php - Can servers block curl requests specifically? -


generally speaking, possible server block php curl request?

i've been making curl requests every 15 minutes public-facing url 6-8 months. other day stopped working, , url started returning empty string.

when hit url in browser or python request, returns expected data.

i decided try hitting same url file_get_contents() function in php, , works expected well.

since found bandaid solution now, there difference between default headers curl sends vs file_get_contents() allow 1 request blocked , other through?

generally speaking, possible server block php curl request?

sort of. server can block requests if user agent string looks comes curl. try using -a option set custom user agent string.

curl -a "foo/1.1" <url>

edit: oops see said "from php", set curlopt_useragent option:

curl_setopt($curl, curlopt_useragent, 'foo/1.1');

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
