使用Supertest，我可以创建一个默认设置了一些标头的替代请求吗？

I am using Supertest with Mocha to test an API developed with Node JS.

我正在使用Supertest和Mocha来测试用Node JS开发的API。

And I want to do a lót of different tests on the API. With almost all of them I have to set Authorization and Content-Type headers again (because the API requires them for this test).

我想对API进行不同的测试。几乎所有这些都必须再次设置Authorization和Content-Type标头（因为API要求它们进行此测试）。

it('Creation without an email address should fail and return error code 50040', function(done) {
  request
    .post('/mpl/entities')
    .set('Authorization', 'Token 1234567890') //set header for this test
    .set('Content-Type',  'application/json') //set header for this test
    .send({
      firstname: "test"
    })
    .expect('Content-Type', /json/)
    .expect(500)
    .expect(anErrorCode('50040'))
    .end(done);
});

it('Creation with a duplicate email address should fail and return error code 50086', function(done) {
  request
    .post('/mpl/entities')
    .set('Authorization', 'Token 1234567890') //<-- again
    .set('Content-Type',  'application/json') //<-- again, I'm getting tired
    .send({
      email: "[e-mail]"
    })
    .expect('Content-Type', /json/)
    .expect(500)
    .expect(anErrorCode('50086'))
    .end(done);
});

Can I create an alternative request with those headers set by default?

我可以使用默认设置的标头创建替代请求吗？

3 个解决方案

#1

If i remember correctly in superagent one can pass a hash to set

如果我在superagent中记得正确，可以传递哈希来设置

.set({key:value,key2:value2})

let me know if it doesnt work with supertest.

让我知道它是否与supertest不起作用。

You could use a common routine to build your "default" headers as an object and pass them to the request:

您可以使用公共例程将“默认”标头构建为对象，并将它们传递给请求：

//# file:config.js

var config = { 
  authorization: { "Authorization":"authvalue" }
}

// Content-Type left out because supertest will use Content-Type json when you use the appropriate method

module.exports = config;

And now in your test.js:

现在在你的test.js中：

//# file:test.js

var request = require("supertest");
var config = require("./config");

request = request(config.baseUrl)
var commonHeaders = { "authorization":"TokenValueASDF" };

describe("testing", function() {
  it.should('present authorization header to server', function(done) {
    request.get('/someurl')
      .set(commonHeaders)
      .set({"X-TestSpecificHeader":"Value"})
      .expect(200,done) //if not authorized you'd get 401
  })

})

Also, if you need to have your app get that token value at runtime (most likely) see this article for using a requested token value that is generated for the tests: https://jaketrent.com/post/authenticated-supertest-tests/

此外，如果您需要让您的应用程序在运行时获取该令牌值（最有可能），请参阅本文以使用为测试生成的请求令牌值：https：//jaketrent.com/post/authenticated-supertest-tests /

You can use the library superagent-defaults as follows:

您可以使用库superagent-defaults，如下所示：

installation

npm install --save-dev supertest superagent-defaults

usage

var defaults = require('superagent-defaults');
var supertest = require('supertest');

var request = defaults(supertest(app)); // or url

// set the default headers
request.set(commonHeaders);

// use as usually
