Я создал приложение JHipster (v5.3.1), в котором есть сущность Attachment
, которая содержит поле Blob
с именем fileAttachment
.Используя сгенерированный веб-интерфейс Angular 6, я могу загружать файлы в приложение.Я хотел бы сделать то же самое, используя командную строку (HTTPie
или curl
).
Определение Attachment в jdl:
/**
* An entity to store attachments
*/
entity Attachment {
/** The name of the attachment */
fileName String required,
/** the attachment */
attachedFile Blob required
}
Генератор JHipster создает Attachment.java
и AttachmentService.java
и AttachmentResource.java
, который я совсем не модифицировал.
Используя веб-интерфейс, при загрузке файла регистрируются следующие операторы:

ИспользованиеHTTPie Я могу пройти проверку подлинности и получить токен JWT
http POST :8080/api/authenticate password=**** username=admin
Однако неясно, как POST
файл:
http -v --form POST :8080/api/attachments/ \
'Authorization:Bearer ***.***.***' \
fileName=test.txt \
attachedFile@test.txt \
attachedFileContentType=text/plain
приводит к:

Как создать POST
?
Обновление
Когда я вижу, что происходит в представлении разработчика Chrome, я вижу, что полезная нагрузка запроса
{"fileName":"test.txt","attachedFileContentType":"text/plain","attachedFile":"dGVzdCB0ZXN0IHRlc3QK"}
Непонятно, откуда берется значение attachedFile
?
