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";
}
}
}
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);

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。
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";
}
}`
