我正在使用Node.js和Restify構建API。我正在嘗試使用Supertest和Tape進行功能端點測試。我有一個連續兩次調用API的測試，它說我發送後無法設置標題。Supertest + Tape + Restify - 連續調用時無法設置頭兩次錯誤
UserController.js
/*
* Create a user.
*/
exports.store = function(req, res, next) {
// Get request input.
var firstName = ParsesRequest.getValue(req, 'firstName'),
lastName = ParsesRequest.getValue(req, 'lastName'),
email = ParsesRequest.getValue(req, 'email'),
password = ParsesRequest.getValue(req, 'password');
// Create command.
var command = new CreateUserCommand(firstName, lastName, email, password);
// Execute command.
CommandBus.execute(command, function(error, data) {
var hasError = !!error && !data,
status,
message;
status = (!hasError) ? StatusCodes.Created : StatusCodes.InternalServerError;
message = (!hasError) ? UserTransformer.transform(data) : error;
res.json(status, message);
});
}
CreatesUserApiTest.js
var test = require('tape');
var CreatesFakeUser = require('../../helpers/CreatesFakeUser');
var request = require('supertest');
var config = require('../../../config/Config').getConfiguration('test');
var url = 'http://' + config.url + ':' + config.port;
test('Creates two users with same email and returns error', function(assert) {
var user = CreatesFakeUser.generate();
request(url)
.post('/user')
.set('Accept', 'application/json')
.send(user)
.expect(201)
.end(function(err, res){
assert.equals(res.status, 201, 'Returns 201 as status code.');
assert.equals(!!res.body.id, true, 'Result body has an id field.');
});
request(url)
.post('/user')
.set('Accept', 'application/json')
.send(user)
.expect(500)
.end(function(err, res){
assert.equals(res.status, 500, 'Returns 500 because user already exists.');
assert.end();
});
});
有沒有人有，爲什麼第二次請求失敗的任何想法？我只在我的方法中發送一次res.json，所以它似乎不應該設置標頭兩次。另外，我不確定它是否與設置標題上的連接關閉有關，但我嘗試了，但它無濟於事。也許它與異步有關。
任何幫助，將不勝感激！
