No match for request POST even nock successfully matched request

How real request data looks like:

{ 
  port: 443,
  path: '/',
  host: 'dynamodb.us-east-1.amazonaws.com:443',
  hostname: 'dynamodb.us-east-1.amazonaws.com',
  method: 'POST',
  headers:  {
     'user-agent': 'aws-sdk-nodejs/2.2.48 darwin/v4.4.3',
     'content-type': 'application/x-amz-json-1.0',
     'x-amz-target': 'DynamoDB_20120810.ListTables',
     'x-amz-content-sha256': '...',
     'content-length': 2,
     host: 'dynamodb.us-east-1.amazonaws.com',
     'x-amz-date': '...',
     authorization: '…'
   },
  body: '{}' 
}

How im trying to match this request with nock:

nock('https://dynamodb.us-east-1.amazonaws.com', {
  reqheaders: {
    'x-amz-target': 'DynamoDB_20120810.ListTables'
  }
})
.post('/', {})
.reply(503, 'The service is currently unavailable or busy.')
.log((data) => console.log(data))

From log statement, i can see that nock is able to match this request: matching https://dynamodb.us-east-1.amazonaws.com:443 to POST https://dynamodb.us-east-1.amazonaws.com:443/: true, but im not receiving 503, 'The service is currently unavailable or busy.', but error: 'Nock: No match for request POST https://dynamodb.us-east-1.amazonaws.com/ {}'

I think I ran into a similar issue. Its not clear from the documentation how to use nock when you specify the entire url in the initial nock params(In my case because the URL comes from env). If you pass ‘/’ into the post it wont match properly(first thing I tried as well) and it also fails if you dont pass anything. I found it only worked after passing a empty string.

var nock = require('nock');
var request = require('request');

// Errors out
nock('http://localhost/path').post().reply(200);

request.post('http://localhost/path', function(err, body) {
  console.log(err, body);
});

//Also errors out
nock('http://localhost/path').post('/').reply(200);

request.post('http://localhost/path', function(err, body) {
  console.log(err, body);
});

//Works as intended.
nock('http://localhost/path').post('').reply(200);

request.post('http://localhost/path', function(err, body) {
  console.log(err, body);
});

Maybe there could be a doc update? Or maybe its specified somewhere and I just missed it…

Though it’s very late to reply on this but it will surely help the new explorers.

Just use persist() for this, as the docs say

When you setup an interceptor for a URL and that interceptor is used, it is removed from the interceptor list. This means that you can intercept 2 or more calls to the same URL and return different things on each of them. It also means that you must setup one interceptor for each request you are going to have, otherwise nock will throw an error because that URL was not present in the interceptor list. If you don’t want interceptors to be removed as they are used, you can use the .persist() method.

nock("https://abc.co")
    .persist()
    .get("/getresponse")
  .delayBody(1000)
  .reply(200, {
   name:"Sunil Lulla",
   "jobRole":"SoftwareDeveloper"
  });

Hope it will help you 😄
