我目前正在开发一个 woocommerce api，我需要使用改造来集成 api。该网站采用 HTTP，因此不能通过纯 HTTP 使用 HTTP 基本身份验证，因为 key 容易被拦截。 API 使用 OAuth 1.0a“单腿”身份验证来确保您的 API key 不会被拦截。我经历了this artical了解在 http 上使用哪种 OAuth 方法。

我已经使用 Scribe 成功实现了 api但我想使用改造来实现 api，谷歌搜索后我发现拦截器是 Jake Wharton Oauth1SigningInterceptor .

所以我在身份验证改造中实现了它，但是 api 调用返回了

{"code":"woocommerce_rest_cannot_view","message":"Sorry, you cannot list resources.","data":{"status":401}}

如果我使用 Scribe 调用相同的 api 返回成功的响应

下面是我调用Api的方式

BasicAuthInterceptor.java(修改自 jake wharton Oauth1SigningInterceptor)

public class BasicAuthInterceptor implements Interceptor {
private static final Escaper ESCAPER = UrlEscapers.urlFormParameterEscaper();

    this.consumerKey = consumerKey;
    this.consumerSecret = consumerSecret;

    this.random = random;
}
@Override

    return chain.proceed(signRequest(chain.request()));
}

public Request signRequest(Request request) throws IOException {

    String oauthNonce = ByteString.of(nonce).base64().replaceAll("\\W", "");
    String oauthTimestamp = String.valueOf(System.currentTimeMillis());

    String consumerKeyValue = ESCAPER.escape(consumerKey);


    SortedMap<String, String> parameters = new TreeMap<>();

                ESCAPER.escape(url.queryParameterValue(i)));
    }


    RequestBody requestBody = request.body();
    Buffer body = new Buffer();

    if (requestBody != null) {
        requestBody.writeTo(body);

        String key = body.readUtf8(keyEnd);
        body.skip(1); // Equals.

        long valueEnd = body.indexOf((byte) '&');
        String value = valueEnd == -1 ? body.readUtf8() : body.readUtf8(valueEnd);
        if (valueEnd != -1) body.skip(1); // Ampersand.

        parameters.put(key, value);
    }

    Buffer base = new Buffer();
    String method = request.method();
    base.writeUtf8(method);
    base.writeByte('&');
    base.writeUtf8(ESCAPER.escape(request.url().newBuilder().query(null).build().toString()));
    base.writeByte('&');

    boolean first = true;
    for (Map.Entry<String, String> entry : parameters.entrySet()) {
        if (!first) base.writeUtf8(ESCAPER.escape("&"));
        first = false;
        base.writeUtf8(ESCAPER.escape(entry.getKey()));
        base.writeUtf8(ESCAPER.escape("="));

    }

    String signingKey =
            ESCAPER.escape(consumerSecret);// + "&" + ESCAPER.escape(accessSecret);

    SecretKeySpec keySpec = new SecretKeySpec(signingKey.getBytes(), "HmacSHA1");
    Mac mac;
    try {
        mac = Mac.getInstance("HmacSHA1");
        mac.init(keySpec);
    } catch (NoSuchAlgorithmException | InvalidKeyException e) {
        throw new IllegalStateException(e);
    }
    byte[] result = mac.doFinal(base.readByteArray());
    String signature = ByteString.of(result).base64();

    String authorization = "OAuth "
            + OAUTH_CONSUMER_KEY + "=\"" + consumerKeyValue + "\", "

    Log.d("message","--"+authorization);


    return request.newBuilder()
            .addHeader("Authorization", authorization)

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

    }
}
}

远程 API 调用

public final class RemoteApiCalls {
private static final String TAG = "RemoteApiCalls";

public static final class Builder {
    RemoteRetrofitInterfaces mService;
    Retrofit mRetrofit;

    public Builder remoteApiCall(String url,Context mContext) {
        return remoteApiCall(mContext,url, 40, 40, 40);
    }

    BasicAuthInterceptor oauth1 = new BasicAuthInterceptor.Builder()
            .consumerKey("keyhere")//i have added keys
            .consumerSecret("secert here")//i have added secertkeys
            .build();

    public Builder remoteApiCall(Context mContext, String url, int connectionTimeout, int readTimeout, int writeTimeout) {

         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(oauth1)
                .build();

        mRetrofit = new Retrofit.Builder()
                .baseUrl(url).addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build();
        mService = mRetrofit.create(RemoteRetrofitInterfaces.class);


        return this;
    }



    public void getProductCatogry()

    {

        Call<ProductCategoryResponse> mApiCall = mService.getListCategory();
        mApiCall.enqueue(new Callback<ProductCategoryResponse>() {
            @Override
            public void onResponse(Call<ProductCategoryResponse> call, Response<ProductCategoryResponse> response) {

                if (response.isSuccessful()) {


                } else {

                }
            }

            @Override
            public void onFailure(Call<ProductCategoryResponse> call, Throwable t) {
t.printStackTrace();
            }


        });

    }

}

}

RemoteRetrofitInterfaces.java

public interface RemoteRetrofitInterfaces {

@GET("products")
Call<ProductCategoryResponse> getListCategory();
}

在我调用的主 Activity 中

 new RemoteApiCalls.Builder().remoteApiCall("http://mywebsite.com/wp-json/wc/v1/",getApplicationContext()).getProductCatogry();

仍然收到 401 错误

{"code":"woocommerce_rest_cannot_view","message":"Sorry, you cannot list resources.","data":{"status":401}}

使用的 Woo commerce 版本是 2.6.4 版 API版本为v1

任何人都可以帮助我解决这个问题我想通过改造本身来实现它。

最佳答案

最后我找到了解决方案希望这对其他人有帮助

我浏览各种文件

1) Using the WooCommerce REST API – Introduction

2) woocommerce-rest-api-docs

3) Scribe

4) scribe:1.3.5

在引用了上述文档和源代码之后，我最终创建了一个库，它为 woocommerce HTTP android 执行 OAuth 1.0a“单腿”身份验证

完整的描述已添加到我的图书馆的自述部分
