从命令行Dart获取HTTP响应最简单的方法是什么？ [英] What is the easiest way to get an HTTP response from command-line Dart?

问题描述

我在Dart写了一个命令行脚本。

解决方案

使用 http包，以便轻松地对HTTP资源进行命令行访问。虽然核心 dart：io 库具有HTTP客户端的原语（请参阅 HttpClient ），http包使GET，POST等更容易。

首先，在您的pubspec依赖项中添加http ：

  name：sample_app 
 description：我的示例应用程序。 
 dependencies：
 http：any 
  

安装软件包。在命令行或通过Dart编辑器运行：

  pub install 
  pre> 
 
 
导入程序包：
  // in your app 
 import'package：http / http.dart'as http; 
  
发出GET请求。  get（）函数返回未来。
  http.get（'http://example.com/hugs'）.then（（response）=> print（response.body））; 
  
最好的做法是使用 get ：
 未来getAndParse（String uri）{
 return http.get（'http://example.com/hugs'）
 .then（（response）=> JSON.parse（response.body））; 
} 
  
不幸的是，我找不到任何正式的文档。所以我不得不看看代码（它有很好的意见）： https://code.google.com/p/dart/source/browse/trunk/dart/pkg/http/lib/http.dart  
 
I am writing a command-line script in Dart. What's the easiest way to access (and GET) an HTTP resource?
解决方案
Use the http package for easy command-line access to HTTP resources. While the core dart:io library has the primitives for HTTP clients (see HttpClient), the http package makes it much easier to GET, POST, etc.

First, add http to your pubspec's dependencies:
name: sample_app
description: My sample app.
dependencies:
  http: any
Install the package. Run this on the command line or via Dart Editor:
pub install
Import the package:
// inside your app
import 'package:http/http.dart' as http;
Make a GET request. The get() function returns a Future.
http.get('http://example.com/hugs').then((response) => print(response.body));
It's best practice to return the Future from the function that uses get():
Future getAndParse(String uri) {
  return http.get('http://example.com/hugs')
      .then((response) => JSON.parse(response.body));
}
Unfortunately, I couldn't find any formal docs. So I had to look through the code (which does have good comments): https://code.google.com/p/dart/source/browse/trunk/dart/pkg/http/lib/http.dart
