如何在颤振中将 CURL [发送网格] 转换为 http 帖子?

Question

CURL 代码运行良好，可以使用 sendGrid 发送电子邮件， 我想为Flutter Dart应用程序转换此代码(因为sendGrid没有任何API(

curl --request POST   --url https://api.sendgrid.com/v3/mail/send   --header 'Authorization: Bearer 
API_KEY'   --header 'Content-Type: application/json'  
--data '{"personalizations": [{"to": [{"email": "[e-mail]"}]}],
"from": {"email": "[e-mail]"},"subject": "Hello, World!",
"content": [{"type": "text/plain", "value": "Hello World App"}]}'

请提供完整的功能

我尝试过这样的事情...但它不起作用

Future<Map<String, dynamic>> postRequest() async {
var url = 'https://api.sendgrid.com/v3/mail/send';
var body = json.encode({
"personalizations": [
{
"to": [
{"email": "[e-mail]"}
]
}
],
"from": {"email": "[e-mail]"},
"subject": "Hello, World!",
"content": [
{"type": "text/plain", "value": "sent from flutter "}
]
});
var response = await http.post(
url,
headers: {
'Authorization':
'Bearer API_KEY',
'Content-Type': 'application/json',
},
body: body,
);
// todo - handle non-200 status code, etc
print(json.decode(response.body))
return json.decode(response.body);
}

你能试试这个吗？

import 'package:http/http.dart' as http;
void main() async {
var headers = {
'Authorization': 'Bearer API_KEY',
'Content-Type': 'application/json',
};
var data = '{"personalizations": [{"to": [{"email": "[e-mail]"}]}], "from": {"email": "[e-mail]"},"subject": "Hello, World!", "content": [{"type": "text/plain", "value": "Hello World App"}]}';
var response = await http.post('https://api.sendgrid.com/v3/mail/send', headers: headers, body: data);
print(response.body);
if (response.statusCode != 200) throw Exception('http.post error: statusCode= ${response.statusCode}');

}
