编写函数

操作步骤

1. 登录函数计算控制台。
2. 在顶部菜单栏，选择地域。
3. 在左侧导航栏，单击服务/函数。
4. 找到目标服务下的目标函数，单击函数名称。
   
5. 单击代码执行页签，在代码编辑器中编写代码。
   代码示例如下：

   Node.js Python PHP

   var getRawBody = require('raw-body')
   module.exports.handler = function (request, response, context) {
       // get request info
       getRawBody(request, function (err, data) {
           var params = {
               path: request.path,
               queries: request.queries,
               headers: request.headers,
               method: request.method,
               body: data,
               url: request.url,
               clientIP: request.clientIP,
           }
           // you can deal with your own logic here
           // set response
           var respBody = new Buffer.from(JSON.stringify(params));
           // var respBody = new Buffer( )
           response.setStatusCode(200)
           response.setHeader('content-type', 'application/json')
           response.send(respBody)
       })
   };

   # -*- coding: utf-8 -*-
   import json
   HELLO_WORLD = b"Hello world!\n"
   def handler(environ, start_response):
       request_uri = environ['fc.request_uri']
       response_body = {
         'uri':environ['fc.request_uri'],
         'method':environ['REQUEST_METHOD']
       }
       # do something here
       status = '200 OK'
       response_headers = [('Content-type', 'text/json')]
       start_response(status, response_headers)
       # Python2
       return [json.dumps(response_body)]
       # Python3 tips: When using Python3, the str and bytes types cannot be mixed.
       # Use str.encode() to go from str to bytes
       # return [json.dumps(response_body).encode()]

   <?php
   use RingCentral\Psr7\Response;
   function handler($request, $context): Response{
       /*
       $body       = $request->getBody()->getContents();
       $queries    = $request->getQueryParams();
       $method     = $request->getMethod();
       $headers    = $request->getHeaders();
       $path       = $request->getAttribute("path");
       $requestURI = $request->getAttribute("requestURI");
       $clientIP   = $request->getAttribute("clientIP");
       */
       return new Response(
           200,
           array(
               "custom_header1" => "v1",
               "custom_header2" => ["v2", "v3"],
           ),
           "hello world"
       );
   }
