logger 是Android 的日志管理工具
github地址 https://github.com/orhanobut/logger
一 簡(jiǎn)單使用
使用步驟：
(1):首先在Android Studio 的glide文件中添加依賴
compile 'com.orhanobut:logger:1.15'
初始化logger 可以在自定義Application 中對(duì)logger 進(jìn)行初始化 【不進(jìn)行初始化也可以正常使用】
/**
* 初始化logger 默認(rèn)tag = PRETTYLOGGER
*/
Logger.init();
/**
* 初始化logger 自定義TAG
*/
Logger.init(TAG);
之后就可以使用logger 打印日志
先看一下logger的打印API
logger 提供了非常豐富的方法用來打印相關(guān)數(shù)據(jù)下面我們逐個(gè)分析一下使用方式
創(chuàng)建幾個(gè)變量用于打印數(shù)據(jù)
int number = 10;
String id = "1323290412";
String message = "msg";
String name = "小明";
List<String> strings = new ArrayList<>(Arrays.asList("北京","上海"));
List<City> cityList = new ArrayList<>(Arrays.asList(
new City("北京"),
new City("上海"),
new City("廣州"),
new City("杭州")));
- logger.i() 和 logger.i()打印格式化字符串
效果如下：
2.logger.d() 打印數(shù)組拾枣，對(duì)象數(shù)據(jù)等
Logger.d(strings);
Logger.d(cityList);
效果如下：
自定義Java bean
private String cityName;
public City(String cityName) {
this.cityName = cityName;
}
public String getCityName() {
return cityName;
}
public void setCityName(String cityName) {
this.cityName = cityName;
}
@Override
public String toString() {
return "City{" + "cityName='" + cityName + '\'' + '}';}
logger.e() 打印錯(cuò)誤日志和logger.log()等 打印自定義Tag 日志 使用方式大同小異就不介紹了
Logger.t(TAG).d(message);
logger.t() 可用于打印臨時(shí)Tag,不同于Application 初始化中的TAG 這樣就非常方便了
3.logger.json() 打印json 數(shù)據(jù)
效果如下:
打印 Json
4.logger.xml() 打印Xml 類型數(shù)據(jù)
效果如下:
打印 Xml
二 結(jié)合OKHttp使用
以上就是logger 的基本使用方式，可以使用logger 與OkHttp 結(jié)合打印http 請(qǐng)求相關(guān)數(shù)據(jù) 先看一下效果圖:
LoggerHttpInterceptor
利用logger 實(shí)現(xiàn)與OKhttp結(jié)合打印請(qǐng)求數(shù)據(jù) 需要借助OKhttp的網(wǎng)絡(luò)攔截器 在自定義網(wǎng)絡(luò)攔截器 實(shí)現(xiàn)Interceptor 接口 中添加logger 打印信息，自定義網(wǎng)絡(luò)攔截器代碼如下:
private static final String TAG = "OKHttp";
private static final Charset UTF8 = Charset.forName("UTF-8");
public LoggerHttpInterceptor() {
}
@Override
public Response intercept(Chain chain) throws IOException {
//log 信息
StringBuilder builder = new StringBuilder();
Request request = chain.request();
RequestBody requestBody = request.body();
boolean hasRequestBody = requestBody != null;
Connection connection = chain.connection();
Protocol protocol = connection != null ? connection.protocol() : Protocol.HTTP_1_1;
String requestStartMessage = "請(qǐng)求方式----> " + request.method() + "\n請(qǐng)求地址: " + request.url() + "\nHttp 版本:" + protocol;
builder.append(requestStartMessage);
if (hasRequestBody) {
if (requestBody.contentType() != null) {
builder.append("\n請(qǐng)求頭:----> Content-Type: " + requestBody.contentType());
}
}
builder.append("\n請(qǐng)求參數(shù):");
Headers headers = request.headers();
for (int i = 0, count = headers.size(); i < count; i++) {
String name = headers.name(i);
// Skip headers from the request body as they are explicitly logged above.
if (!"Content-Type".equalsIgnoreCase(name) && !"Content-Length".equalsIgnoreCase(name)) {
builder.append(name + ": " + headers.value(i));
}
}
// builder.append("\n請(qǐng)求參數(shù):---end");
if (!hasRequestBody) {
builder.append("\n請(qǐng)求結(jié)束 --> END " + request.method());
} else if (bodyEncoded(request.headers())) {
builder.append("\n請(qǐng)求結(jié)束 --> END " + request.method() + " (encoded body omitted)");
} else {
Buffer buffer = new Buffer();
requestBody.writeTo(buffer);
Charset charset = UTF8;

if (contentType != null) {
charset = contentType.charset(UTF8);
}
if (isPlaintext(buffer)) {
builder.append("\n" + buffer.readString(charset));
builder.append("\n請(qǐng)求結(jié)束 --> END " + request.method()
+ " (" + requestBody.contentLength() + "-byte body)");
} else {
builder.append("\n請(qǐng)求結(jié)束 --> END " + request.method() + " (binary "
+ requestBody.contentLength() + "-byte body omitted)");
}
}
long startNs = System.nanoTime();
Response response;
try {
response = chain.proceed(request);

throw e;
}

BufferedSource source = responseBody.source();
source.request(Long.MAX_VALUE);
// Buffer the entire body.
Buffer buffer = source.buffer();
Charset charset = UTF8;
MediaType contentType = responseBody.contentType();
if (contentType != null) {
try {
charset = contentType.charset(UTF8);
} catch (UnsupportedCharsetException e) {
builder.append("\nCouldn't decode the response body; charset is likely malformed.");
builder.append("\n<-- END HTTP");
return response;
}
}
if (!isPlaintext(buffer)) {
builder.append("\n<-- END HTTP (binary " + buffer.size() + "-byte body omitted)");
return response;
}
if (contentLength != 0) {

builder.append("\n" + buffer.clone().readString(charset));
}
builder.append("\n<-- 請(qǐng)求結(jié)束 END HTTP (" + buffer.size() + "-byte body)");
Logger.t(TAG).d("請(qǐng)求信息如下:\n" + builder);
return response;
}
