在Flutter中上传带有http.post和注册表格的图片？

2024-05-21 • 问答

所以我想将文件（图像）与一堆其他变量（字符串）上传到服务器

字符串firstname，lastname，birthDay，phone，adresse；文件图像；

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);
    });
}

尝试这样的事情

在fileList中，您应该添加任何要上传的文件

    List<MultipartFile> fileList = List();
    fileList.add(MultipartFile.fromBytes(
        'documents',await filePath.readAsBytes(),filename: fileName));

对于其他零件参数，请使用参数映射

    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;
  }
