Auth 1.0 oauth_signature 创建Android for magento API [英] Auth 1.0 oauth_signature creation Android for magento API

问题描述

我使用以下身份验证作为标头调用 Magento API，

I call the Magento API with the following Autherization as header,

auth = "OAuth oauth_consumer_key=**********************,oauth_consumer_secret=****************,oauth_token=************,oauth_token_secret=**************,oauth_signature_method=HMAC-SHA1,oauth_timestamp=" + ConstantFunctions.GetTimeStamp() + ",oauth_nonce=" + ConstantFunctions.GetNonce() + ",oauth_signature=*******************) ;

当我调用 API 时，出现错误 oauth_problem=signature_invalid .所有其他参数验证成功，但在签名中出现错误，我尝试使用以下代码生成签名，

While I call the API, Getting error oauth_problem=signature_invalid .All other parameters validate successfully but got an error in the signature, I try the following code to generate the signature,

     public static String GETHMACSHA1(String value, String key)
            throws UnsupportedEncodingException, NoSuchAlgorithmException,
            InvalidKeyException {
        String type = "HmacSHA1";
        SecretKeySpec secret = new SecretKeySpec(key.getBytes(), type);
        Mac mac = Mac.getInstance(type);
        mac.init(secret);
        byte[] bytes = mac.doFinal(value.getBytes());
        return bytesToHex(bytes);
    }

    private final static char[] hexArray = "0123456789abcdef".toCharArray();

    private static String bytesToHex(byte[] bytes) {
        char[] hexChars = new char[bytes.length * 2];
        int v;
        for (int j = 0; j < bytes.length; j++) {
            v = bytes[j] & 0xFF;
            hexChars[j * 2] = hexArray[v >>> 4];
            hexChars[j * 2 + 1] = hexArray[v & 0x0F];
        }
        return new String(hexChars);
    }

我通过 oauth_consumer_secret 和 oauth_token_secret 作为参数来获取签名.但它仍然得到同样的错误.

I pass the oauth_consumer_secret and oauth_token_secret as the parameter to get signature . But its still get the same error.

如何在android中生成签名以及我需要传递哪个值才能得到相同的值?

How to generate the signature in android and which value I need to pass to get the same?

推荐答案

我们不需要把所有的属性都作为 auth 传递，retrofit 自己处理这个，我们只需要传递 CONSUMER_KEY、CONSUMER_SECRET、ACCESS_TOKEN 和 TOKEN_SECRET.

We didn't need to pass all the attribute as auth, retrofit itself handle this, we need to pass only the CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN and TOKEN_SECRET.

通过关注this

ApiUtils 类将类似于，

class ApiUtils {
companion object {
    fun getAPIService(): APIService? {
        val consumer = OkHttpOAuthConsumer(BuildConfig.CONSUMER_KEY, BuildConfig.CONSUMER_SECRET)
        consumer.setTokenWithSecret(BuildConfig.ACCESS_TOKEN, BuildConfig.TOKEN_SECRET)
        return RetrofitClient.getClient(BuildConfig.BASE_URL, consumer)?.create(APIService::class.java)
    }
}

}

public class ApiUtils {

    private ApiUtils() {
    }

    private static final String BASE_URL = BuildConfig.BASE_URL;

    public static APIService getAPIService() {

        OkHttpOAuthConsumer consumer = new OkHttpOAuthConsumer(BuildConfig.CONSUMER_KEY, BuildConfig.CONSUMER_SECRET);
        consumer.setTokenWithSecret(BuildConfig.ACCESS_TOKEN, BuildConfig.TOKEN_SECRET);

        OkHttpClient client = new OkHttpClient.Builder()
                .addInterceptor(new SigningInterceptor(consumer))
                .build();
        return RetrofitClient.getClient(BASE_URL, client).create(APIService.class);
    }
}

和 RetrofitClient 类

    class RetrofitClient {
    companion object {
        private var retrofit: Retrofit? = null
        private val gSON = GsonBuilder()
            .setLenient()
            .create()

        fun getClient(baseUrl: String, consumer: OkHttpOAuthConsumer): Retrofit? {
            val logging = HttpLoggingInterceptor()
            if (BuildConfig.DEBUG) {
                logging.level = HttpLoggingInterceptor.Level.BODY
            } else {
                logging.level = HttpLoggingInterceptor.Level.NONE
            }

            val httpClient = OkHttpClient.Builder()
            httpClient.connectTimeout(60000, TimeUnit.SECONDS)
            httpClient.writeTimeout(120000, TimeUnit.SECONDS)
            httpClient.readTimeout(120000, TimeUnit.SECONDS)
            httpClient.retryOnConnectionFailure(true)
            httpClient.addInterceptor(SigningInterceptor(consumer))
            httpClient.addInterceptor { chain ->
                val request = chain.request()
                val requestBuilder = request.newBuilder()
                    .header(HEADER_CONTENT_TYPE_KEY, PreferenceHandler.getContentType())
                    .header(HEADER_ACCEPT_KEY, PreferenceHandler.getAcceptType())
                    .header(HEADER_CACHE_CONTROL_KEY, PreferenceHandler.getCacheControl())
                val modifiedRequest = requestBuilder.build()
                chain.proceed(modifiedRequest)
            }

            httpClient.addNetworkInterceptor(logging)

            if (retrofit == null) {
                retrofit = Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .addConverterFactory(GsonConverterFactory.create(gSON))
                    .client(httpClient.build())
                    .build()
            }
            return retrofit
        }

    }
}

安卓 java

public class RetrofitClient {

    private static Retrofit retrofit = null;

    public static Retrofit getClient(String baseUrl,OkHttpClient client) {
        if (retrofit == null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(baseUrl)
                    .client(client)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }
        return retrofit;
    }
}
