Hi Jonathan! You have two options here: 1) you can increase the client buffers According to the documentation: http://nginx.org/en/docs/njs/reference.html#http <http://nginx.org/en/docs/njs/reference.html#http> r.requestBody returns the client request body if it has not been written to a temporary file. To ensure that the client request body is in memory, its size should be limited by client_max_body_size, and a sufficient buffer size should be set using client_body_buffer_size. 2) you can open the file with the client’s request using request_body_file variable (http://nginx.org/en/docs/http/ngx_http_core_module.html#var_request_body_file) var fs = require(‘fs’); var large_body = fs.readFileSync(r.variables.request_body_file) > > _______________________________________________ > nginx mailing list > nginx@nginx.org > http://mailman.nginx.org/mailman/listinfo/nginx
