我想使用模型并发送到服务器。

例如，发送评论。

评论.model.ts

export interface Comment {
  article_no: number;
  username: string;
  nickname: string;
  creatat: Date;
  content: string;
}

评论.service.ts

import { Injectable } from '@angular/core';
import { ApiService } from '.';
import { Observable } from 'rxjs/Observable';
import { Comment } from '..';

@Injectable()
export class CommentService {

  constructor(
    private apiService: ApiService
  ) { }

  public writeComment(comment: Comment) {
    return this.apiService.post('/api/comment/', comment);
  }
}

comment.component.html （我使用材质 UI）

<form class="comment-form">
  <mat-form-field class="example-full-width">
    <textarea matInput matTextareaAutosize [formControl]="content" placeholder="comment"></textarea>
  </mat-form-field>
  <button class="ui primary …

我想将字符串转换为Json并给它一个返回值。

c.JSON(200, string(body))通过 POST 请求（writePost）接收到的值是：

"{\"消息\":{\"@type\":\"响应\",\"@service\":\"service.community.cafe\",\"@version\":\"1.0. 0\",\"状态\":\"200\",\"结果\":{\"msg\":\"成功\",\"url\":\"aaabcd\",\"articleId \":211,\"articleUrl\":\" https://abcde.com/abc/211 \"}}}"

// WriteResult Struct
type WriteResult struct {
    Message    int    `form:"msg" json:"msg"`
    URL        string `form:"url" json:"url"`
    ArticleID  int    `form:"articleId" json:"articleId"`
    ArticleURL string `form:"articleUrl" json:"articleUrl"`
}

func writePost(c *gin.Context) {
    var writeInfo WriteInfo

    if err := c.ShouldBind(&writeInfo); err != nil {
        fmt.Println("error : ", err)
    }

    url := "https://openapi.abcde.com/articles"

    var bearer = "Bearer " + writeInfo.AccessToken
    var bufs bytes.Buffer

    form := url.Values{}
    form.Add("subject", subject)
    form.Add("content", content)

    req, err := http.NewRequest("POST", url, …
