我使用以下代码将Protected Sub HandLine1Size_SelectedIndexChanged(sender As Object, e As EventArgs) Handles HandLine1Size.SelectedIndexChanged
Select Case HandLine1Size.SelectedValue
Case "1"
Line1Co.Value = "12"
Case "1.5625"
Line1Co.Value = "8"
Case "2.25"
Line1Co.Value = "2"
Case "3.0625"
Line1Co.Value = "0.75"
Case Else
Line1Co.Value = "20"
End Select
End Sub

但它只打印var data = {"username": username, 'password' : password};
HttpRequest.postFormData(Service.serverUrl + "/login", data).then((response) {
if (response.status == 200) {
response.responseHeaders.forEach((key, value){
print(key);
print(value);
});
}});`

我有一个用于http请求的小型帮助程序包。它包含一个httpUtils类，该类可以返回包含标头的完整响应对象。在Flutter上也可以正常工作！
Github：https://github.com/Ephenodrom/Dart-Basic-Utils
安装：
dependencies:
basic_utils: ^1.3.0
用法：
Response response = await HttpUtils.postForFullResponse(Service.serverUrl + "/login", data);
String authData = response.headers["authorization"];
此软件包中包含的所有其他http方法：
Future<Map<Response> getForFullResponse(String url,{Map<String, dynamic> queryParameters,Map<String, String> headers});
Future<Map<String, dynamic>> getForJson(String url,{Map<String, dynamic> queryParameters,Map<String, String> headers});
Future<String> getForString(String url,{Map<String, dynamic> queryParameters,Map<String, String> headers});
Future<Map<Response> postForFullResponse(String url, String body,{Map<String, String> queryParameters,Map<String, String> headers});
Future<Map<String, dynamic>> postForJson(String url, String body,{Map<String, String> queryParameters,Map<String, String> headers});
Future<String> postForString(String url, String body,{Map<String, String> queryParameters,Map<String, String> headers});
Future<Response> putForFullResponse(String url, String body,{Map<String, String> queryParameters,Map<String, String> headers});
Future<Map<String, dynamic>> putForJson(String url, String body,{Map<String, String> queryParameters,Map<String, String> headers});
Future<String> putForString(String url, String body,{Map<String, String> queryParameters,Map<String, String> headers});
Future<Response deleteForFullResponse(String url,{Map<String, String> queryParameters,Map<String, String> headers});
Future<Map<String, dynamic>> deleteForJson(String url,{Map<String, String> queryParameters,Map<String, String> headers});
Future<String> deleteForString(String url,{Map<String, String> queryParameters,Map<String, String> headers});
Map<String, dynamic> getQueryParameterFromUrl(String url);
String addQueryParameterToUrl(String url, Map<String, dynamic> queryParameters);
