#鸿蒙通关秘籍#如何在HarmonyOS中使用@ohos.net.http模块发送POST请求？

在HarmonyOS中使用@ohos.net.http模块发送HTTP POST请求时，需要构建请求体并指定请求方法为POST，以下是完整步骤：

1. 确保在config.json中添加网络访问权限：

   {
     "name": "com.example.myapplication",
     "applicableDevice": [
       {
         "deviceType": "phone",
         "appPermissions": [
           "ohos.permission.INTERNET"
         ]
       }
     ]
   }
   

2. 导入HTTP模块：

   import HttpClient from '@ohos.net.http';
   

3. 创建HTTP客户端并发送POST请求：

   async function sendPostRequest() {
     try {
       const client = new HttpClient();
       const request = new HttpClient.Request();
   
       request.setUrl('https://api.example.com/data');
       request.setMethod(HttpClient.RequestMethod.POST);
   
       request.setHeader('Content-Type', 'application/json');
   
       const requestBody = JSON.stringify({ key: 'value' });
       request.setContent(requestBody);
   
       const response = await client.sendRequest(request);
   
       if (response.getStatusCode() === 200) {
         const responseBody = await response.getContent();
         console.log('Response:', responseBody);
       } else {
         console.error('Error:', response.getStatusCode());
       }
   
     } catch (error) {
       console.error('An error occurred:', error);
     }
   }
   
   sendPostRequest();
   

在运行代码的时候，确保应用能正常联网，并确保API支持正确的认证信息。
