我在使用从网页抓取的 JSON 数组时遇到了奇怪的字符编码问题。服务器正在发回此 header :
内容类型文本/javascript; charset=UTF-8
我还可以查看 Firefox 或任何浏览器中的 JSON 输出,并且 Unicode 字符正确显示。响应有时会包含来自另一种语言的带有重音符号等的单词。但是,当我将其拉下并将其放入 Java 中的字符串时,我得到了那些奇怪的问号。这是我的代码:
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "utf-8");
params.setBooleanParameter("http.protocol.expect-continue", false);
HttpClient httpclient = new DefaultHttpClient(params);
HttpGet httpget = new HttpGet("http://www.example.com/json_array.php");
HttpResponse response;
try {
response = httpclient.execute(httpget);
if(response.getStatusLine().getStatusCode() == 200){
// Connection was established. Get the content.
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no need
// to worry about connection release
if (entity != null) {
// A Simple JSON Response Read
InputStream instream = entity.getContent();
String jsonText = convertStreamToString(instream);
Toast.makeText(getApplicationContext(), "Response: "+jsonText, Toast.LENGTH_LONG).show();
}
}
} catch (MalformedURLException e) {
Toast.makeText(getApplicationContext(), "ERROR: Malformed URL - "+e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "ERROR: IO Exception - "+e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
} catch (JSONException e) {
Toast.makeText(getApplicationContext(), "ERROR: JSON - "+e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
private static String convertStreamToString(InputStream is) {
/*
* To convert the InputStream to String we use the BufferedReader.readLine()
* method. We iterate until the BufferedReader return null which means
* there's no more data to read. Each line will appended to a StringBuilder
* and returned as String.
*/
BufferedReader reader;
try {
reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
StringBuilder sb = new StringBuilder();
String line;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
如您所见,我在 InputStreamReader 上指定了 UTF-8,但每次我通过 Toast 查看返回的 JSON 文本时,都会出现奇怪的问号。我在想我需要将 InputStream 发送到 byte[] 吗?
提前感谢您的帮助。
最佳答案
试试这个:
if (entity != null) {
// A Simple JSON Response Read
// InputStream instream = entity.getContent();
// String jsonText = convertStreamToString(instream);
String jsonText = EntityUtils.toString(entity, HTTP.UTF_8);
// ... toast code here
}
