我想用简单的令牌执行基本身份验证;如何在颤动中执行此操作？哪种方式最好？
List<String> hotelCodes = redisTemplate.execute(new RedisCallback<List<String>>() {
/**
* Gets called by {@link RedisTemplate} with an active Redis connection. Does not need to care about activating or
* closing the connection or handling exceptions.
*
* @param connection active Redis connection
* @return a result object or {@code null} if none
* @throws DataAccessException
*/
@Override
public List<String> doInRedis(RedisConnection connection) throws DataAccessException {
ScanOptions options = ScanOptions.scanOptions().match(pattern).count(1).build();
Cursor<Map.Entry<byte[], byte[]>> entries = connection.hScan(HASH_KEY.getBytes(), options);
List<String> result = new ArrayList<>();
if (entries != null)
while (entries.hasNext()) {
Map.Entry<byte[], byte[]> entry = entries.next();
byte[] actualValue = entry.getValue();
result.add(new String(actualValue));
}
return result;
}
});
return hotelCodes;
是否足以添加身份验证标头，例如以这种方式？

我正在使用JWT令牌类型
答案 0 :(得分：0)
你可以使用这样的东西。
var request = new http.Request('POST', Uri.parse(url));
request.headers[HttpHeaders.CONTENT_TYPE] = 'application/json';
request.headers[HttpHeaders.AUTHORIZATION] = token;
request.body = json.encode(loginRequest.toMap());
await client.send(request).then((response) {
response.stream.bytesToString().then((value) {
print(value.toString());
jsonResponse = value.toString();
completer.complete(jsonResponse);
});
}).catchError((error) {
print(error.toString());
});
答案 1 :(得分：0)
请注意Bearer这个词必须以其他方式大写，不知道是什么原因，但是对于颤抖的http调用，请确保大写这样的词
var response = await httpClient.post(
url,
headers:{
"Accept": "application/json",
"Content-type": "application/json",
"Authorization": "Bearer $token"
},
body :{some body});
答案 2 :(得分：0)
我将更喜欢使用具有许多功能的Dio库。 文件上传也超级容易。 Dio本身处理了很多事情。
答案 3 :(得分：0)
我使用键/值对字典作为标头信息。我使用 dart 类的 fromJson 方法来序列化类型为 YourClass 的对象列表。
import 'package:http/http.dart' as http
String token = jwtToken;
var client = http.Client();
Map<String, String> headers = new HashMap();
headers['Accept'] = 'application/json';
headers['Content-Type'] = 'application/json';
headers['Authorization'] = 'Bearer $token';
var response = await client
.post(url,
headers: headers,
body: json.encode(param),
encoding: Encoding.getByName('utf-8'))
.timeout(_TIMEOUT);
if (response.statusCode == 200) {
var parsed = json.decode(response.body).cast<Map<String, dynamic>>();
list = parsed
.map<YourClass>((json) => YourClass.fromJson(json))
.toList();
}
