AWS Lambda Go函数在通过API GW调用时未获取请求正文

HTTP request body not getting to AWS lambda function via AWS API Gateway 或 Getting json body in aws Lambda via API gateway

然而,这些问题都没有解决使用Golang的问题,我一直面临的问题是找到一个等价的 event

这是我的Lambda函数:

package main

import (
    "context"
    "encoding/json"
    "github.com/aws/aws-lambda-go/lambda"
    "github.com/aws/aws-lambda-go/events"
    "log"
)

type MyReturn struct {
    Response string `json:"response"`
}

type APIGWResponse struct {
    IsBase64Encoded bool              `json:"isBase64Encoded"`
    StatusCode      int               `json:"statusCode"`
    Headers         map[string]string `json:"headers"`
    Body            string            `json:"body"`
}

func handle(ctx context.Context, name MyReturn) (APIGWResponse, error) {
    log.Print("Called by ", name)
    log.Print("context ", ctx)
    headers := map[string]string{"Access-Control-Allow-Origin": "*", "Access-Control-Allow-Headers": "Origin, X-Requested-With, Content-Type, Accept"}

    code := 200
    response, error := json.Marshal(myReturn{Response:"Hello, " + name.Body})
    if error != nil {
        log.Println(error)
        response = []byte("Internal Server Error")
        code = 500
    }

    return APIGWResponse{true, code, headers, string(response)}, nil
}

func main() {
    lambda.Start(handle)
}

MyReturn 从API GW调用时,对象未填充任何值。线路 log.Print("Called by ", name) 结果不会将任何内容附加到 Called by 字符串。

请求API GW:

 POST -> body: '{"name":"Bob"}', headers: {'Content-Type': 'application/json'}

这是在纯JS中执行的,如下所示:

const BASE_URL = "https://my_api_id.execute-api.us-east-1.amazonaws.com/prod/";
const TRIGGER_URL = "my_lambda_function";

function toGW() {
    fetch(BASE_URL + TRIGGER_URL, {
        method: 'POST',
        body: '{"name":"Bimesh"}',
        headers:{
            'Content-Type': 'application/json'
        }
    })
    .then(data => data.json())
    .then(json => console.log(json))
    .catch(error => console.log(error));
}

然而,当从AWS Lambda控制台测试它时,完全相同的身体工作。

{"name":"Bob"}
