Google 语言检测 api 回复错误代码 406
我正在尝试使用 Google 语言检测 API，现在我正在使用 Google 文档上提供的示例，如下所示：
public static String googleLangDetection(String str) throws IOException, JSONException{
String urlStr = "http://ajax.googleapis.com/ajax/services/language/detect?v=1.0&q=";
// String urlStr = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=Paris%20Hilton";
URL url = new URL(urlStr+str);
URLConnection connection = url.openConnection();
// connection.addRequestProperty("Referer","http://www.hpeprint.com");
String line;
StringBuilder builder = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
while((line = reader.readLine()) != null) {
builder.append(line);
}
JSONObject json = new JSONObject(builder.toString());
for (Iterator iterator = json.keys(); iterator.hasNext();) {
String type = (String) iterator.next();
System.out.println(type);
}
return json.getString("language");
}
但我收到 http 错误代码“406”。
我无法理解问题是什么？正如下面的谷歌搜索查询（评论）它工作正常。
当我在 Firefox 或 IE 中运行时，生成的语言检测 url 本身工作正常，但在我的 java 代码中失败。
我做错了什么吗？

I am trying to use Google language detection API, Right now I am using the sample available on Google documentation as follows:
public static String googleLangDetection(String str) throws IOException, JSONException{
String urlStr = "http://ajax.googleapis.com/ajax/services/language/detect?v=1.0&q=";
// String urlStr = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=Paris%20Hilton";
URL url = new URL(urlStr+str);
URLConnection connection = url.openConnection();
// connection.addRequestProperty("Referer","http://www.hpeprint.com");
String line;
StringBuilder builder = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
while((line = reader.readLine()) != null) {
builder.append(line);
}
JSONObject json = new JSONObject(builder.toString());
for (Iterator iterator = json.keys(); iterator.hasNext();) {
String type = (String) iterator.next();
System.out.println(type);
}
return json.getString("language");
}
But I am getting http error code '406'.
I am unable to understand what the problem is? As the google search query(commented) below it is working fine.
The resultant language detection url itself is working fine when I run it in firefox or IE but it's failing in my java code.
Is there something I am doing wrong?
Thanks in advance

据猜测，
str上传入的任何内容都包含在 URL 中无效的字符，因为错误代码406为Not Acceptable，当存在内容编码问题时看起来会返回。经过快速谷歌搜索后，您似乎需要通过 java.net.URLEncoder 类，然后将其附加到 URL。
As a guess, whatever is being passed in on
strhas characters that are invalid in a URL, as the error code406isNot Acceptable, and looks to be returned when there is a content encoding issue.After a quick google, it looks like you need to run your
strthrough the java.net.URLEncoder class, then append it to the URL.在以下链接找到答案：

必须修改代码如下：
