折腾：
【未解决】Java中如何保存字符串到文件中且指定编码
期间，用代码：
class LoggingInterceptor implements Interceptor {
@Override public Response intercept(Interceptor.Chain chain) throws IOException {
Request request = chain.request();
long t1 = System.nanoTime();
// logger.info(String.format("Sending request %s on %s%n%s",
// request.url(), chain.connection(), request.headers()));
Logger.info("Sending request url={} on connection={}, headers={}",
request.url(), chain.connection(), request.headers());
Response response = chain.proceed(request);
long t2 = System.nanoTime();
// logger.info(String.format("Received response for %s in %.1fms%n%s",
// response.request().url(), (t2 - t1) / 1e6d, response.headers()));
Logger.info("Received response for url={} in {}, headers={}",
response.request().url(), (t2 - t1) / 1e6d, response.headers());
return response;
}
}
class ResponseInterceptor implements Interceptor {
@Override public Response intercept(Chain chain) throws IOException {
Response response = chain.proceed(chain.request());
ResponseBody body = response.body();
String bodyString = body.string();
MediaType contentType = body.contentType();
Logger.debug("Response={}", bodyString);
return response.newBuilder().body(ResponseBody.create(contentType, bodyString)).build();
}
}
public class EmulateLoginBaidu {
// OkHttpClient client = new OkHttpClient();
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new LoggingInterceptor())
.addInterceptor(new ResponseInterceptor())
.build();
String UserAgent_Mac_Chrome = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36";
// ResponseBody run(String url) throws IOException {
Response run(String url) throws IOException {
Request request = new Request.Builder()
.url(url)
.header("User-Agent", UserAgent_Mac_Chrome)
.header("Host", "www.baidu.com")
.header("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8")
.header("Accept-Encoding", "gzip, deflate, br")
.header("Accept-Language", "zh-CN,zh;q=0.9,en;q=0.8")
.header("Cache-Control", "no-cache")
.build();
try (Response response = client.newCall(request).execute()) {
// return response.body().string();
// return response.body();
return response;
}
}
public static void main(String[] args) throws IOException {
String logFilename = "log/EmulateLoginBaidu.log";
CrifanUtil.initLogger(logFilename);
Logger.info("logFilename={}", logFilename);
Logger.info("Try Emulate Login Baidu");
String baiduUrl = "http://www.baidu.com";
// Logger.info("baiduUrl=%s", baiduUrl);
Logger.info("baiduUrl={}", baiduUrl);
EmulateLoginBaidu emulateLogin = new EmulateLoginBaidu();
// ResponseBody respBody = emulateLogin.run(baiduUrl);
Response response = emulateLogin.run(baiduUrl);
ResponseBody respBody = response.body();
String respBodyStr = respBody.string();
// String respBodyStr = response.body().string();
Logger.info("respBodyStr={}", respBodyStr);
try (PrintWriter printWriter = new PrintWriter("debug/baidu_com.html")) {
printWriter.println(respBodyStr);
}
}
}发现OkHttp虽然可以返回字符串了，但是全是乱码：
不论是console（UTF-8编码）中：
还是UTF-8的log文件中：
而本身网站的编码，去Chrome中调试确定是utf-8的：
okhttp body string messy code
我刚用猜到，估计是用了压缩导致的，去掉：
.header("Accept-Encoding", "gzip, deflate, br")结果：
就不是乱码了：
【总结】
此处是在OkHttp的请求中加上了：
.header("Accept-Encoding", "gzip, deflate, br")导致返回的是gzip压缩后的数据
-》直接打印就是乱码
解决办法：
要么自己去想办法解压缩
要么直接去掉Accept-Encoding
如果不加，则OkHttp会自动加上，以及加压缩返回的字符串
