在java.lang.ClassNotFoundException的情况下使用dagger

我删除了

implementation("com.squareup.okhttp3:okhttp:4.9.0")

一切都很正常。

对于那些需要在Retrofit中进行高级日志记录的人，可以像这样使用拦截器

public static class LoggingInterceptor implements Interceptor {
    @Override public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        long t1 = System.nanoTime();
        String requestLog = String.format("Sending request %s on %s%n%s",
                request.url(), chain.connection(), request.headers());
        //YLog.d(String.format("Sending request %s on %s%n%s",
        //        request.url(), chain.connection(), request.headers()));
        if(request.method().compareToIgnoreCase("post")==0){
            requestLog ="\n"+requestLog+"\n"+bodyToString(request);
        }
        Log.d("TAG","request"+"\n"+requestLog);

        Response response = chain.proceed(request);
        long t2 = System.nanoTime();

        String responseLog = String.format("Received response for %s in %.1fms%n%s",
                response.request().url(), (t2 - t1) / 1e6d, response.headers());

        String bodyString = response.body().string();

        Log.d("TAG","response"+"\n"+responseLog+"\n"+bodyString);

        return response.newBuilder()
                .body(ResponseBody.create(response.body().contentType(), bodyString))
                .build();
        //return response;
    }
}

public static String bodyToString(final Request request) {
    try {
        final Request copy = request.newBuilder().build();
        final Buffer buffer = new Buffer();
        copy.body().writeTo(buffer);
        return buffer.readUtf8();
    } catch (final IOException e) {
        return "did not work";
    }
}`

嘿，伙计们，我已经找到解决方案了:

  public static <T> T createApi(Context context, Class<T> clazz, String host, boolean debug) {
    if (singleton == null) {
        synchronized (RetrofitUtils.class) {
            if (singleton == null) {
                RestAdapter.Builder builder = new RestAdapter.Builder();
                builder
                        .setEndpoint(host)
                        .setClient(new OkClient(OkHttpUtils.getInstance(context)))
                        .setRequestInterceptor(RequestIntercepts.newInstance())
                        .setConverter(new GsonConverter(GsonUtils.newInstance()))
                        .setErrorHandler(new ErrorHandlers())
                        .setLogLevel(debug ? RestAdapter.LogLevel.FULL : RestAdapter.LogLevel.NONE)/*LogLevel.BASIC will cause response.getBody().in() close*/
                        .setLog(new RestAdapter.Log() {
                            @Override
                            public void log(String message) {
                                if (message.startsWith("{") || message.startsWith("["))
                                    Logger.json(message);
                                else {
                                    Logger.i(message);
                                }
                            }
                        });
                singleton = builder.build();
            }
        }
    }
    return singleton.create(clazz);
}

下面的代码对我来说没有任何问题

Gradle

// Retrofit
implementation 'com.squareup.retrofit2:retrofit:2.5.0'
implementation 'com.squareup.retrofit2:converter-gson:2.5.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.12.1'

RetrofitClient

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(logging)
        .build();

retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .client(client)
        .build();

你也可以通过进入Android Studio底部的Profiler标签来验证结果，然后点击+号开始一个新的会话，然后在“网络”中选择所需的峰值。在那里你可以得到所有的东西，但是又麻烦又慢。请看下图。

在改装2中，你应该使用HttpLoggingInterceptor。

向build.gradle添加依赖项。截至2019年10月的最新版本为:

implementation 'com.squareup.okhttp3:logging-interceptor:4.2.1'

创建一个Retrofit对象，如下所示:

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://backend.example.com")
        .client(client)
        .addConverterFactory(GsonConverterFactory.create())
        .build();

return retrofit.create(ApiClient.class);

如果出现弃用警告，只需将setLevel更改为:

interceptor.level(HttpLoggingInterceptor.Level.BODY);

上面的解决方案为您提供的logcat消息非常类似于

setLogLevel(RestAdapter.LogLevel.FULL)

对于java.lang.ClassNotFoundException:

旧的Retrofit版本可能需要旧的日志拦截器版本。详情请看评论部分。

这里的大部分答案几乎涵盖了除了这个工具之外的所有内容，它是查看日志的最酷的方法之一。

它就是Facebook的Stetho。这是一个极好的工具来监控/记录你的应用程序的网络流量在谷歌chrome。你也可以在Github上找到。
