Send Image via HTTP header

[hanskallor]

Hi Forum,

I want to receive an image via http in my server.

to get the length of my header value I use:

Code: [Select all] [Expand/Collapse]

1.  size_t httpd_req_get_hdr_value_len(httpd_req_t *r, const char *field)

my problem is that the value is to long and my server throws an error (the Headers field is to long)

Code: [Select all] [Expand/Collapse]

1. W (17168) httpd_parse: parse_block: response uri/header too big
2. W (17168) httpd_txrx: httpd_resp_send_err: 431 Request Header Fields Too Large - Header fields are too long for server to interpret
3. W (17188) httpd_parse: parse_block: incomplete (0/128) with parser error = 16
4. W (17188) httpd_txrx: httpd_resp_send_err: 400 Bad Request - Server unable to understand request due to invalid syntax
5. W (17208) httpd_parse: parse_block: incomplete (0/78) with parser error = 16
6. W (17208) httpd_txrx: httpd_resp_send_err: 400 Bad Request - Server unable to understand request due to invalid syntax
7. W (17218) httpd_txrx: httpd_sock_err: error in send : 104

My question is.

How can I send a long Header value? Do I have to receive chunks and stitch them together to one long string?

One more thing -> how long is the max. header value I can receive?

Many thanks for your help .

Hi,

I solved the problem by editing

Code: [Select all] [Expand/Collapse]

1. CONFIG_HTTPD_MAX_REQ_HDR_LEN
