javascript - 如何使用环回 4 执行发布请求

Question

经过一番研究，我发现了环回代理服务，它允许我使用 get 方法进行一些查询。但我不知道如何使用请求正文中的数据执行 POST 请求。

我的服务

import {getService} from '@loopback/service-proxy';
import {inject, Provider} from '@loopback/core';
import {StorageApiDataSource} from '../datasources';
/**
 * user for  both storageApi service and authApi service
 */
export interface StorageApiService {
  // this is where you define the Node.js methods that will be
  // mapped to the SOAP operations as stated in the datasource
  // json file.

  getrestdata(id?: number): Promise<StorageApiResponseData>;
  saveFile(token?: string,requestBody:any): Promise<StorageApiResponseData>;

}
export interface StorageApiResponseData {
  file_id: string;
  direct_url: string;
}

export class StorageApiServiceProvider implements Provider<StorageApiService> {
  constructor(
    // storageApi must match the name property in the datasource json file
    @inject('datasources.storageApi')
    protected dataSource: StorageApiDataSource = new StorageApiDataSource(),
  ) {}

  value(): Promise<StorageApiService> {
    return getService(this.dataSource);
  }
}

Answer 1

在您的数据源文件中，在操作数组中为您的 post 函数添加一个模板，其中postFunction是函数名称。并在您的服务接口中添加相同的内容。

"operations": [{
      "template": {
        "method": "POST",
        "url": "{POST-API-URL}",
        "headers": {
          "accepts": "application/json",
          "content-type": "application/json"
        },
        "json": {
          "param1": "{value1}",
          "param2": "{value2}",
          "param3": "{value3}"
        }
      },
      "functions": {
        "postFunction": [
          "value1",
          "value2",
          "value3"
        ]
      }
    }]

经过深海，我终于找到了答案。我们只需要将方法定义为 POST 并传递一些参数，这些参数将用作这些请求表单参数的变量。希望它可以帮助这里的人。

 {
  "name": "SendNotif",
    "connector": "rest",
    "baseURL": "",
    "crud": false,
   "options": {
   "headers": {
           "accept": "application/json",
           "authorization": " MY AUTH KEY",
            "content-type": "application/json"
              }
  },
"operations": [
  { "template": {
     "method": "GET",
     "url":"MY URL"

     },
     "functions": {
      "send_sms": ["PARAM1","PARAM2","PARAM3"]
    },
   "template": {
     "method": "POST",
     "url":"MY URL"

     },
     "functions": {
      "send_sms":["PARAM1","PARAM2","PARAM3"]
    }
 }
]
}
