Retrofit 2.x : 记录请求和响应的 Header

Question

我正在使用改造 2.x，我想记录请求和响应的 header 和 body。

  HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new OkHttpClient.Builder()
            .addInterceptor(interceptor)
            .addInterceptor(REWRITE_CACHE_CONTROL_INTERCEPTOR)
            .addNetworkInterceptor(new Interceptor() {
                @Override
                public okhttp3.Response intercept(Chain chain) throws IOException {
                    Request request = chain.request().newBuilder()
                            .addHeader("key", "value")
                            .addHeader("HEADER","HEADER Value")
                            .build();
                    return chain.proceed(request);
                }


            }).build();

这就是我的做法，我的问题是 header 请求未登录 Android 监控但其余所有内容均已登录。

Gradle版本

 compile ('com.squareup.retrofit2:retrofit:2.0.0-beta3') {
    // exclude Retrofit’s OkHttp peer-dependency module and define your own module import
    exclude module: 'okhttp'
}
compile 'com.squareup.okhttp3:okhttp:3.0.0-RC1'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta3'
compile ('com.squareup.okhttp3:logging-interceptor:3.0.1'){
    exclude module: 'okhttp'
}

由于报告错误问题，使用 RC1 和 3.0.1 Bug Link

Answer 1

不要使用addInterceptor来添加日志拦截器，而是使用addNetworkInterceptor，以包含OkHttp添加的headers。

Network interceptors 能够：

Observe the data just as it will be transmitted over the network.

Answer 2

可能对某人有帮助...

HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.HEADERS);
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

添加两者以查看完整日志并在最后添加此拦截器（不知道为什么，但就是这样）。

Answer 3

哦，如果有人感兴趣的话，我发现了错误：

 HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(interceptor)
        .addInterceptor(REWRITE_CACHE_CONTROL_INTERCEPTOR)
        .addInterceptor(new Interceptor() {
            @Override
            public okhttp3.Response intercept(Chain chain) throws IOException {
                Request request = chain.request().newBuilder()
                        .addHeader("key", "value")
                        .addHeader("HEADER","HEADER Value")
                        .build();
                return chain.proceed(request);
            }


        }).build();

你必须在请求拦截器后面加上日志拦截器（你的拦截器变量），所以正确答案是：

 HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new Interceptor() {
            @Override
            public okhttp3.Response intercept(Chain chain) throws 
 IOException {
                Request request = chain.request().newBuilder()
                        .addHeader("key", "value")
                        .addHeader("HEADER","HEADER Value")
                        .build();
                return chain.proceed(request);
            }


        })
        .addInterceptor(interceptor)
        .addInterceptor(REWRITE_CACHE_CONTROL_INTERCEPTOR)
        .build();

Answer 4

您需要设置以下内容：

   OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
   HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
   httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.HEADERS);
   clientBuilder.addNetworkInterceptor(httpLoggingInterceptor);
   clientBuilder.build()

Answer 5

以下link非常有用： https://medium.com/swlh/okhttp-interceptors-with-retrofit-2dcc322cc3f3

OkHttpClient.Builder httpBuilder = new OkHttpClient.Builder();

//Gson Builder
GsonBuilder gsonBuilder = new GsonBuilder();
Gson gson = gsonBuilder.create();
Timber.plant(new Timber.DebugTree());

// HttpLoggingInterceptor
HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor(message -> Timber.i(message));
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);


/**
 * injection of interceptors to handle encryption and decryption
 */

//Encryption Interceptor
EncryptionInterceptor encryptionInterceptor = new EncryptionInterceptor(new EncryptionImpl());
//Decryption Interceptor
DecryptionInterceptor decryptionInterceptor = new DecryptionInterceptor(new DecryptionImpl());


// OkHttpClient. Be conscious with the order
OkHttpClient okHttpClient = new OkHttpClient()
    .newBuilder()
    //httpLogging interceptor for logging network requests
    .addInterceptor(httpLoggingInterceptor)
    //Encryption interceptor for encryption of request data
    .addInterceptor(encryptionInterceptor)
    // interceptor for decryption of request data
    .addInterceptor(decryptionInterceptor)
    .build();

//Retrofit
Retrofit retrofit = new Retrofit.Builder()
    .client(okHttpClient)
    .baseUrl(BASE_URL)
    // for serialization
    .addConverterFactory(GsonConverterFactory.create(gson))
    .build();

//ApiService
apiService = retrofit.create(ApiService.class);

Answer 6

没有添加该库需要添加

implementation 'com.squareup.okhttp3:logging-interceptor:4.7.2

对所有日志使用 Body 级别的记录器拦截器。

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

并将其添加到您的 http 客户端。默认级别为 NONE。仅供参考

enum class Level {
    /** No logs. */
    NONE,

    /**
     * Logs request and response lines.
     *
     * Example:
     * ```
     * --> POST /greeting http/1.1 (3-byte body)
     *
     * <-- 200 OK (22ms, 6-byte body)
     * ```
     */
    BASIC,

    /**
     * Logs request and response lines and their respective headers.
     *
     * Example:
     * ```
     * --> POST /greeting http/1.1
     * Host: example.com
     * Content-Type: plain/text
     * Content-Length: 3
     * --> END POST
     *
     * <-- 200 OK (22ms)
     * Content-Type: plain/text
     * Content-Length: 6
     * <-- END HTTP
     * ```
     */
    HEADERS,

    /**
     * Logs request and response lines and their respective headers and bodies (if present).
     *
     * Example:
     * ```
     * --> POST /greeting http/1.1
     * Host: example.com
     * Content-Type: plain/text
     * Content-Length: 3
     *
     * Hi?
     * --> END POST
     *
     * <-- 200 OK (22ms)
     * Content-Type: plain/text
     * Content-Length: 6
     *
     * Hello!
     * <-- END HTTP
     * ```
     */
    BODY
  }
