遗漏很多东西，但是显然，我无法发布整个程序。如果您需要更多信息，请告诉我。
问题是，如果我将其保存到服务器上的文件中，然后将其转换为字节并从客户端发送并在服务器上接收，则可以使用从文件中读取并插入...的第一种方法。实际上，我什至执行了bash“ diff”命令来查看两个文件之间的差异，并且根本没有差异...我不明白为什么一个插入有效而另一个不起作用...唯一我能想到的是编码。这可能是错误的原因吗？ JSON字符串中是否有固有的东西可能导致此错误？可能还有别的东西，而我遗漏了一些相关信息吗？如果是这样，我会很乐意根据需要进行编辑和添加。
我在Ubuntu 18.04服务器上具有以下postgres软件包：postgresql-server-dev-10。 testwrite方法使用的是nuget中最新的Npgsql驱动程序，而协程Create_Char使用的是该驱动程序的Unity3d变体。
编辑：我应该提到JSON源自第三方。我已经联系过他们，他们声称它是有效的JSON，因为任何在线JSON验证程序都会同意。但是，我只是注意到了一些东西。对于每个双引号，都不存在字符串中用于避免双引号的许多斜杠。它给了我一个删除所有斜杠的想法，而且可以肯定的是，没有斜杠的JSON无效。
