Retrofit 2.x：请求和响应的日志标头

Question

我正在使用retrofit 2.x，我想记录请求和响应的标题和正文。

  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();

这就是我正在做的，我的问题是请求的标题没有记录在Android监视器，但休息一切都记录下来。

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bug报告Bug Link使用RC1和3.0.1

Answer 1

哦，如果有人有兴趣，我发现错误：

 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();

您必须在请求拦截器之后添加日志拦截器（您的拦截器变量），因此正确的答案是：

 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();

可以帮助别人......

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

添加两个以查看完整日志并在最后添加此拦截器（不知道为什么，但它像这样）。

Answer 3

不使用addInterceptor添加日志记录拦截器，而是使用addNetworkInterceptor来包含由OkHttp添加的标头。

Network interceptors能够：

观察数据，就像它将通过网络传输一样。

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()
