标签：拦截器 return val 自定义 -- request Request Okhttp response
Okhttp中自带的日志拦截器 HttpLoggingInterceptor 实在是不好用，日志太多太乱，所以想要有好看、简洁的日志打印就要靠自定义了，下面分享我参照 HttpLoggingInterceptor 写的自定义日志打印拦截器，分为java版本和kotlin版本：
1、kotlin：
class CustomLogInterceptor : Interceptor {
override fun intercept(chain: Interceptor.Chain): Response {
val request = chain.request()
val requestLog = generateRequestLog(request)
val response = chain.proceed(request)
val responseLog = generateResponseLog(response)
LogUtils.w(requestLog.plus(responseLog))
return response
}
private fun generateResponseLog(response: Response?): String {
if (response == null) {
return ""
}
return "Response Time-->：${
TimeUtils.millis2String(System.currentTimeMillis())
} \r\n Response Result ${
if (response.code != 200)
response.code
else
""
} -->：${
getResponseText(response)
}"
}
private fun generateRequestLog(request: Request?): String {
if (request == null) {
return ""
}
val requestParams = getRequestParams(request)
val needPrintRequestParams = requestParams.contains("IsFile").not()
return "自定义日志打印 \r\n Request Time-->：${
TimeUtils.millis2String(System.currentTimeMillis())
} \r\n Request Url-->：${request.method} ${request.url} \r\n Request Header-->：${
getRequestHeaders(
request
)
} \r\n Request Parameters-->：${
if (needPrintRequestParams)
requestParams
else
"文件上传，不打印请求参数"
} \r\n "
}
@Deprecated("unused")
private fun printInfo(request: Request?, response: Response?) {
if (request != null && response != null) {
val requestParams = getRequestParams(request)
val needPrintRequestParams = requestParams.contains("IsFile").not()
val logInfo =
"自定义日志打印 \r\n Request Url-->：${request.method} ${request.url} \r\n Request Header-->：${
getRequestHeaders(
request
)
} \r\n Request Parameters-->：${
if (needPrintRequestParams)
requestParams
else
"文件上传，不打印请求参数"
} \r\n Response Result ${
if (response.code != 200)
response.code
else
""
} -->：${
getResponseText(response)
}"
LogUtils.w(logInfo)
}
}
/**
* 获取请求参数
*/
private fun getRequestParams(request: Request): String {
var str: String? = null
try {
request.body?.let {
val buffer = Buffer()
it.writeTo(buffer)
val charset = it.contentType()?.charset(Charset.forName("UTF-8"))
?: Charset.forName("UTF-8")
str = buffer.readString(charset)
}
} catch (e: Exception) {
e.printStackTrace()
}
return if (str.isNullOrEmpty()) "Empty!" else str!!
}
private fun getRequestHeaders(request: Request): String {
val headers = request.headers
return if (headers.size > 0) {
headers.toString()
} else {
"Empty!"
}
}
/**
* 获取返回数据字符串
*/
private fun getResponseText(response: Response): String {
try {
response.body?.let {
val source = it.source()
source.request(Long.MAX_VALUE)
val buffer = source.buffer
val charset = it.contentType()?.charset(Charset.forName("UTF-8"))
?: Charset.forName("UTF-8")
if (it.contentLength().toInt() != 0) {
buffer.clone().readString(charset).let { result ->
return result
}
}
}
} catch (e: Exception) {
e.printStackTrace()
}
return "Empty!"
}
}
2、Java：
public class CustomLogInterceptor implements Interceptor {
@Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
Response response = chain.proceed(request);
printInfo(request, response);
return response;
}
private void printInfo(Request request, Response response) {
if (request != null && response != null) {
String logInfo = "自定义日志打印".concat(" \r\n ")
.concat("Request Url-->：")
.concat(request.method())
.concat(" ")
.concat(request.url().toString())
.concat(" \r\n ")
.concat("Request Header-->：")
.concat(getRequestHeaders(request))
.concat(" \r\n ")
.concat("Request Parameters-->：")
.concat(getRequestParams(request))
.concat(" \r\n ")
.concat("Response Result-->：")
.concat(getResponseText(response));
Logger.w(logInfo);
}
}
private String getResponseText(Response response) {
String str = "Empty!";
try {
ResponseBody body = response.body();
if (body != null && body.contentLength() != 0) {
BufferedSource source = body.source();
source.request(Long.MAX_VALUE);
Buffer buffer = source.buffer();
MediaType mediaType = body.contentType();
if (mediaType != null) {
@SuppressWarnings("CharsetObjectCanBeUsed") Charset charset = mediaType.charset(
Charset.forName("UTF-8"));
if (charset != null) {
str = buffer.clone().readString(charset);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return str;
}
private String getRequestParams(Request request) {
String str = "Empty!";
try {
RequestBody body = request.body();
if (body != null) {
Buffer buffer = new Buffer();
body.writeTo(buffer);
MediaType mediaType = body.contentType();
if (mediaType != null) {
@SuppressWarnings("CharsetObjectCanBeUsed") Charset charset = mediaType.charset(
Charset.forName("UTF-8"));
if (charset != null) {
str = buffer.readString(charset);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return str;
}
private String getRequestHeaders(Request request) {
Headers headers = request.headers();
if (headers.size() > 0) {
return headers.toString();
} else {
return "Empty!";
}
}
}
其中使用到的第三方SDK为：
日志打印：AndroidUtilCode
网络请求：OkHttp
打印效果：
Kotlin版本仅仅比Java版本多了两行时间的打印，从而可以计算当前请求的 大概 耗时，如果需要精确的耗时请使用 OkHttpClient.Builder().eventListener(eventListener: EventListener)
