Is it wrong to modify the Cookie of headers?

Modifying the headers cookie in postman or curl does not work. Does it prove that the cookie cannot be passed through headers? Must the passed cookie exist locally, what is this process?

Modifying headers cookies in postman or curl does not work, proving that Cookies cannot be passed through headers.
So must the passed cookie exist locally? What is the process?

For example

Curl works. The code written earlier is incorrect. But postman is still invalid. Should it be a plug-in problem or?

This problem is caused by the postman plug-in. What I installed earlier should not be a real postman.

The second is the real postman, and the first is a bug.

Postman is a browser-based plug-in that sends requests by callingajax/xmlhttprequestThis method is bound to browser security restrictions:

1. First, XMLHttpRequest does not support cross-origin for security reasons. postman has declared to the browser that cross-origin permissions are required.

1. Secondly, some headers cannot be set in the browser due to security reasons, and are subject to the user features of the browser.

Which headers cannot be set?XMLHttpRequest.jsSource code implementation

var forbiddenRequestHeaders = [    "accept-charset",    "accept-encoding",    "access-control-request-headers",    "access-control-request-method",    "connection",    "content-length",    "content-transfer-encoding",    "cookie",    "cookie2",    "date",    "expect",    "host",    "keep-alive",    "origin",    "referer",    "te",    "trailer",    "transfer-encoding",    "upgrade",    "via"   ];

1. The first is the Postman plug-in, and the second is the Postman App.

2. Restricted by the Chrome sandbox mechanism, only cookies written by the browser can be transmitted. To bypass the browser, you can only use the Postman App and enable another plug-in Interceptor. Https://chrome.google.com/webstore/detail/postman-interceptor/aicmkgpgakddgnaphhhpliifpcfhicfo

3. However, this App is still incomplete and the Cookie value cannot be found .. You can only clear all cookies in Chrome ..

4. The Cookie format you wrote is not correct either. Enter the Cookie on the left and the name = value on the right.
