Locust: sending POST image in client.post() never receives Request.FILES

[anujacharya1]

I tried to use locust client to upload a file but I always get request.FILES.get('photo')=None on server side (If I use POSTMAN I am getting the file)

@task
def post_img(self):
    with open('img.jpg', 'rb') as image:
        payload = {'id': self.id, 'photo': image}
        upload_result = self.client.post("/image/", payload)

Also tried the following:

@task
def post_img(self):
    with open('img.jpg', 'rb') as image:
        payload = {'id': self.id}
        upload_result = self.client.post("/image/", data=payload, files=image)

Try specifying the name of the field for files

@task
def post_img(self):
    with open('img.jpg', 'rb') as image:
        self.client.post(
            "/image/",
            data={'id': self.id},
            files={'photo': image}
        )
