如何使用oAuth1进行改造呼叫？

Question

我有一个Wordpress网站，我想使用API​​将其连接到android应用程序，但该API不是公开的，因此我在网站上创建了一个用户，并获得了用户密钥和消费者秘密。 现在，我想使用此信息对API端点进行Retrofit调用。

我找到了一些文档，并按照文档进行了实现，但是我仍然从Retrofit得到空响应。

1。这里是我如何建立改造连接

public class RetrofitConnection {
    private static RetrofitConnection mInstance;
    private static final String BASE_URL = "https://www.example.net/wp-json/wp/v2/";
    private Retrofit mRetrofit;

    private RetrofitConnection() {
        String consumerKey    = "***"; //api key
        String consumerSecret = "***"; //api secret

        OAuthInterceptor oauth1Woocommerce = new OAuthInterceptor.Builder()
                .consumerKey(consumerKey)
                .consumerSecret(consumerSecret)
                .build();

        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder()
                .connectTimeout(20, TimeUnit.SECONDS)
                .writeTimeout(20, TimeUnit.SECONDS)
                .readTimeout(30, TimeUnit.SECONDS)
                .addInterceptor(interceptor)
                .addInterceptor(oauth1Woocommerce)// Interceptor oauth1Woocommerce added
                .build();
        mRetrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build();
    }

    public static RetrofitConnection getInstance() {
        if (mInstance == null) {
            mInstance = new RetrofitConnection();
        }
        return mInstance;
    }

    public JobiumApi getJSONApi() {
        return mRetrofit.create(JobiumApi.class);
    }
}

2。我在文档中创建的OAuthInterceptor

public class OAuthInterceptor implements Interceptor {


private static final String OAUTH_CONSUMER_KEY = "oauth_consumer_key";
private static final String OAUTH_NONCE = "oauth_nonce";
private static final String OAUTH_SIGNATURE = "oauth_signature";
private static final String OAUTH_SIGNATURE_METHOD = "oauth_signature_method";
private static final String OAUTH_SIGNATURE_METHOD_VALUE = "HMAC-SHA1";
private static final String OAUTH_TIMESTAMP = "oauth_timestamp";
private static final String OAUTH_VERSION = "oauth_version";
private static final String OAUTH_VERSION_VALUE = "1.0";

private final String consumerKey;
private final String consumerSecret;


private OAuthInterceptor(String consumerKey, String consumerSecret) {
    this.consumerKey = consumerKey;
    this.consumerSecret = consumerSecret;
}

@Override
public Response intercept(Chain chain) throws IOException {
    Request original = chain.request();
    HttpUrl originalHttpUrl = original.url();

    Log.d("URL", original.url().toString());
    Log.d("URL", original.url().scheme());
    Log.d("encodedpath", original.url().encodedPath());
    Log.d("query", ""+original.url().query());
    Log.d("path", ""+original.url().host());
    Log.d("encodedQuery", ""+original.url().encodedQuery());
    ;
    Log.d("method", ""+original.method());

    ////////////////////////////////////////////////////////////

    final String nonce = new TimestampServiceImpl().getNonce();
    final String timestamp = new TimestampServiceImpl().getTimestampInSeconds();
    Log.d("nonce", nonce);
    Log.d("time", timestamp);

    String dynamicStructureUrl = original.url().scheme() + "://" + original.url().host() + original.url().encodedPath();

    Log.d("ENCODED PATH", ""+dynamicStructureUrl);
    String firstBaseString = original.method() + "&" + urlEncoded(dynamicStructureUrl);
    Log.d("firstBaseString", firstBaseString);
    String generatedBaseString = "";


    if(original.url().encodedQuery()!=null) {
        generatedBaseString = original.url().encodedQuery() + "&oauth_consumer_key=" + consumerKey + "&oauth_nonce=" + nonce + "&oauth_signature_method=HMAC-SHA1&oauth_timestamp=" + timestamp + "&oauth_version=1.0";
    }
    else
    {
        generatedBaseString = "oauth_consumer_key=" + consumerKey + "&oauth_nonce=" + nonce + "&oauth_signature_method=HMAC-SHA1&oauth_timestamp=" + timestamp + "&oauth_version=1.0";

    }

    ParameterList result = new ParameterList();
    result.addQuerystring(generatedBaseString);
    generatedBaseString=result.sort().asOauthBaseString();
    Log.d("Sorted","00--"+result.sort().asOauthBaseString());

    String secoundBaseString = "&" + generatedBaseString;

    if (firstBaseString.contains("%3F")) {
        Log.d("iff","yess iff");
        secoundBaseString = "%26" + urlEncoded(generatedBaseString);
    }

    String baseString = firstBaseString + secoundBaseString;

    String signature = new HMACSha1SignatureService().getSignature(baseString, consumerSecret, "");
    Log.d("Signature", signature);

    HttpUrl url = originalHttpUrl.newBuilder()

            .addQueryParameter(OAUTH_SIGNATURE_METHOD, OAUTH_SIGNATURE_METHOD_VALUE)
            .addQueryParameter(OAUTH_CONSUMER_KEY, consumerKey)
            .addQueryParameter(OAUTH_VERSION, OAUTH_VERSION_VALUE)
            .addQueryParameter(OAUTH_TIMESTAMP, timestamp)
            .addQueryParameter(OAUTH_NONCE, nonce)
            .addQueryParameter(OAUTH_SIGNATURE, signature)


            .build();

    // Request customization: add request headers
    Request.Builder requestBuilder = original.newBuilder()
            .url(url);

    Request request = requestBuilder.build();
    return chain.proceed(request);
}


public static final class Builder {

    private String consumerKey;
    private String consumerSecret;
    private int type;

    public Builder consumerKey(String consumerKey) {
        if (consumerKey == null) throw new NullPointerException("consumerKey = null");
        this.consumerKey = consumerKey;
        return this;
    }

    public Builder consumerSecret(String consumerSecret) {
        if (consumerSecret == null) throw new NullPointerException("consumerSecret = null");
        this.consumerSecret = consumerSecret;
        return this;
    }



    public OAuthInterceptor build() {

        if (consumerKey == null) throw new IllegalStateException("consumerKey not set");
        if (consumerSecret == null) throw new IllegalStateException("consumerSecret not set");

        return new OAuthInterceptor(consumerKey, consumerSecret);
    }
}

public String urlEncoded(String url) {
    String encodedurl = "";
    try {

        encodedurl = URLEncoder.encode(url, "UTF-8");
        Log.d("TEST", encodedurl);
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();

    return encodedurl;
}
