详解HTTP GET请求

实例1：NodeMcu通过TCP实现HTTP GET请求（无请求主体）

srv = net.createConnection(net.TCP, 0)
srv:on("receive", function(sck, c) print(c) end)
srv:connect(80,"fanyi.youdao.com")
srv:on("connection", function(sck, c)

  sck:send("GET /openapi.do?keyfrom=NodeMcu&key=1067687977&type=data&doctype=json&version=1.1&q=good HTTP/1.1\r\nHost: fanyi.youdao.com\r\n\r\n")

end)

实例2：NodeMcu通过TCP实现HTTP POST请求（有请求主体）

srv = net.createConnection(net.TCP, 0)
srv:on("receive", function(sck, c) print(c) sck:close() end)
srv:connect(80,"www.tuling123.com")
srv:on("connection", function(sck, c)

--%E4%BD%A0%E5%A5%BD为汉字“你好”的UTF8编码    
    json = cjson.encode( {key="d6f699f259941e09ac06ecee6001d584",info="%E4%BD%A0%E5%A5%BD",userid="123456"} )

    length = string.len(json)
    
        sck:send("POST /openapi/api  HTTP/1.1\r\nHost: www.tuling123.com\r\nContent-length: "..length.."\r\nConnection: close\r\n\r\n"
          ..json.."\r\n")
end)
