本文介绍了Auth 1.0 oauth_signature创建用于magento API的Android的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用以下Autherization作为标题调用Magento API，
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，获取错误oauth_problem=signature_invalid.所有其他参数均成功验证，但签名中出现错误，我尝试使用以下代码来生成签名，
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);
}
我将oauth_consumer_secret和oauth_token_secret作为参数传递给签名.但是它仍然会得到同样的错误.
如何在android中生成签名以及我需要传递哪个值才能获得相同的签名?
解决方案
我们不需要将所有属性都作为auth传递，对其进行改造本身就可以了，我们只需要传递CONSUMER_KEY，CONSUMER_SECRET，ACCESS_TOKEN和TOKEN_SECRET. /p>
通过此
ApiUtils类就像
科特林
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)
}
}
}
Android 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);
}
}
以及 RetrofitClient类
科特林
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
}
}
}
Android 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;
}
}
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=*******************) ;
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);
}
I pass the oauth_consumer_secret and oauth_token_secret as the parameter to get signature . But its still get the same error.
How to generate the signature in android and which value I need to pass to get the same?
解决方案
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.
By following this
ApiUtils class will be like,
Kotlin
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)
}
}
}
Android 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);
}
}
and for RetrofitClient Class
Kotlin
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
}
}
}
Android 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;
}
}
