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?
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";
}
}
}
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";
}
}`

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。
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。
如果您正在使用Retrofit2和okhttp3，那么您需要知道Interceptor是通过队列工作的。所以在你的其他interceptor之后添加loggingInterceptor:
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
if (BuildConfig.DEBUG)
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.HEADERS);
new OkHttpClient.Builder()
.connectTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.addInterceptor(new CatalogInterceptor(context))//first
.addInterceptor(new OAuthInterceptor(context))//second
.authenticator(new BearerTokenAuthenticator(context))
.addInterceptor(loggingInterceptor)//third, log at the end
.build();
在Retrofit 2中做到这一点的最好方法是添加记录器拦截器作为networkInterceptor，这将打印出网络头和您的自定义头。重要的是要记住，拦截器作为一个堆栈工作，并确保在所有的末尾添加记录器。
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.addInterceptor(new MyCustomInterceptor());
builder.connectTimeout(60, TimeUnit.SECONDS);
builder.readTimeout(60, TimeUnit.SECONDS);
builder.writeTimeout(60, TimeUnit.SECONDS);
// important line here
builder.addNetworkInterceptor(LoggerInterceptor());
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:
https://gist.github.com/mankum93/179c2d5378f27e95742c3f2434de7168
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。
我也陷入了类似的情况，setLevel()方法没有到来，当我试图用HttpLoggingInterceptor的实例调用它时，
是这样的:
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
这是我解决它的方法，为Retrofit2生成日志，
我猜你增加了依赖关系，
implementation "com.squareup.okhttp3:logging-interceptor:4.7.2"
对于最新的版本，你可以查看，这个链接:
https://github.com/square/okhttp/tree/master/okhttp-logging-interceptor)
这里他们也解释了如何添加。
我创建了一个名为AddLoggingInterceptor的类，
这是我的代码，
public class AddLoggingInterceptor {
public static OkHttpClient setLogging(){
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.addInterceptor(loggingInterceptor)
.build();
return okHttpClient;
}
}
然后，在我们实例化我们的Retrofit时，
public static Retrofit getRetrofitInstance() {
if (retrofit == null) {
retrofit = new retrofit2.Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(AddLoggingInterceptor.setLogging()) // here the method is called inside client() method, with the name of class, since it is a static method.
.build();
}
return retrofit;
}
现在你可以看到日志生成在你的Android工作室，你可能需要搜索，okHttp过滤过程。这对我很管用。如果有任何问题，你可以给我发短信。
