函数文档

func get(url, headers?)

用GET方法请求指定url的资源，返回一个Bytes值

若请求失败时，抛出异常

func getJson(url, headers?)

用GET方法请求指定url的资源，并将返回内容按json格式解析为一个ZGG的值

若请求失败时，抛出异常

func postForm(url, form, headers?)

以x-www-form-urlencoded方式往指定URL发起一次Post Form请求。若请求失败则抛出异常。

Examples

zgg> @http.postForm('https://httpbin.org/post', {
....   name: 'zgg',
....   values: [1, 2, 3],
.... }, {
....   Authorization: 'Bearer HelloWorld',
.... })
{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {
    "name": "zgg", 
    "values": [
      "1", 
      "2", 
      "3"
    ]
  }, 
  "headers": {
    "Accept-Encoding": "gzip", 
    "Authorization": "Bearer HelloWorld", 
    "Content-Length": "35", 
    "Content-Type": "application/x-www-form-urlencoded", 
    "Host": "httpbin.org", 
    "User-Agent": "Go-http-client/2.0", 
    "X-Amzn-Trace-Id": "Root=1-62b404ea-7271f822152de246228bd973"
  }, 
  "json": null, 
  "origin": "137.59.101.43", 
  "url": "https://httpbin.org/post"
}

func postJson(url, jsonValue, headers?)

往指定URL发起一次Post Json请求。若请求失败则抛出异常。

Examples

zgg> @http.postJson('https://httpbin.org/post', {
....   name: 'zgg',
....   values: [1, 2, 3],
.... }, {
....   'X-My-Header': 'My Value lalala',
.... })
{
  "args": {}, 
  "data": "{\"name\":\"zgg\",\"values\":[1,2,3]}", 
  "files": {}, 
  "form": {}, 
  "headers": {
    "Accept-Encoding": "gzip", 
    "Content-Length": "31", 
    "Content-Type": "application/json", 
    "Host": "httpbin.org", 
    "User-Agent": "Go-http-client/2.0", 
    "X-Amzn-Trace-Id": "Root=1-62b40554-306f51a40a6b9ee901489c05", 
    "X-My-Header": "My Value lalala"

  "origin": "137.59.101.43", 
  "url": "https://httpbin.org/post"
}

type Request

func serve(listenAddr, handleFunc)

功能：启动一个web服务器，监听listenAddr地址（格式同go的http.ListenAndServe的第一个参数），并用handleFunc处理每个请求。

serve函数是一个非常简便的提供http服务的方法，适用于对外提供简单服务。
