鸿蒙ArkTs使用axios发起网络请求并对请求参数加密

翛然dl2024-08-26 19:01

下载安装axios

shell 复制代码 
ohpm install @ohos/axios

需要权限

json5 复制代码 
{
  "module": {
    "requestPermissions": [
      {
        "name": "ohos.permission.INTERNET",
        "reason": "$string:permission_internet",
        "usedScene": {
          "abilities": [
            "EntryAbility"
          ],
          //inuse（使用时）、always（始终）。
          "when": "inuse"
        }
      }
    ]
  }
}

AES加密数据：

ts 复制代码 
  //参数排序后序列化
  let jsonParams: string = JSON.stringify(obj)
  Logger.debug(TAG, jsonParams)

  //生成aes秘钥
  //创建秘钥生成器
  let symKeyGenerator = cryptoFramework.createSymKeyGenerator('AES256')
  // 通过非对称密钥生成器，随机生成非对称密钥
  let promiseSymKey = symKeyGenerator.generateSymKeySync();
  //转换成可以读懂的字符串
  let key = buffer.from(promiseSymKey.getEncoded().data).toString('hex').substring(0, 32);

  //创建iv
  let iv = key.substring(0, 16);
  let ivParam: cryptoFramework.IvParamsSpec = {
    algName: 'IvParamsSpec',
    iv: {
      data: new Uint8Array(buffer.from(iv).buffer)
    }
  }

  //convertKey方法是通过秘钥生成symKey
  let symKey = symKeyGenerator.convertKeySync({ data: new Uint8Array(buffer.from(key).buffer) });

  //创建cipher
  let cipher = cryptoFramework.createCipher('AES256|CBC|PKCS7');

  //创建cipher之后才能初始化
  cipher.initSync(cryptoFramework.CryptoMode.ENCRYPT_MODE, symKey, ivParam);
  let output = cipher.doFinalSync({ data: new Uint8Array(buffer.from(jsonParams, 'utf-8').buffer) })
  let base64: util.Base64Helper = new util.Base64Helper();
  //加密后的数据
  let aesParams = base64.encodeToStringSync(output.data);

RSA加密数据：

extendtypescript 复制代码 
  //RSA加密aes秘钥
  //将公钥转换
  let symKeyBlob: crypto.DataBlob = { data: base64.decodeSync(PUBLIC_KEY) };
  let aesGenerator = crypto.createAsyKeyGenerator('RSA1024');
  let pubPair = aesGenerator.convertKeySync(symKeyBlob, null);
  //生成加密器
  let encoder = crypto.createCipher('RSA1024|PKCS1');
  //初始化加密环境
  encoder.initSync(crypto.CryptoMode.ENCRYPT_MODE, pubPair.pubKey, null);
  //封装加密所需数据
  let encode = new util.TextEncoder();
  //开始加密
  let updateOutput = encoder.doFinalSync({ data: encode.encodeInto(key) });
  //转换字符串
  let rsaKay = buffer.from(updateOutput.data).toString("base64");
  //写入请求头
  config.headers[CryptoConstant.PRIVATE_KEY] = rsaKay;
