在Android業(yè)務(wù)開發(fā)中，抓包/mock數(shù)據(jù)一般有兩種方案（該篇主要介紹第二種方案）：

一、通過Charles(或fiddle)抓包/mock數(shù)據(jù)：

二、添加Intercepter來抓取/mock數(shù)據(jù)：

前提：

網(wǎng)絡(luò)庫使用的是okhttp或Retrofit。

這里就用到了okhttp框架的原理定義一個MockDataInterceptor【Mock數(shù)據(jù)攔截器】，并在創(chuàng)建Builder實例的時候直接使用addIntercepter【應(yīng)用攔截器】添加MockDataInterceptor實例即可：

1、addInterceptor(new MockDataInterceptor())：

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.connectTimeout(15, TimeUnit.SECONDS)
       .readTimeout(15, TimeUnit.SECONDS)
       .writeTimeout(15, TimeUnit.SECONDS)
       //在此處添加MockDataInterceptor攔截即可
       .addInterceptor(new MockDataInterceptor())
       .retryOnConnectionFailure(false);

?2、MockDataInterceptor定義如下:

/**
 * Mock數(shù)據(jù)攔截器
 */
public class MockDataInterceptor implements Interceptor {

    private static final String TAG = "MockDataInterceptor";
    //是否開啟mock數(shù)據(jù)
    private static final boolean mockIsOpen = true;
    private String path;

    private static Map<String, String> pathMap;

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        Response response = chain.proceed(request);
        Headers headers = response.request().headers();
        if (shouldInterceptorRequest(request) && mockIsOpen) {
            //查看Headers請求參數(shù)
            Log.d(TAG, "headers:" + headers);

            //查看原始responseBody數(shù)據(jù)
            Response.Builder builder = response.newBuilder();
            if (response.body() != null) {
                String originalBody = response.body().string();
                Log.d(TAG, "原始的 responseBody：" + originalBody);
            }

            if (!TextUtils.isEmpty(getMockData())) {
                //為responseBody賦值[mock數(shù)據(jù)]
                ResponseBody responseBody = ResponseBody.create(MediaType.parse("application/json; charset=utf-8"), getMockData());
                builder.body(responseBody);
                Log.d(TAG, "mock數(shù)據(jù)后 responseBody:" + getMockData());
            }
            return builder.build();
        } else {
            return response;
        }
    }

    //獲取對應(yīng)的mock數(shù)據(jù)
    private String getMockData() {
        for (String key : pathMap.keySet()) {
            if (path.contains(key)) {
                return pathMap.get(key);
            }
        }
        return "";
    }

    //在此處添加被攔截的接口判斷
    private boolean shouldInterceptorRequest(Request request) {
        path = request.url().url().getPath();

        for (String key : pathMap.keySet()) {
            if (path.contains(key)) {
                Log.d(TAG, "path:" + path);
                return true;
            }
        }
        return false;
    }


    public static final String MOCK_DATA_APP_***_*HECK = "{\n" +
            "    \"resMsg\":{\n" +
            "        \"code\":0,\n" +
            "        \"message\":\"\\u6210\\u529f\"\n" +
            "    },\n" +
            "    \"datas\":{\n" +
            "        \"type\":1,\n" +
            "        \"title\":\"\標題",\n" +
            "        \"content\":\"哈哈哈",\n" +
            "        \"url\":\"\"\n" +
            "    }\n" +
            "}";

    //將對應(yīng)的接口path及該接口mock數(shù)據(jù)添加到pathMap中
    static {
        pathMap = new HashMap<>();
        pathMap.put("app****heck", MOCK_DATA_APP_***_*HECK);
    }
}

使用前需注意：

• mock開關(guān)是打開的mockIsOpen = true;
• pathMap中已添加所需的接口path及mock數(shù)據(jù)。

這樣就可以愉快的抓包及mock數(shù)據(jù)了。文章來源地址http://www.zghlxwxcb.cn/news/detail-727303.html
