如何添加用于授权和内容类型flutter的标头

Question

我有这个代码用于调用api；如何向其中添加授权和内容类型标头？

final url = Uri.parse('https://api.collectapi.com/economy/hisseSenedi');
var counter;
var hisseResult;
Future callHisse() async {
try{
final response = await http.get(url);
if(response.statusCode == 200){
var result = hisselistFromJson(response.body);
if(mounted);
setState(() {
counter = result.data.length;
hisseResult = result;
});
return result;
} else {
print(response.statusCode);
}
} catch(e) {
print(e.toString());
}

}

感谢您的帮助

您可以这样做：

Map<String, String> requestHeaders = {
'Content-type': 'application/json',
'Authorization': '<Your token>'
};
final response = await http.get(url,headers:requestHeaders);
