java - 读取下载的文本文件 - FileNotFoundException

Question

请帮忙，我正在尝试从此谷歌翻译 API URL 获取数据 仅当值为 1 个单词时它才有效。如果值为 2，则会出现错误。

我的意思是这个值会起作用:

String sourceLang = "auto";
String targetLang = "en";
String sourceText = "olas";
String urlstring = "https://translate.googleapis.com/translate_a/single?client=gtx&sl=" + sourceLang + "&tl=" + targetLang + "&dt=t&q=" + sourceText;

但如果我用两个词来表达:

String sourceText = "olas olas";

它会给我 filenotfoundException 错误

这是代码:

        URL url = new URL(urlstring);
        HttpURLConnection httpURLconnection = (HttpURLConnection) url.openConnection();
        httpURLconnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.62 Safari/537.36");
        InputStream inputStream = httpURLconnection.getInputStream();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
        String line = "";
        while(line != null){
            line = bufferedReader.readLine();
            data = data + line;
        }

Answer 1

将空格替换为“%20”，例如

urlstring=urlstring.replace(" ", "%20");

URL url = new URL(urlstring);
        HttpURLConnection httpURLconnection = (HttpURLConnection) url.openConnection();
        httpURLconnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.62 Safari/537.36");
        InputStream inputStream = httpURLconnection.getInputStream();
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
        String line = "";
        while(line != null){
            line = bufferedReader.readLine();
            data = data + line;
        }
