小编Blo*_*mer的帖子

我想获得一个dot net core 2.0 web api的令牌.

这就是我在做的事情:

C:\Users\danyb>curl -X POST -H 'Content-Type:application/json'^
Mehr? -d '{\"username\":\"mario\",\"password\":\"secret\"}'^
Mehr? localhost:56183/api/token

[1/2]: '"username":"mario"'localhost:56183/api/token --> <stdout>
--_curl_--'"username":"mario"'localhost:56183/api/token
curl: (3) Port number ended with '"'

[2/2]: '"password":"secret"'localhost:56183/api/token --> <stdout>
--_curl_--'"password":"secret"'localhost:56183/api/token
curl: (3) Port number ended with '"'

我已经在网上搜索过但找不到合适的解决方案.

TokenController类:

using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.IdentityModel.Tokens;
using System;
using System.IdentityModel.Tokens.Jwt;
using System.Security.Claims;
using System.Text;

namespace JWT.Controllers
{
    [Route("api/[controller]")]
    public class TokenController : Controller
    {
        private IConfiguration _config;

        public TokenController(IConfiguration config)
        {
            _config = config;
        } …

我想通过 Zapier 进行 api 调用以在 Slack 中打开 Modal。

但我总是收到错误：

ok: false\nerror:  invalid_json\nwarning:    missing_charset\nresponse_metadata:\nwarnings:\n1:  missing_charset\n

这是我的请求正文：

{\n"token":"XXXXXXXXX",\n"trigger_id":"XXXXXXXXXX",\n"dialog": {\n  "callback_id": "projekt-verantwortliche",\n  "title": "Projektverantwortliche ausw\xc3\xa4hlen",\n  "submit_label": "Request",\n  "state": "Limo",\n  "elements": [\n    {\n      "type": "users_select",\n      "action_id": "projekt-projektleiter",\n      "placeholder": {\n         "type":"plain_text",\n         "text":"Projektleiter ausw\xc3\xa4hlen"\n        },\n    },\n     {\n      "type": "users_select",\n      "action_id":"projekt-berater",\n      "placeholder": {\n         "type":"plain_text",\n         "text":"Berater ausw\xc3\xa4hlen"\n        }\n    }\n  ]\n}\n}\n

我究竟做错了什么？

我有一个带有REST API的回送应用程序。

我想制作一个REST API Enpoint / Email / sendEmail来发送电子邮件。我完成了本教程：https : //loopback.io/doc/en/lb3/Email-connector.html，但是它对我不起作用。

当我打开https：// localhost：3000 / explorer时，我可以看到API端点，并且可以按下按钮“尝试一下”。但是然后它会永久加载，过一会儿我在控制台中收到超时错误。

我正在做这个教程：https://hyperledger.github.io/composer/latest/installing/development-tools

现在我想启动超级账本结构，./startFabric.sh但随后出现此错误：

我有个问题。我正在使用 Angular 2。我在 html 中有一个下拉选择，在 TS 文件中有一个变量“selectedVariable”。我想在选择选项时更改 TS 文件中的变量。

例如：当某人选择：“SCRYPT”时，变量“selectedAlgorithm”将更新为值“SCRYPT”。

我是一个角度初学者，谢谢您的帮助。

HTML：

<select class="form-control" id="allocation-algorithm">
      <option value="SHA-256">SHA-256</option>
      <option value="SCRYPT">SCRYPT</option>
      <option value="ETHASH">ETHASH</option>
      <option value="CRYPTONIGH">CRYPTONIGHT</option>
      <option value="X11">X11</option>
    </select>

TS：

import {Component} from '@angular/core';

import {HashrateAllocationService} from './hashrateAllocation.service';

@Component({
  selector: 'hashrate-allocation',
  templateUrl: './hashrateAllocation.html',
  styleUrls: ['./hashrateAllocation.scss']
})
export class HashrateAllocation {
  selectedAlgorithm = "SHA-256";

  allocationTableData:Array<any>;

  constructor(private _hashrateTableService: HashrateAllocationService) {
    this.allocationTableData = _hashrateTableService.allocationTableData;
  };
}

我有一个角度应用程序：https : //github.com/XBITSwitzerland/ngx-admin/tree/ng2-admin

现在我尝试做： npm install

但是我遇到了这个错误（命令的竞赛输出太长了，因此我在这里仅分享最后一部分）：

我在 youtube 上做了以下教程：https : //www.youtube.com/watch?v=s_ht4AKnWZg

这是我的代码：

from flask import Flask, request
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app)

class HelloWorld(Resource):
    def get(self):
        return {'about':'Hello World!'}

    def post(self):
        some_json = request.get_json()
        return {'you sent': some_json}, 201

class Multi(Resource):
    def get(self, num):
        return {'result': num*10}

api.add_resource(HelloWorld, '/')
api.add_resource(Multi, '/multi/<int:num>')

if __name__ == '__main__':
    app.run(debug=True)

现在，当我运行脚本时，出现以下错误：

/home/one/systemx/test_api$ python flask_restful.py

I am very new to quorum programming. I already made some Smart Contracts with solidity on ethereum and made some dapps with Truffle, React and Metamask.

Now I did this Quorum Tutorial: https://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains

Before I get to the problem I have, I tell you what I am trying to do: Right now we have a database in our school, where the teacher can save the marks of the students, and the students can log in and see the marks they …

我有一个角度应用程序，可以使用npm start控制台中的命令启动。现在我想创建一个批处理文件，在启动时执行“npm install”。这是我创建的批处理文件：

前端.bat

cd "<path>"
npm start

当我执行文件时，控制台会很快出现，但随后什么也没有发生。

我的问题是，甚至可以在批处理文件中执行 npm start 吗？如果没有，是否有另一种方法可以使用批处理文件启动 Angular 应用程序？

谢谢

我有一个回送3应用程序。当我启动应用程序时，. node我会在控制台中看到它。

hsts deprecated The "includeSubdomain" parameter is deprecated. Use "includeSubDomains" (with a capital D) instead. node_modules/loopback/lib/server-app.js:74:25

我在node_modules文件夹中搜索，但是没有回送文件夹。那么我该如何解决呢？
