When you make a POST request, you have to encode the data that forms the body of the request in some way. HTML forms provide three methods of encoding. application/x-www-form-urlencoded (the default) multipart/form-data text/plain Work was being done on adding application/json, but that has been abandoned. (Other encodings are possible with HTTP requests generated using other … [Read more...]

What you have should work. If, however, the spaces provided are defaulting to... something else? You can use the whitespace regex: str = "Hello I'm your String"; String[] splited = str.split("\s+"); This will cause any number of consecutive spaces to split your string into tokens. As a side note, I'm not sure "splited" is a word :) I believe the state of being the victim of a … [Read more...]

There is an ordered set (possible new link) recipe for this which is referred to from the Python 2 Documentation. This runs on Py2.6 or later and 3.0 or later without any modifications. The interface is almost exactly the same as a normal set, except that initialisation should be done with a list. OrderedSet([1, 2, 3]) This is a MutableSet, so the signature for .union doesn't … [Read more...]

You are mixing implicit joins with explicit joins. That is allowed, but you need to be aware of how to do that properly. The thing is, explicit joins (the ones that are implemented using the JOIN keyword) take precedence over implicit ones (the 'comma' joins, where the join condition is specified in the WHERE clause). Here's an outline of your query: SELECT … FROM a, b LEFT … [Read more...]

YES!! There is a way to detach a busy device immediately - even if it is busy and cannot be unmounted forcefully. You may cleanup all later: umount -l /PATH/OF/BUSY-DEVICE umount -f /PATH/OF/BUSY-NFS (NETWORK-FILE-SYSTEM) NOTE/CAUTION These commands can disrupt a running process, cause data loss OR corrupt open files. Programs accessing target DEVICE/NFS files may throw … [Read more...]

This is entirely implementation specific, but it appears that in the C++ environment you're working in, RAND_MAX is equal to INT_MAX. Because of this, RAND_MAX + 1 exhibits undefined (overflow) behavior, and becomes INT_MIN. While your initial statement was dividing (random # between 0 and INT_MAX)/(INT_MAX) and generating a value 0 >32)}; rng.seed(ss); // initialize a … [Read more...]

LinkedList[] vertex = new LinkedList[5]; int i = 0, m = 6; while(i!=m){ int temp = sc.nextInt(); int temp2 = sc.nextInt(); // Make sure the list is initialized before adding to it if (vertex[temp] == null) { vertex[temp] = new LinkedList(); } vertex[temp].add(temp2); i++; } //initialize array LinkedList[] vertex = new LinkedList[5]; //initialize array … [Read more...]

Use std::string::find as follows: if (s1.find(s2) != std::string::npos) { std::cout … [Read more...]

TL;DR Summary; if you have binary (non-alphanumeric) data (or a significantly sized payload) to transmit, use multipart/form-data. Otherwise, use application/x-www-form-urlencoded. The MIME types you mention are the two Content-Type headers for HTTP POST requests that user-agents (browsers) must support. The purpose of both of those types of requests is to send a list of … [Read more...]

Try this in the console: JSON.parse(undefined) Here is what you will get: Uncaught SyntaxError: Unexpected token u in JSON at position 0 at JSON.parse () at :1:6 In other words, your app is attempting to parse undefined, which is not valid JSON. There are two common causes for this. The first is that you may be referencing a non-existent property (or even a … [Read more...]
