我做客戶端應用程序,我使用HttpClient。它完美地發送和獲取帶有拉丁符號的json,但是當我嘗試使用俄語字母(具有相同的請求地址和服務器)發送json時,它不會向服務器發送任何請求。 下面是代碼:HttpClient不發送請求與俄語字符的JSON
class RestApiClientBase {
static String _server;
static String _ssid;
final HttpClient _client = new HttpClient();
static const _codec = const JsonEncoder.withIndent(" ");
RestApiClientBase() {
_client.badCertificateCallback =
(X509Certificate cert, String host, int port) => true; //for self-signed cert
}
void setServer(String serverNew) {
_server = serverNew;
}
void setSsid(String ssidNew) {
_ssid = ssidNew;
}
dynamic invokePost(String method, String data) async {
return await _client.postUrl(Uri.parse(_server + method))
.then((HttpClientRequest request) async {
//print('11111111111111111111111');
request.headers.contentType
= new ContentType("application", "json", charset: "utf-8");
//print('22222222222222222222222');
request.contentLength = data.length;
//print('33333333333333333333333');
request.write(data);
//print('44444444444444444444444');
return await request.close();
})
.then((HttpClientResponse response) async {
if (response.statusCode == 200) {
return response
.transform(UTF8.decoder)
.single;
} else {
String errorJson = RestApiClientBase._codec.convert(
{
"status": "error",
"message": "Error code: ${response.statusCode}"
});
return errorJson;
}
}).then((String answer) async {
var json = JSON.decode(answer);
rState.setRState(method, json["status"], json["message"]);
return json;
});
}
}
class SecurityGroupClient extends RestApiClientBase {
dynamic getSGroups() async {
String json = RestApiClientBase._codec.convert(
{"ssid": RestApiClientBase._ssid});
return await invokePost("sgroup/list", json);
}
dynamic createSGroup(String name, String info) async {
String json = RestApiClientBase._codec.convert(
{"ssid": RestApiClientBase._ssid, "name": name, "info": info});
print(json);
return await invokePost("sgroup/create", json);
}
}
我得到的所有消息(111222333444),但我沒有得到任何東西。 這裏是JSON的例子:
{
「SSID」: 「6a3b1d12-cd4d-4962-ae06-34d36e31ac7e」,
「名」: 「Тестоваягруппанарусском」,
「信息「:」тест「
} 服務器使用https。
