Question

我正在尝试在aws lambda上托管一个laravel应用程序，并使用aws api网关调用它的路由。该应用程序基本上是一个Web爬虫，它从rss提要中获取网页。

当我使用api网关生成的网址拨打laravel路线时，laravel会将请求重定向到＆＃39; / home＆＃39;路径。但是，当我使用＆＃34;节点调试＆＃34;在ec2实例上测试它时，它就像一个魅力。以下是我所遵循的步骤的详细信息。

我跟随了一篇由Chris White撰写的精彩博客，用于在aws lambda上托管laravel应用程序。

步骤：

生成PHP CGI二进制文件

我用过＆＃34; amzn-ami-hvm-2016.03.3.x86_64-gp2＆＃34; ec2实例构建我的php-cgi二进制文件

./ configure --prefix = / tmp / php-7.0.11 / compiled / --without-pear --enable-shared = no --enable-static = yes --enable-phar --enable-json --disable-all --with-openssl --with-curl --enable-libxml --enable-simplexml - -enable-xml --with-mhash --with-gd --enable-exif --with-freetype-dir --enable-mbstring --enable-sockets --enable-pdo --with-pdo-mysql - enable-tokenizer --enable-session --enable-filter

NodeJS Lambda函数产生PHP CGI进程 - php.js 文件

＆＃13;

process.env['PATH'] = process.env['PATH'] + ':' + process.env['LAMBDA_TASK_ROOT'];

var parser = require('http-string-parser');
var spawn = require('child_process').spawn;
exports.handler = function(event, context) {

  var requestMethod = event.httpMethod || 'GET';
  var serverName = event.headers ? event.headers.Host : '';
  var requestUri = event.path || '';
  var headers = {};

  if (event.headers) {
    Object.keys(event.headers).map(function(key) {
      headers['HTTP_' + key.toUpperCase()] = event.headers[key];
    });
  }

  var request_env = Object.assign({
    REDIRECT_STATUS: 1,
    REQUEST_METHOD: requestMethod,
    SCRIPT_FILENAME: 'api/public/index.php',
    SCRIPT_NAME: '/index.php',
    PATH_INFO: '/',
    SERVER_NAME: serverName,
    SERVER_PROTOCOL: 'HTTP/1.1',
    REQUEST_URI: requestUri
  }, headers);

  var php = spawn('./php-cgi', ['api/public/index.php'], {
    env: request_env
  });

  var response = '';

  php.stdout.on('data', function(data) {
    response += data.toString('utf-8');
  });

  php.stderr.on('data', function(data) {
    console.log("STDERR: " + data.toString());
  });

  php.on('close', function(code) {

    var parsedResponse = parser.parseResponse(response);
    context.succeed({
      isBase64Encoded: false,
      statusCode: parsedResponse.statusCode || 200,
      headers: parsedResponse.headers,
      body: parsedResponse.body
    });

  });

}

准备AWS Lambda软件包

HelloLambda.zip 捆绑包的目录结构是

├──api

├──node_modules

├──php-cgi

└──php.js

api文件夹由我的laravel应用程序组成。

API网关 - 我为HelloLambda函数创建了一个api网关。 api有联盟＆amp;通道作为路径参数。 GET方法使用lambda代理集成。 api在阶段视图中显示以下url

的https：//***.execute-api.us-east-1.amazonaws.com/prod/HelloLambda/espnheadlinesimage/ {联赛} / {信道}

api-gateway-screenshot.jpg

向api发出GET请求，提供联盟和频道参数。

的https：//***.execute-api.us-east-1.amazonaws.com/prod/HelloLambda/espnheadlinesimage/nhl/28

当我发出此请求时，浏览器会显示一条消息

重定向到http：//***.execute-api.us-east-1.amazonaws.com/home

我的laravel routes.php文件包含以下路径

Route::get('espnheadlinesimage/{league}/{channel}', 'EspnController@headlinesimage');

任何帮助都将受到高度赞赏。提前谢谢。

这是我的测试API调用中我的事件对象内容的控制台输出

Answer 1

我对laravel一无所知，但您已为espnheadlinesimage/....配置了路线，但实际上是通过API GW呼叫路由HelloLambda/espnheadlinesimage/{league}/{channel}。 Lambda函数中requestUri（和event.path）的值将在您的测试API调用中为HelloLambda/espnheadlinesimage/nhl/28。

Answer 2

此问题已按照Jack的建议解决。

问题是API网关生成的API网址是

/ HelloLambda / espnheadlinesimage / {联赛} / {信道}

然而，我的Laravel路线文件中的路线是

/ espnheadlinesimage / {联赛} / {信道}

我的误解是lambda函数的基本URL是

的https：//***.execute-api.us-east-1.amazonaws.com/prod/HelloLambda/

我应该在这条路径之后添加路线到我的laravel路线文件，即

/ espnheadlinesimage / {联赛} / {信道}

但是，我的路径文件中的路径应该包含＆＃39; / HelloLambda＆＃39; ，即它应该是

/ HelloLambda / espnheadlinesimage / {联赛} / {信道}
