我将无服务器框架与javascript一起使用。
我的代码是:
import { App } from '../lib/App';
export const hello = (event, context, cb) => {
context.callbackWaitsForEmptyEventLoop = false;
// This resolved promise would be be in the application library code in a real-world application and provide the results
App.handleFirst(event) // eslint-disable-line promise/catch-or-return
.then(result => ({
statusCode: 200,
headers: {
'Content-Type': 'application/json;charset=utf-8'
},
body: JSON.stringify(result)
}))
.asCallback(cb);
return;};
在App.js内部
import BbPromise from 'bluebird';
const THE_MESSAGE = 'Hello from the webpack 4 sample';
export class App {
static handleFirst(event) {
const myDemoResult = {
message: App.THE_MESSAGE,
from: 'First lambda ',
event
};
console.info(myDemoResult);
return BbPromise.resolve(myDemoResult);
}
我使用其他命令来部署它。
set SLS_DEBUG=*
severless deploy
我的错误是:

Unexpected token A in JSON at position 0
For debugging logs, run again after setting the "SLS_DEBUG=*" environment variable.

为什么json第一个元素错误?如何查看json字符串?
答案 0 :(得分:0)
看到您的serverless.yml文件后,我相信问题可能出在webpack.config.js
文件中。可能值得尝试更改您的custom
部分,并用引号引起来:'webpack.config.js'
。喜欢:
custom:
webpack:
webpackConfig: 'webpack.config.js'
includeModules: true
我认为问题出在您的App.js类中:
const myDemoResult = {
message: App.THE_MESSAGE,
from: 'First lambda ',
event
};
您的JSON结构无效;在传递对象事件的地方,没有给它提供键/名称。您可能想要类似的东西:
const myDemoResult = {
message: App.THE_MESSAGE,
from: 'First lambda ',
event: event
};
常量THE_MESSAGE
不在App
类中。您应该这样将其移至App
类{..}
内:
export class App {
static get THE_MESSAGE() { return 'Hello from the webpack 4 sample'; }
