Pact.io (машинопись) терпит неудачу, если присутствуют и заголовки и тело

/ 08 января 2019

Я использую Pact.io для контрактов между моим внешним интерфейсом (TypeScript) и внутренним. Я пытаюсь написать договор для загрузки файла; однако, если я укажу и headers.Content-Type, и body в разделе withRequest, проверка завершится неудачно без видимой причины (в веб-интерфейсе -> договор даже не генерируется). Если я пропускаю любой из этих двух разделов, проверка работает (но, конечно, некоторые данные отсутствуют, поэтому я не могу успешно проверить бэкэнд). Моя установка выглядит так: 

const fileBody = '------boundary\r\n' +
    'Content-Disposition: form-data; name="file"; ' +
    'filename="test-attachment.pdf"\r\n' +
    'Content-Type: application/pdf\r\n' +
    '\r\n' +
    'file content\r\n' +
    '------boundary--\r\n';
const likeFileBody = fileBody.replace(/boundary/g, ".*");
const interaction: InteractionObject = {
    state: "my state",
    uponReceiving: "a file upload",
    withRequest: {
        method: 'POST',
        path: `/my/upload/path`,
        headers: {
            "Content-Type": Matchers.regex({
                generate: "multipart/form-data; boundary=----boundary",
                matcher: "multipart/form-data; boundary=.*",
            })
        },
        body: Matchers.regex({
            generate: fileBody,
            matcher: likeFileBody,
        }),
    },
    willRespondWith: {
        status: 201,
        headers: {'Content-Type': 'application/json'},
        body: {"some": "data"},
    }
};
await provider.addInteraction(interaction);

// ng2-file-upload module
const uploader = new FileUploader({
    url: `/my/upload/path`
});

uploader.addToQueue([new File(["file content"], "test-attachment.pdf")]);
uploader.uploadAll();
// poll uploader status
return new Promise(async resolve => {
    while (uploader.isUploading) {
        await new Promise((pollResolve => setTimeout(pollResolve, 10)));
    }
    resolve();
});

Журнал пакта говорит следующее:

Я что-то упустил или это ошибка в pact framework?

Изучив исходный код платформы pact, я обнаружил, что она уже заменяет границу подстановочным знаком; однако это происходит только в теле, а не в заголовке Content-Type. Следовательно, правильная формулировка для пакта: 

const fileBody = '------boundary\r\n' +
    'Content-Disposition: form-data; name="file"; ' +
    'filename="test-attachment.pdf"\r\n' +
    'Content-Type: application/pdf\r\n' +
    '\r\n' +
    'file content\r\n' +
    '------boundary--\r\n';

...

headers: {
    "Content-Type": Matchers.regex({
        generate: "multipart/form-data; boundary=----boundary",
        matcher: "multipart/form-data; boundary=.*",
    })
},
body: fileBody,

С этим я смог проверить как у потребителя, так и у поставщика.

В настоящее время нельзя применять сопоставления тела для типов содержимого, отличных от JSON.

Официальное руководство заключается в тестировании других аспектов взаимодействия, но не самой двоичной полезной нагрузки: https://docs.pact.io/faq#how-do-i-test-binary-files-in-responses-such-as-a-download
