Chapter 2. API Reference
esp_err_t esp_http_client_flush_response(esp_http_client_handle_t client, int *len)
Process all remaining response data This uses an internal buffer to repeatedly receive, parse, and discard re-
sponse data until complete data is processed. As no additional user-supplied buffer is required, this may be
preferrable to esp_http_client_read_response in situations where the content of the response may
be ignored.
Return
• ESP_OK If successful, len will have discarded length
• ESP_FAIL If failed to read response
• ESP_ERR_INVALID_ARG If the client is NULL
Parameters
• [in] client: The esp_http_client handle
• len: Length of data discarded
esp_err_t esp_http_client_get_url(esp_http_client_handle_t client, char *url, const int len)

• ESP_FAIL
Parameters

esp_err_t esp_http_client_get_chunk_length(esp_http_client_handle_t client, int *len)

Return

• ESP_FAIL If the server is not a chunked server
