在Retrofit中为不同的端点添加多个拦截器

Question

要为我的改造端点返回模拟JSON数据，我创建了一个自定义拦截器并将其添加到OkHttpClient进行Retrofit，如下所示：client.addInterceptor(new HttpInterceptor());

我创建的实现工作正常，但它的可扩展性不高。所有端点及其模拟数据都在一个文件中处理，如下所示：

public class HttpInterceptor implements Interceptor {
private static final int TEST_QUANTITY = 10;

@Override
public Response intercept(Chain chain) throws IOException {

    Response response;
    String responseString;
    String uriPath = chain.request().url().uri().getPath();
    if (uriPath.equalsIgnoreCase("/geofences")) {
        responseString = buildMockGeofences(TEST_QUANTITY);
    } else if (uriPath.equalsIgnoreCase("/retailers")) {
        responseString = buildMockRetailers(TEST_QUANTITY);
    } else if (uriPath.equalsIgnoreCase("/products")) {
        responseString = buildMockProducts(TEST_QUANTITY);
    } else if (uriPath.matches("/retailers/(\\d+)")) {
        String stringId = uriPath.replaceAll("[^0-9]", "");
        int id = Integer.parseInt(stringId);
        responseString = getRetailer(id);
    } else if (uriPath.matches("\\/products\\/\\w+")) {
            String id =  uriPath.substring(uriPath.lastIndexOf('/') + 1);
            responseString = getProduct(id);
    } else if (uriPath.matches("/geofences/(\\d+)")) {
        String stringId = uriPath.replaceAll("[^0-9]", "");
        int id = Integer.parseInt(stringId);
        responseString = getGeofence(id);
    } else {
        responseString = "{}";
    }
    response = new Response.Builder()
            .code(200)
            .message(responseString)
            .request(chain.request())
            .protocol(Protocol.HTTP_1_0)
            .body(ResponseBody.create(MediaType.parse("application/json"), responseString.getBytes()))
            .addHeader("content-type", "application/json")
            .build();
    return response;
}

private String buildMockProducts(int testQuantity) {
    String jsonProducts = "";
    for (int i = 1; i <= testQuantity; i++) {
        jsonProducts += "{\"_id\" : \" " + i + " \" , " +
                "\"name\" : \"Product" + i + "\" , " +

                "\"stickerId\" :  \"" + stickerIds().get(i) + "\"  }";
        if (i != testQuantity)
            jsonProducts += ",";
    }
    return "[" + jsonProducts + "]";
}

private List<String> stickerIds() {
    List<String> stickerIdList = new ArrayList<>();
    stickerIdList.add(null);
    stickerIdList.add("0798e8199c4fbbaa");

    return stickerIdList;
}

private String getProduct(String id) {
    return  "{\"_id\" : \" " + id + " \" , " +
            "\"name\" : \"Product\" , " +
            "\"category\" : \"category\" , " +

}


private String buildMockRetailers(int numberOfRetailers) {
    String jsonRetailers = "";
    for (int i = 1; i <= numberOfRetailers; i++) {
        jsonRetailers += "{\"_id\" : \" " + i + " \" , " +
                "\"name\" : \"Retailer Name " + i + "\" , " +

                "\"geofence\" :  \"" + i + "\"  }";
        if (i != numberOfRetailers)
            jsonRetailers += ","; // don't add closing comma
    }
    return "[" + jsonRetailers + "]";
}

private String getRetailer(int id) {
    return "[{\"_id\" : \" " + id + " \" , " +
            "\"name\" : \"Retailer Name " + id + "\" , " +
            "\"street\" : \"straatnaam\" , " +
            "\"housenumber\" : \" " + id + " \" , " +
            "\"postalCode\" : \"1023BH\" , " +
            "\"city\" : \"City\" , " +
            "\"geofence\" : \"" + id + "\" }]";
}

private String getGeofence(int id) {
    return "[{\"_id\" : \" " + id + " \" , " +
            "\"title\" : \"TEST_GEOFENCE" + id + "\" , " +
            "\"latitude\" : " + genRandLatitude() + " , " +

}

private String buildMockGeofences(int numberOfGeofences) {
    String jsonGeofences = "";
    for (int i = 1; i <= numberOfGeofences; i++) {
        jsonGeofences += "{\"_id\" : \"58ca9bc5384ec0172c94423" + i + "\" , " +

        if (i != numberOfGeofences)
            jsonGeofences += ",";
    }
    return "[" + jsonGeofences + "]";
}

private double genRandLatitude() {
    Random r = new Random();
    double randomValue = 52.322632 + (52.397274 - 52.322632) * r.nextDouble();
    return Math.floor(randomValue * 1000000) / 1000000;
}

private double genRandLongitude() {
    Random r = new Random();
    double randomValue = 4.845314 + (4.952431 - 4.845314) * r.nextDouble();
    return Math.floor(randomValue * 1000000) / 1000000;
}

如何在Retrofit的httpclient中添加多个拦截器？因为如果我只是分开这样的逻辑：

client.addInterceptor(new GeofenceHttpInterceptor()); client.addInterceptor(new RetailerHttpInterceptor()); client.addInterceptor(new ProductHttpInterceptor());

它仍将拦截第一个拦截器中的url。任何帮助都很高兴。
