The Content-Type error occurs when the phpcurl under RedHat uploads an image.

RedHat6 + Nginx + PHP environment, use PHPCURL to upload the image to kaixinnet, the MIME type of the image is incorrect, as follows: ---------------------------- bcf414c27670Content-Disposition: form-data; name = "file1 "; filename = "/tmp/dog.jpg" Content-Type: application

In the RedHat 6 + Nginx + PHP environment, use php curl to upload an image to kaixin.com. The MIME type of the image is incorrect, as shown below:

------------------------------ Bcf414c27670

Content-Disposition: form-data; name = "file1"; filename = "/tmp/dog.jpg"

Content-Type: application/octet-stream

If the Content-Type is not image/jpeg, the upload fails.

This problem is solved by adding "; type = image/jpeg" after the file name, such as 'file' => '@/test.jpg; type = image/jpeg'

7.19.7 supports this method. 7.16.0 does not support this method.
