注意几点：
1、参数传递的+号处理，在传输时会把+变成空格，不处理后端就报错了。
1、前端代码
<!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Login</title> <script src="/UploadFiles/2021-04-02/jquery-1.10.2.min.js">2、后端代码
public class IndexController : Controller { public ActionResult Login() { return View(); } [HttpPost] public ActionResult Login(string pwd) { //密钥格式要生成pkcs#1格式的 而不是pkcs#8格式的 string privateKey = @"MIICWwIBAAKBgQCa4KHNwDX44gGmmIAtRu4gjVYtGWZzcm4t+1wjUD4dn7fMLPvuK7ai4UrfDeEJE1RPwudJw+lJ6crql8wSIg7/DbTlG3ihsCT6dT9H5B9OoeR7K9VW UesaW/iyVL6HXiYOANabW14pvJATDmdq91Tfgp6PSQyvdfiRdV4r07crpQIDAQAB AoGABb+3gdb+qeG0b1CogVsT/7//UOaTzPk/FGneKQQTf4SsN+H7lVhTYTG9ARFC JyoWg8IXqmn2ljhywHPTWWD2RCZIn2sYT1sVkGb70EgHGQLBraFHElmw+DsVJ+nD fBCfMrJ1TYXlwigjRkaueaoGgG8LdR8XD+Xs5LersPLjZgECQQCguSB7C4wF6oSw EDmwNF8ffT5cQc1U2OIq6NBG8rafrjb7LsjhOd03pmY7i4LbW3Vvq4AhQpJEdF1C vd+Sk/BBAkEA9rBhqnyumV09zFEomSX3zZu+bdhTzM4bJDfEa95swp1gANCVvF/t DCnlBf51EhCWdeGSpARPUkQnXrYfFUDiZQJAAZEshuaa6+fYeVr/JP+tucHf3Mhr dxtSQTbZ6QcuzqnFMXfIT6HfzU4bCxOWKAthPsB+VFSw1mgIDMGLL4OvwQJAJlVy V9PYLezXVZCnBmVoBINXLCqZmxHMFey0kS6XKAbcjEPdgNBHPcSk2jGYb540Q00y RFqHGPmORKF4Yw0aIQJAd5JRtD3z2MgP/vPoKHJNHqY8bboVcmwqVAm6xCZoTCZz jNV1Cnsdf4wBV3LCDzYBy+xR4qYNUy5CFXN+8WzzAA=="; try { RSACryptoServiceProvider rsaCryptoServiceProvider = CreateRsaProviderFromPrivateKey(privateKey); //把+号，再替换回来 byte[] res = rsaCryptoServiceProvider.Decrypt(Convert.FromBase64String(pwd.Replace("%2B","+")), false); return Content(Encoding.UTF8.GetString(res)); } catch (Exception exception) { } return Content(""); } private RSACryptoServiceProvider CreateRsaProviderFromPrivateKey(string privateKey) { var privateKeyBits = System.Convert.FromBase64String(privateKey); var RSA = new RSACryptoServiceProvider(); var RSAparams = new RSAParameters(); using (BinaryReader binr = new BinaryReader(new MemoryStream(privateKeyBits))) { byte bt = 0; ushort twobytes = 0; twobytes = binr.ReadUInt16(); if (twobytes == 0x8130) binr.ReadByte(); else if (twobytes == 0x8230) binr.ReadInt16(); else throw new Exception("Unexpected value read binr.ReadUInt16()"); twobytes = binr.ReadUInt16(); if (twobytes != 0x0102) throw new Exception("Unexpected version"); bt = binr.ReadByte(); if (bt != 0x00) throw new Exception("Unexpected value read binr.ReadByte()"); RSAparams.Modulus = binr.ReadBytes(GetIntegerSize(binr)); RSAparams.Exponent = binr.ReadBytes(GetIntegerSize(binr)); RSAparams.D = binr.ReadBytes(GetIntegerSize(binr)); RSAparams.P = binr.ReadBytes(GetIntegerSize(binr)); RSAparams.Q = binr.ReadBytes(GetIntegerSize(binr)); RSAparams.DP = binr.ReadBytes(GetIntegerSize(binr)); RSAparams.DQ = binr.ReadBytes(GetIntegerSize(binr)); RSAparams.InverseQ = binr.ReadBytes(GetIntegerSize(binr)); } RSA.ImportParameters(RSAparams); return RSA; } private int GetIntegerSize(BinaryReader binr) { byte bt = 0; byte lowbyte = 0x00; byte highbyte = 0x00; int count = 0; bt = binr.ReadByte(); if (bt != 0x02) return 0; bt = binr.ReadByte(); if (bt == 0x81) count = binr.ReadByte(); else if (bt == 0x82) { highbyte = binr.ReadByte(); lowbyte = binr.ReadByte(); byte[] modint = { lowbyte, highbyte, 0x00, 0x00 }; count = BitConverter.ToInt32(modint, 0); } else { count = bt; } while (binr.ReadByte() == 0x00) { count -= 1; } binr.BaseStream.Seek(-1, SeekOrigin.Current); return count; } }总结

P70系列延期，华为新旗舰将在下月发布
3月20日消息，近期博主@数码闲聊站 透露，原定三月份发布的华为新旗舰P70系列延期发布，预计4月份上市。
而博主@定焦数码 爆料，华为的P70系列在定位上已经超过了Mate60，成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢？
根据目前爆料的消息来看，华为P70系列将推出三个版本，其中P70和P70 Pro采用了三角形的摄像头模组设计，而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智，但辨识度绝对拉满。
