【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：
import java.io.IOException;
import java.io.PrintWriter;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import okhttp3.ResponseBody;
public class EmulateLoginBaidu {
OkHttpClient client = new OkHttpClient();
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 {
System.out.println("Try Emulate Login Baidu");
String baiduUrl = "http://www.baidu.com";
EmulateLoginBaidu emulateLogin = new EmulateLoginBaidu();
// ResponseBody respBody = emulateLogin.run(baiduUrl);
Response response = emulateLogin.run(baiduUrl);
System.out.println("response=" + response);
String respBodyStr = response.body().string();
}
}结果
String respBodyStr = response.body().string();
出错：
Exception in thread "main" java.lang.IllegalStateException: closed at okio.RealBufferedSource.rangeEquals(RealBufferedSource.kt:402) at okio.RealBufferedSource.rangeEquals(RealBufferedSource.kt:393) at okhttp3.internal.Util.bomAwareCharset(Util.java:469) at okhttp3.ResponseBody.string(ResponseBody.java:175) at EmulateLoginBaidu.main(EmulateLoginBaidu.java:47) Disconnected from the target VM, address: '127.0.0.1:56071', transport: 'socket' Process finished with exit code 1
okhttp response body string Exception in thread “main” java.lang.IllegalStateException: closed
okhttp response body string java.lang.IllegalStateException: closed
还是去试试：
Response response = emulateLogin.run(baiduUrl);
ResponseBody body = response.body();
String bodyString = body.string();
MediaType contentType = body.contentType();
Response savedResponse = response
.newBuilder()
.body(ResponseBody.create(contentType, bodyString))
.build();
System.out.println("savedResponse=" + savedResponse);
String respBodyStr = savedResponse.body().string();尝试去用 重新保存的response，去后续多次使用，结果是同样的错误：
又试了：
ResponseBody respBody = response.body();
System.out.println("respBody=" + respBody);
String respBodyStr = respBody.string();也会导致同样错误
ResponseBody respBody = response.body();
// System.out.println("respBody=" + respBody);
String respBodyStr = respBody.string();
System.out.println("respBodyStr=" + respBodyStr);依旧错误。
如果只是用一次，就直接用代码，保证用一次即可
如果想要多次使用，则参考
去想办法弄那个：intercept
【已解决】拦截器interceptor的作用和如何实现OkHttp的interceptor
【总结】
最后用拦截器：
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();
}
}
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(new LoggingInterceptor())
.addInterceptor(new ResponseInterceptor())
.build();
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);可以正常获取
response.body().string()
了。
