问题描述
所以我想用一堆其他变量(字符串)将文件(图像)上传到服务器
so i want to upload a File (image) to a server with a bunch of other variable (Strings)
字符串 firstname , lastname ,birthDay, phone , adresse ;文件图片;
String firstname , lastname , birthDay, phone , adresse ; File image;
return http.post(
uri,
headers: {
'Accept': 'application/json',
"Authorization": "Bearer $token",
},
body: body,
encoding: encoding,
);
Future<http.Response> postRegisteration() async {
return await api.httpPost('fotApp/master', body: {
'firstname': 'lorem',
'lastname': 'lorem',
'birthDay': 'lorem',
'adresse': 'lorem',
'phone': 'lorem',
'image': 'lorem'
}).then((reponse) {
var data = jsonDecode(reponse.body);
print(data);
});
}
推荐答案
试试这样的
在fileList中,你应该添加任何你想上传的文件
In fileList, you should add any file you like to upload
List<MultipartFile> fileList = List();
fileList.add(MultipartFile.fromBytes(
'documents', await filePath.readAsBytes(),
filename: fileName));
其他部分参数使用params map
For other part parameters use params map
Map<String, String> params = {
"first_name": widget.mUserDetailsInputmodel.firstName,
"last_name": widget.mUserDetailsInputmodel.lastName,
"email": widget.mUserDetailsInputmodel.emailAddress,
};
然后像这样发送请求
Future<String> multipartRequest({var url, var partParams, var files}) async {
Map<String, String> headers = {
"X-API-KEY": X_API_KEY,
"Accept": "application/json",
"User-Auth-Token": authToken };
var request = http.MultipartRequest("POST", Uri.parse(url));
request.headers.addAll(headers);
if (partParams != null) request.fields.addAll(partParams);// add part params if not null
if (files != null) request.files.addAll(files);// add files if not null
var response = await request.send();
var responseData = await response.stream.toBytes();
var responseString = String.fromCharCodes(responseData);
print("responseBody " + responseString);
if (response.statusCode == 200) return responseString;
}
