我试图获得在请求中发送的确切JSON。这是我的代码:

OkHttpClient client = new OkHttpClient();
client.interceptors().add(new Interceptor(){
   @Override public com.squareup.okhttp.Response intercept(Chain chain) throws IOException {
      Request request = chain.request();
      Log.e(String.format("\nrequest:\n%s\nheaders:\n%s",
                          request.body().toString(), request.headers()));
      com.squareup.okhttp.Response response = chain.proceed(request);
      return response;
   }
});
Retrofit retrofit = new Retrofit.Builder()
   .baseUrl(API_URL)
   .addConverterFactory(GsonConverterFactory.create())
   .client(client).build();

但我只在日志里看到过这个

request:
com.squareup.okhttp.RequestBody$1@3ff4074d
headers:
Content-Type: application/vnd.ll.event.list+json

我应该如何做正确的日志记录,给定的删除setLog()和setLogLevel(),我们用来使用的Retrofit 1?


当前回答

当你和我试图问《Retrofit:爱在Android上使用api》一书的作者时,我遇到了这个问题(这里是链接)。 (不!)我不会为他们做广告....但他们真的是好人:) 作者很快就回复了我,在Retrofit 1.9和Retrofit 2.0 beta上都使用了Log方法。

下面是Retrofit 2.0 beta的代码:

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();  
// set your desired log level
logging.setLevel(Level.BODY);

OkHttpClient httpClient = new OkHttpClient();  
// add your other interceptors …

// add logging as last interceptor
httpClient.interceptors().add(logging);  // <-- this is the important line!

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

这是如何在HttpLoggingInterceptor的帮助下添加日志方法。另外,如果你是我上面提到的那本书的读者,你可能会发现它说在Retrofit 2.0中没有日志方法了——我问过作者,这是不正确的,他们明年会更新这本书来讨论这个问题。

//如果你不太熟悉Retrofit中的Log方法,我想分享更多的东西。

还应该注意,您可以选择一些日志级别。我使用关卡。BODY,它会给出这样的东西:

你可以在图片中找到几乎所有的http人员:头,内容和响应,等等。

有时候你真的不需要所有的客人都来参加你的派对:我只想知道它是否成功连接,在我的activity & Fragmetn中是否成功拨打互联网电话。然后你就可以自由使用Level了。BASIC,它将返回类似这样的东西:

你能找到里面的状态码200 OK吗?就是这样:)

还有一个,Level。HEADERS,它只返回网络的头信息。当然,这是另一张图:

这就是所有的日志技巧;)

我想和你们分享我在那里学到了很多的教程。他们有一堆很棒的帖子,谈论几乎所有与改造有关的事情,他们还在继续更新帖子,与此同时,改造2.0即将到来。请看一下这些工作,我想这会节省你很多时间。

你也可以添加Facebook的Stetho,在Chrome中查看网络痕迹: http://facebook.github.io/stetho/

final OkHttpClient.Builder builder = new OkHttpClient.Builder();
if (BuildConfig.DEBUG) {
    builder.networkInterceptors().add(new StethoInterceptor());
}

然后打开“chrome://inspect”在chrome…

下面是一个拦截器,它同时记录请求和响应体(使用Timber,基于OkHttp文档中的一个例子和其他一些SO答案):

public class TimberLoggingInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();

        long t1 = System.nanoTime();
        Timber.i("Sending request %s on %s%n%s", request.url(), chain.connection(), request.headers());
        Timber.v("REQUEST BODY BEGIN\n%s\nREQUEST BODY END", bodyToString(request));

        Response response = chain.proceed(request);

        ResponseBody responseBody = response.body();
        String responseBodyString = response.body().string();

        // now we have extracted the response body but in the process
        // we have consumed the original reponse and can't read it again
        // so we need to build a new one to return from this method

        Response newResponse = response.newBuilder().body(ResponseBody.create(responseBody.contentType(), responseBodyString.getBytes())).build();

        long t2 = System.nanoTime();
        Timber.i("Received response for %s in %.1fms%n%s", response.request().url(), (t2 - t1) / 1e6d, response.headers());
        Timber.v("RESPONSE BODY BEGIN:\n%s\nRESPONSE BODY END", responseBodyString);

        return newResponse;
    }

    private 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";
        }
    }
}

下面是一个使用HttpLoggingInterceptor从日志中过滤任何请求/响应参数的简单方法:

// Request patterns to filter
private static final String[] REQUEST_PATTERNS = {
    "Content-Type",
};
// Response patterns to filter
private static final String[] RESPONSE_PATTERNS = {"Server", "server", "X-Powered-By", "Set-Cookie", "Expires", "Cache-Control", "Pragma", "Content-Length", "access-control-allow-origin"};

// Log requests and response
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
    @Override
    public void log(String message) {

        // Blacklist the elements not required
        for (String pattern: REQUEST_PATTERNS) {
            if (message.startsWith(pattern)) {
                return;
            }
        }
        // Any response patterns as well...
        for (String pattern: RESPONSE_PATTERNS) {
            if (message.startsWith(pattern)) {
                return;
            }
        }
        Log.d("RETROFIT", message);
    }
});
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

以下是完整的要点:

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。

对于Retrofit 2.0.2,代码如下:

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient.Builder httpClient=new OkHttpClient.Builder();
        httpClient.addInterceptor(logging);

        if (retrofit == null) {
            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .client(httpClient.build())
                    .build();
        }
