I have fake Api
https://fakemyapi.com/api/fake?id=220e0e14-8c78-45e9-9ef0-6ca516fde5be
and I want to print some data, I used this code
var headers = {
'Cookie': '__cfduid=d99061ead63f349023a08a33868eb7ef81619925287'
};
var request = http.Request('GET', Uri.parse('https://fakemyapi.com/api/fake?id=220e0e14-8c78-45e9-9ef0-6ca516fde5be'));
request.headers.addAll(headers);
http.StreamedResponse response = await request.send();
if (response.statusCode == 200) {
print(await response.stream.bytesToString());
}
else {
print(response.reasonPhrase);
}
and I get this response.
I/flutter (17790): {"first_ame":"Miguel","last_name":"Fay","photo":"https://s3.amazonaws.com/uifaces/faces/twitter/dhooyenga/128.jpg","email":"Keven.Cole#gmail.com","title":"Regional Functionality Developer","job_type":"Supervisor","telephone":["567.700.9452","1-701-720-0774 x9918","1-716-687-6317 x670"],"address":{"zip_code":"20909","street":"Myrtis Pines","city":"West Mekhifort","country":"Greece"},"friends":[{"first_name":"Carlie","last_name":"Kilback","email":"Erich_Emmerich90#gmail.com"},{"first_name":"Clarabelle","last_name":"Runolfsson","email":"Elise_Schroeder#gmail.com"}]}
so how to print the first name and zip code?
finally I got this solve by trying again and again,
var headers = {
'Cookie': '__cfduid=d99061ead63f349023a08a33868eb7ef81619925287'
};
var request = http.Request(
'GET',
Uri.parse(
'https://fakemyapi.com/api/fake?id=220e0e14-8c78-45e9-9ef0-6ca516fde5be'));
request.headers.addAll(headers);
http.StreamedResponse response = await request.send();
if (response.statusCode == 200) {
var item =
JsonDecoder().convert("${await response.stream.bytesToString()}");
print("item $item");
print("first_ame ${item['first_ame']}");
return item;
} else {
print(response.reasonPhrase);
}

the postman give me a code it's first time to see the same, and it dont work with me here is the postman code
var headers = {
'Accept': 'application/json'
};
var request = http.MultipartRequest('POST', Uri.parse('https://***.com/api'));
request.fields.addAll({
'action[]': 'Auth',
'action[]': 'Login',
'mobile': '1234',
'password': '1234'
});
request.headers.addAll(headers);
http.StreamedResponse response = await request.send();
if (response.statusCode == 200) {
print(await response.stream.bytesToString());
}
else {
print(response.reasonPhrase);
}
its return "Internal Server Error", I tried to edit the code
if (response.statusCode == 200) {
var item =
JsonDecoder().convert("${await response.stream.bytesToString()}");
print("item $item");
return response.statusCode;
} else {
print("response.statusCode ${response.statusCode}");
print("response.reasonPhrase :=> ${response.reasonPhrase}");
return response.statusCode;
}
and it print
I/flutter (28103): response.statusCode 500
I/flutter (28103): response.reasonPhrase :=> Internal Server Error
I contact the server programers and they told me the server work well and the website reseave the data well, please help
this is my code to get data from api in flutter but I received statuscode: 400!!!
please help.
void getProductList(String action, List<Product> list) async {
if (list.length == 0) {
var url = "http://10.0.2.2:8000/api/product";
final http.Response response= await http.get(url);
print(response.statusCode);
if (response.statusCode == 200) {
List jsonResponse = convert.jsonDecode(response.body);
for (int i = 0; i < jsonResponse.length; i++) {
setState(() {
list.add(new Product(title: jsonResponse[i]['title'],
img_url: jsonResponse[i]['img_url'],
price: int.parse(jsonResponse[i]['price'])));
});
}
}
}
}
Update
try requesting another endpoint to see if the problem is in your local server, try this:
var url = "https://jsonplaceholder.typicode.com/todos/1";
final response= await http.get(url);
print(response.statusCode);
if it worked then the problem is server-side.
Old Answer
If it's giving you StatusCode 400 then it means that the server is working fine, so probably the problem is in the request itself, try adding headers to your request.
await http.get(url, headers: {
'Content-Type': 'application/json',
'Accept': 'application/json'
},
);
if this was not the issue, can you please add the error message!
I want to upload image by multipart File request. With using this code When I pass two image files then it's working fine. But when I want to pass one image file and another is null then it's not working.
where is the problem? How can I solve this ?
Here is my code -
Future<Map<String, dynamic>> updateprofile(
UpdateProfileInfo updateProfileInfo,
File imageFile,
File signatureFile) async {
String url = "$baseAPIUrl/update-profile-info";
String _token = await SavedData().loadToken();
String authorization = "Bearer $_token";
final headers = {
'Content-Type': 'application/json',
'Accept': 'application/json',
"Authorization": authorization
};
var request = http.MultipartRequest("POST", Uri.parse(url));
request.headers.addAll(headers);
request.fields.addAll(updateProfileInfo.toJson());
request.files
.add(await http.MultipartFile.fromPath('image', imageFile.path));
request.files.add(
await http.MultipartFile.fromPath('signature', signatureFile.path));
print(" Update Profile Json ${updateProfileInfo.toJson()}");
print("Request Fields ${request.fields}");
http.StreamedResponse response = await request.send();
String respStr = await response.stream.bytesToString();
dynamic respJson;
try {
respJson = jsonDecode(respStr);
} on FormatException catch (e) {
print(e.toString());
}
print('API ${response.statusCode}\n $respJson');
bool isSuccess = response.statusCode == 200;
var data = json.decode(respStr);
return {
'isSuccess': isSuccess,
"message": isSuccess ? data["success"]["message"] : null,
"name": isSuccess ? data["success"]["name"] : null,
"classgroup": isSuccess ? data["success"]["classgroup"] : null,
"image": isSuccess ? data["success"]["image"] : null,
"error": isSuccess ? null : data['error']['message'],
};
}
Here is postman Screenshot
1.
2. POSTMAN Generated code for Dart - http
when one of your file is null, you should avoid adding it to the request body.
if(imageFile != null){
request.files
.add(await http.MultipartFile.fromPath('image', imageFile.path));
}
if(signatureFile != null){
request.files.add(
await http.MultipartFile.fromPath('signature', signatureFile.path));
}
its because signatureFile.path is going to cause an error here
using dio package should work
Future<bool> updateImage(var pickedFile) async {
SharedPreferences sharedPreferences = await SharedPreferences.getInstance();` <br/>
var token = sharedPreferences.getString("token");
Dio dio = Dio();
final File file = File(pickedFile.path);
String fileName = file.path.split('/').last;
dio.options.headers["authorization"] = token;
FormData formData = FormData.fromMap({
"image": await MultipartFile.fromFile(file.path),
});
try {
var response = await dio.post(API.kBASE_URL, data: formData);
if (response.statusCode == 200) {
return true;
} else {
return false;
}
} catch (r) {
return false;
}
}
I'm trying to upload images and some data via API from my app and I have no error in my console and I don't know what's wrong with my function.
This is the code which I use:
upload(File imageFile) async {
var user =
Provider.of<LoginUserProvider>(context, listen: false).userData.data;
DateFormat formater = DateFormat('yyyy-MM-dd');
String formatted = formater.format(dateTime);
var stream =
// ignore: deprecated_member_use
new http.ByteStream(DelegatingStream.typed(imageFile.openRead()));
var length = await imageFile.length();
var headers =
Provider.of<LoginUserProvider>(context, listen: false).httpHeader;
var uri = Uri.parse(
"xyz");
var request = new http.MultipartRequest("POST", uri);
request.headers.addAll(headers);
//request.headers.addAll(Environment.requestHeaderMedia);
var multipartFile = new http.MultipartFile(
'attachment',
stream,
length,
filename: imageFile.path,
contentType: MediaType('application', 'x-tar'),
);
request.fields['section_id'] = VillaID.toString();
request.fields['date'] = formatted;
request.fields['description'] = descriptionController.text;
request.files.add(multipartFile);
var response = await request.send();
print(response.statusCode);
response.stream.transform(utf8.decoder).listen((value) {
print(value);
});
try {
final streamedResponse = await request.send();
final response = await http.Response.fromStream(streamedResponse);
print(json.decode(response.body));
final responseData = json.decode(response.body) as Map<String, dynamic>;
if (response.statusCode == 200 || response.statusCode == 201) {
return true;
}catch (error) {
print(error);
return false;
}
return true;
}
So can anyone help me with my issue, please!
you are sending the same request twice
1st
var response = await request.send();
Second
final streamedResponse = await request.send();
before sending the same request, create them again.
regarding your code you don't need to create a response again. use the first one in the other places.
When I try to login (email and password parameter) through APIs, data passes in row format, but I want to post data in form format.
Because of this problem, when I pass data it does not accept parameter value and shows null and gives error.
So, how can I solve this problem?
> This _loginUser() method In call on login button click.
_loginUser(context) async {
Map<String, dynamic> loginBodyResponse = {
"email": _emailController.text,
"password": _passswordController.text,
};
try {
setState(() {
_isLoading = true;
});
> APIs call
Map loginResponse = await NetworkHttp.postHttpMethod(
'${AppConstants.apiEndPoint}${AppConstants.loginApi}',
loginBodyResponse);
print('email:' + _emailController.text);
print('Password:' + _passswordController.text);
print(loginBodyResponse);
print('===================Login Response=========================');
print(loginResponse['body']);
print(loginResponse['body']['login']);
print("---------------------------");
if (loginResponse['body']['status'] != "success") {
setState(() {
_isLoading = false;
});
String errormessage = loginResponse['body']['msg'];
print("---------------------------");
print(errormessage);
ErrorDialog.showErrorDialog(context, errormessage, "Error");
} else {
print("Login Successfully");
print("============================================");
setState(() {
_isLoading = false;
});
NavigatorHelper.verifyOtpScreen(context);
}
} catch (e) {
setState(() {
_isLoading = false;
});
ErrorDialog.showErrorDialog(context, e.toString(), "Error");
print('error while login $e');
}
}
NetworkHttp class which I used in above mention code. when I try to login it shows null parameter in console
class NetworkHttp {
static Future<Map<String, String>> _getHeaders() async {
final SharedPreferences prefs = await SharedPreferences.getInstance();
final String token = prefs.getString('token');
if (token != null) {
return {
'Content-type': 'application/json',
'Accept': 'application/json',
'AccessToken': '$token',
};
} else {
return {
'Content-type': 'application/json',
'Accept': 'aapilcation/json',
};
}
}
static Future<Map<String, dynamic>> postHttpMethod(String url, body) async {
print('url');
print(url);
print('body');
print(body);
Map headers = await _getHeaders();
print('headers');
print(headers);
http.Response response = await http.post(
url,
headers: headers,
body: json.encode(body),
);
Map<String, dynamic> responseJson = {
'body': json.decode(response.body),
'headers': response.headers
};
return responseJson;
}
Just add headers with the json_data .
Future<login> requestLogin(String username, String password , String device_id) async {
Map<String, String> headers = {"Content-type": "application/x-www-form-urlencoded"};
var json_body = { 'email' : username , 'password': password ,'device_id': device_id};
if(token != null){
headers.addAll({"Authorization" : "Bearer "+token});
}
// make POST request
final response = await http.post(baseUrl+ "/login", headers: headers, body: json_body);
print(response.body);
if (response.statusCode == 200) {
// If server returns an OK response, parse the JSON.
// return Post.fromJson(json.decode(response.body));
print(response.body);
return login.fromJson(json.decode(response.body));
} else {
// If that response was not OK, throw an error.
throw Exception(response.body);
}
}
With your post request just pass your parameters like this
your post request should look something like below.
response = await http.post("your_api_url",
body:{"email" : "value",
"password" : "value"});
