How to get client's IP address from angulardart? I failed to find this out by google.
As alternative/temporary solution, you can use ipify api to retrieve the ip:
var client = new BrowserClient();
var response = await client.get('https://api.ipify.org?format=json');
print('Response status: ${response.statusCode}');
print('Response body: ${response.body}');

I am trying to send a form data to a server and it is returning this error back : Error Message: DioError [DioErrorType.response]: Http status error [422]
How do I solve this issue?
Map<String, String> sentData = {
'firstname': data['first_name'].trim(),
'lastname': data['last_name'].trim(),
'email': data['email'].trim(),
'phone': data['phone'].trim(),
'password': data['password'],
'password_confirmation': data['password_confirmation'],
'country_id': id.toString(),
};
debugPrint('AuthControllerData : Data to Send to Server = $sentData');
final formData = dio.FormData.fromMap(sentData);
var response = await client.HttpClient(resource: 'auth/register').post(data: formData);
debugPrint('AuthController response: $response');
Is this the right way to send the FormData and are there better way like the options I have to set while using the Dio package to send formdata?
I used strapi to write queries. I checked it on postman, using "localhost" instead of IP, everything is fine. However, when I sent a request from flutter, I got an error, which I managed to avoid by using my ip instead of "localhost". But also through postman now error 502, the same error if sent via flutter
ElevatedButton(onPressed: () async {
var url = 'http://мой.айпи.43/api/pelargoniums';
Map<String,String> headers = {
'Content-Type':'application/json',
'Accept': 'application/json'
};
final response = await http.get(
Uri.parse(url),
headers: headers
);
if (response.statusCode == 200) {
print(response.body);
print('yep');
} else {
print(response.statusCode);
}
}, child: Text('wewewewew'))
Please tell me what is my problem and how to fix it?
When testing on a mobile device (Android , iOS) , you must connect within the same Wi-Fi network to use IP communication. If it is used as a web, Windows, or mac program, it can be used.
When I register a service account for the Vision API Product Search there's a json file downloaded into my desktop that has the private key. However, when making a request into this api there's no place to send that JSON. I'll show you the documentation and my code.
I didn't understand also what is the curl request and how to send it using the http post request.
And This is my code:
Future<void> uploadProductSet() async {
var projectId = 'estoOne';
var locationId = 'europe-west1';
var url = 'https://vision.googleapis.com/v1/projects/$projectId/locations/$locationId/productSets';
final responseOne = await http
.post(Uri.parse(url),
body: json.encode({
'displayName': 'Product-Set-One',
}))
.catchError((error) {
throw error;
});
print(resoinseOne.body);
}
You have to send your access token with the Authorization header.
The API seems to use the Bearer authentication method.
So set the following header in your http request: Bearer $authToken
You should get the auth-token from the credentials file you've downloaded
So your code should look something like this: (untested)
await http.post(Uri.parse(url),
headers: { 'Authorization': 'Bearer $authToken' },
body: json.encode({
'displayName': 'Product-Set-One',
})).catchError((error) {
throw error
})
I'm trying to upload a video file to GCS using a pre-signed url. I've managed to create the url via Google but now I am facing a problem using it.
Upload works in Postman, got response 200.
postman body, postman params
Code copied from Postman results in 403 Forbidden (SignatureDoesNotMatch):
Future<http.StreamedResponse> uploadVideo(
{required String uploadURL, required String filePath}) async {
var headers = {'Content-Type': 'application/octet-stream'};
var request = http.MultipartRequest('PUT', Uri.parse(uploadURL));
request.files.add(await http.MultipartFile.fromPath('file', filePath));
request.headers.addAll(headers);
http.StreamedResponse response = await request.send();
if (response.statusCode == 200) {
print(await response.stream.bytesToString());
} else {
print(response.reasonPhrase);
}
return response;
}
This is the error I am getting from Google:
<?xml version='1.0' encoding='UTF-8'?><Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your Google secret key and signing method.</Message><StringToSign>GOOG4-RSA-SHA256

Note: I needed Content-Type to be application/octet-stream so I disabled that header in Postman's automatic headers and added Content-Type manually. When I didn't do that I also got 403.
The solution was to send the file in binary.
Here is the working code:
Future<http.Response> uploadVideo(
{required String uploadURL, required String filePath}) async {
var response = await http.put(
Uri.parse(uploadURL),
headers: {'content-type': 'application/octet-stream'},
body: File(filePath).readAsBytesSync(),
);
In your Postman headers, a Token is given to GCS (first line). Given that you need authorization, Postman probably has this Token saved somewhere application-wise.
In this flutter code, the headers you're giving do not include an Auth token and therefore you're receiving a 403 error.
I am using http client for flutter network call.
My request working on postman getting response properly,
But while trying with http.post it returns error code 307-Temporary Redirect,
Method Body:
static Future<http.Response> httpPost(
Map postParam, String serviceURL) async {
Map tempParam = {"id": "username", "pwd": "password"};
var param = json.encode(tempParam);
serviceURL = "http:xxxx/Login/Login";
// temp check
Map<String, String> headers = {
'Content-Type': 'application/json',
'cache-control': 'no-cache',
};
await http.post(serviceURL, headers: headers, body: param).then((response) {
return response;
});
}
Also, the same code returns a proper response to other requests and URLs.
First I trying with chopper client but had same issue.
I am unable to detect that issue from my end of from server-side.
Any help/hint will be helpful
Try to put a slash / at the end of the serviceUrl. So, serviceUrl is serviceURL = "http:xxxx/Login/Login/" instead of serviceURL = "http:xxxx/Login/Login".
This works for me.
You need to find a way to follow redirect.
Maybe postman is doing that.
Read this >>
https://api.flutter.dev/flutter/dart-io/HttpClientRequest/followRedirects.html
Can you try with using get instead of post? At least to try and see what happend
In the documentation said:
Automatic redirect will only happen for "GET" and "HEAD" requests
only for the status codes
HttpStatus.movedPermanently (301),
HttpStatus.found (302),
HttpStatus.movedTemporarily (302, alias for HttpStatus.found),
HttpStatus.seeOther (303),
HttpStatus.temporaryRedirect (307)
keeping https instead of http in the URL it is helping me.
#Abel's answer above is correct but I had to switch from using:
Uri url = Uri.https(defaultUri, path);
to
Uri url = Uri.parse('https://todo-fastapi-flutter.herokuapp.com/plan/');
to get that last / after plan.
The first way kept dropping it so I was getting 307 errors.
flutter.dev shows a full example:
Future<http.Response> createAlbum(String title) {
return http.post(
Uri.parse('https://jsonplaceholder.typicode.com/albums'),
headers: <String, String>{
'Content-Type': 'application/json; charset=UTF-8',
},
body: jsonEncode(<String, String>{
'title': title,
}),
);
}

For Dio Http Client, use Dio Option follow redirect as True
getDioOption(){
return BaseOptions(connectTimeout: 30, receiveTimeout: 30,
followRedirects: true);
}
