問題描述
我正在嘗試將我從服務(wù)器獲取的 XML 字符串轉(zhuǎn)換為我的 Lambda 函數(shù)中的 JSON.
我已經(jīng)設(shè)置了這個相當(dāng)簡單的示例來模擬我使用 DynamoDB 從服務(wù)器獲得的 XML 答案.(目前我只是在嘗試進(jìn)行轉(zhuǎn)換)
I am trying to convert an XML String that I get from a server to JSON inside my Lambda function.
I have set up this rather simple example to simulate the XML answer that i get from the server using DynamoDB. (Currently I'm just trying to get the convertion going)
'use strict';
var AWS = require('aws-sdk');
var docClient = new AWS.DynamoDB.DocumentClient({region: 'eu-west-1'});
exports.handler = function (e, ctx, callback){
let table = "dsbTable";
let bpNumber = 1337;
var test;
var x2js = new X2JS();
let params = {
TableName: table,
Key:{
"bpNumber": bpNumber
},
};
docClient.get(params, function(err, data) {
if (err) {
console.error("Unable to read item. Error JSON:", JSON.stringify(err, null, 2));
callback(err, null);
} else {
console.log("GetItem succeeded:", JSON.stringify(data, null, 2));
console.log('test' +data.Item.getBp);
//var jsonObj = x2js.xml_str2json(data.Item.getBp);
//console.log(jsonObj);
callback(null, data);
}
});
} ;
獲取項目工作正常，并像這樣返回
getting the item works just fine and is returned like this
{
"Item": {
"getBp": "<message version="1.0" system="AVS/3"><header><client>553</client><avs3-sales-organization>7564</avs3-sales-organization><avs3-service-provider>DSD</avs3-service-provider></header><body><business-partner><salutation-code>01</salutation-code><titel-code-academic/><titel-academic/><titel-code-royal/><titel-royal/><job-titel/><last-name1>Pickle</last-name1><last-name2/><first-name>N</first-name><street/><street-suffix/><street-number/><street-number-suffix/><address-line-1>10 Waterside Way</address-line-1><address-line-2/><address-line-3/><zipcode>NN4 7XD</zipcode><country-code>GB</country-code><city>NORTHAMPTON</city><district/><region-code>NH</region-code><region-text>Northamptonshire</region-text><company1/><company2/><company3/><department/><po-box/><po-box-zipcode/><po-box-city/><po-box-country-code/><major-customer-zipcode/><address-source/><advertisement>Y</advertisement><category/><bp-number>1100000772</bp-number><bp-number-external/><bp-group>ABON</bp-group><eu-sales-tax-number/><bic-master-number/><sector/><communication><communication-type>WW</communication-type><communication-value>kate.southorn@dsbnet.co.uk</communication-value><communication-default>Y</communication-default></communication><attribute><attribute-type>ACC</attribute-type><attribute-value>Y</attribute-value></attribute><attribute><attribute-type>OIEMEX</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OINLIN</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OISMEX</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OISMIN</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OOEMIN</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OOFXEX</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OOFXIN</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OOPTEX</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OOPTIN</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OOTEEX</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>OOTEIN</attribute-type><attribute-value>N20121211</attribute-value></attribute><attribute><attribute-type>THEDSU</attribute-type><attribute-value/></attribute></business-partner></body></message>",
"bpNumber": 1337
}
}
我現(xiàn)在的主要問題是我不知道如何導(dǎo)入任何 XMLtoJSON 庫文件，例如 這里的這個
My main issue now is that I can not figure out how i can import any XMLtoJSON library files like this one here
我希望我在這種情況下的代碼不是完全沒有價值，并且有一個相當(dāng)簡單的解決方案.
I hope my code in this case is not completely worthless and there is a rather simple solution.
推薦答案
您正在經(jīng)歷許多新的 Lambda 用戶所走過的道路.
You're going through the path that many new Lambda users have gone.
使用 Lambda，這非常簡單，您只需編寫代碼并驗證它是否按預(yù)期工作 - 我的意思是在您的計算機(jī)上.
With Lambda, it is absolutely easy, you just write your code and validate that it works as expected - I mean on your computer.
驗證后，請執(zhí)行以下操作:
Once you have validated it, do as follows:
- 壓縮整個文件夾的內(nèi)容，包括
node_modules目錄以及您使用的任何依賴項. - 將其上傳到 Lambda.
如果您不小心也壓縮了包含文件夾，那很好，只需確保更新 Lambda 以從以下位置運(yùn)行腳本:dir_name/file_name.function_name(不要不要忘記從你的模塊中導(dǎo)出 function_name).
If you accidentally zipped the containing folder as well, that is fine, just make sure to update Lambda to run the script from: dir_name/file_name.function_name (don't forget to export function_name from your module).
