可以使用 API GET 但不能使用 API POST

我正在 VS 2013 中处理现有的 Windows 服务项目。

我添加了一个 Web API 控制器类，我现在不记得它是 (v2.1) 还是 (v1) 控制器类....无论如何我将其称为 SyncPersonnelViaAwsApiController

我试图从 AWS lambda 调用它...所以如果我调用 GET

public string Get(int id)
    {
        return "value";
    }

与 const req = https.request('https://actualUrlAddress/api/SyncPersonnelViaAwsApi/Get/4 https://actualUrlAddress/api/SyncPersonnelViaAwsApi/Get/4', (res) => {

I get returned body: undefined"value"哪个是对的。 但是如果我尝试打电话

const req = https.request('https://actualUrlAddress/api/SyncPersonnelViaAwsApi/SapCall', (res) => {

I get returned body: undefined{"Message":"The requested resource does not support http method 'GET'."}

 //// POST api/<controller>
    public string SapCall([FromBody]string xmlFile)
    {
        string responseMsg = "Failed Import User";

        if (!IsNewestVersionOfXMLFile(xmlFile))
        {
            responseMsg = "Not latest version of file, update not performed";
        }
        else
        {
            Business.PersonnelReplicate personnelReplicate = BusinessLogic.SynchronisePersonnel.BuildFromDataContractXml<Business.PersonnelReplicate>(xmlFile);
            bool result = Service.Personnel.SynchroniseCache(personnelReplicate);

            if (result)
            {
                responseMsg = "Success Import Sap Cache User";
            }
        }

        return "{\"response\" : \" " + responseMsg + " \" , \"isNewActiveDirectoryUser\" : \" false \"}";
    }

有谁知道为什么它适用于 GET 而不是 POST？

因为我们可以点击 get，所以我确信它不是 lambda，但我已经将其包含在内，以防万一

const AWS = require('aws-sdk');
const https = require('https');
var s3 = new AWS.S3();
var un;
var pw;
var seralizedXmlFile;


let index = function index(event, context, callback) {

    // For the purpose of testing I have populated the bucket and key params with objects that already exist in the S3 bucket  
    var params = {
    Bucket: "testbucketthur7thdec",
    Key: "personnelData_50312474_636403151354943757.xml"
};


// Get Object from S3 bucket and add to 'seralizedXmlFile'
s3.getObject(params, function (data, err) {
    console.log("get object from S3 bucket");
    if (err) {
        // an error occurred
    }
    else
    {
        console.log("data " + data);
        // populate seralizedXmlFile with data from S3 bucket
        let seralizedXmlFile = err.Body.toString('utf-8'); // Use the encoding necessary
        console.log("objectData " + seralizedXmlFile);
    }

});

    // set params
    var ssm = new AWS.SSM({ region: 'Usa2' });
    console.log('Instatiated SSM');
    var paramsx = {
        'Names': ['/Sap/ServiceUsername', '/Sap/ServicePassword'],
        'WithDecryption': true
    };

// password and username
    ssm.getParameters(paramsx, function (err, data) {
        console.log('Getting parameter');
        if (err) console.log(err, err.stack); // an error occurred
        else {
            console.log('data: ' + JSON.stringify(data));           // successful response
            console.log('password: ' + data.Parameters[0].Value);
            console.log('username: ' + data.Parameters[1].Value);
            pw = data.Parameters[0].Value;
            un = data.Parameters[1].Value;
        }


        // request to external api application & remove dependency on ssl
        process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

        //POST DOES NOT WORK
        const req = https.request('https://actualUrlAddress/api/SyncPersonnelViaAwsApi/SapEaiCall', (res) => {
        //GET WORKS
       // const req = https.request('https://actualUrlAddress/api/SyncPersonnelViaAwsApi/Get/4', (res) => {

            res.headers + 'Authorization: Basic ' + un + ':' + pw;
            let body = seralizedXmlFile;
            console.log('seralizedXmlFile: ' + seralizedXmlFile); 
            console.log('Status:', res.statusCode);
            console.log('Headers:', JSON.stringify(res.headers));

            res.setEncoding('utf8');
            res.on('data', (chunk) => body += chunk);
            res.on('end', () => {
                console.log('Successfully processed HTTPS response');
                callback(null, body);
                console.log('returned body:', body);

            });
        });
        req.end();
    });
};
exports.handler = index;

UPDATE感谢@Thangadurai 的帖子AWS Lambda - NodeJS POST 请求和异步写入/读取文件 https://stackoverflow.com/questions/32636956/aws-lambda-nodejs-post-request-and-asynch-write-read-file

我能够包含 post_options...请参阅更新的 lambda

          // An object of options to indicate where to post to
    var post_options = {
        host: 'https://actualUrlAddress',
        port: '80',
        path: '/api/SyncPersonnelViaAwsApi/SapEaiCall',
        method: 'POST',
        headers: {
            'Content-Type': 'application/json',
            'Content-Length': post_data.length
        }
    };

 const req = https.request(post_options, (res) => {
   res.headers + 'Authorization: Basic ' + un + ':' + pw;
            let body = seralizedXmlFile;
            console.log('seralizedXmlFile: ' + seralizedXmlFile); 
            console.log('Status:', res.statusCode);
            console.log('Headers:', JSON.stringify(res.headers));

            res.setEncoding('utf8');
            res.on('data', (chunk) => body += chunk);
            res.on('end', () => {
                console.log('Successfully processed HTTPS response');
                callback(null, body);
                console.log('returned body:', body);

            });
        });
        req.end();

现在它被标记为错误：

Error: getaddrinfo ENOTFOUND http://actualUrlAddress http://actualUrlAddress.private:80

我之前遇到过 getaggrinfo ENOTFOUND 错误，这意味着它找不到地址....但主机名和 api 路径是否正确？

我正在努力达到

const req = https.request('https://actualUrlAddress/api/SyncPersonnelViaAwsApi/SapCall

是的，端口是 80

任何帮助，将不胜感激 塔 中号

直接跳到更新部分（据我所知，其他所有内容都不相关）。选项应如下所示：

var post_options = {
    host: 'actualUrlAddress',
    protocol: 'https:'
    port: '443',
    path: '/api/SyncPersonnelViaAwsApi/SapEaiCall',
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Content-Length': post_data.length
    }
};

由于作为文档 https://nodejs.org/api/http.html#http_http_request_options_callbackstates、host和protocol是两个独立的属性，SSL端口不太可能是80，通常是443。
