 referArgs['#userID\#'] = userId;
 referArgs['\#userName\#'] = userName;
 return referArgs;
}
/* 替换URL的参数 */
var replaceUrlParams = function(url){
 var actualUrl = "";
 var referArgs = setReferArgs();
 for(var key in referArgs){
 var e = eval('/'+ key +'/g'); 
 actualUrl = url.replace(e,referArgs[key]);
 url = actualUrl;
 }
 return actualUrl;
}
Copy after login

栗子:

“http://10.0.0.250:8088/test?uesrID=#userID#” 替换成对应数值 “http://10.0.0.250:8088/test?uesrID=12345”;

“http://10.0.0.250:8088/test/#userID#” 替换成对应数值 “http://10.0.0.250:8088/12345”;

延伸:

js使用正则表达式从url中获取参数值


//从url中获取参数值
 function getvl(name) {
 var reg = new RegExp("(^|\\?|&)"+ name +"=([^&]*)(\\s|&|$)", "i");
 if (reg.test(location.href)) return unescape(RegExp.$2.replace(/\+/g, " "));
 return "";
 };
 var code = getvl("code");
Copy after login

C++ function parameter type safety check C++ function parameter type safety check Apr 19, 2024 pm 12:00 PM

C++ parameter type safety checking ensures that functions only accept values ​​of expected types through compile-time checks, run-time checks, and static assertions, preventing unexpected behavior and program crashes: Compile-time type checking: The compiler checks type compatibility. Runtime type checking: Use dynamic_cast to check type compatibility, and throw an exception if there is no match. Static assertion: Assert type conditions at compile time.

Arena's latest battle report has sparked heated debate, Karpathy: This is the only list I trust Apr 10, 2024 pm 03:16 PM

An open source model that can beat GPT-4 has appeared! The latest battle report of the large model arena: the 104 billion parameter open source model CommandR+ climbed to 6th place, tying with GPT-4-0314 and surpassing GPT-4-0613. Image This is also the first open-weight model to beat GPT-4 in the large model arena. The large model arena is one of the only test benchmarks that the master Karpathy trusts. Image CommandR+ from AI unicorn Cohere. The co-founder and CEO of this large model startup is none other than Aidan Gomez, the youngest author of Transformer (referred to as the wheat harvester). As soon as this battle report came out, another wave of big model clubs started

Advanced usage of reference parameters and pointer parameters in C++ functions Advanced usage of reference parameters and pointer parameters in C++ functions Apr 21, 2024 am 09:39 AM

Reference parameters in C++ functions (essentially variable aliases, modifying the reference modifies the original variable) and pointer parameters (storing the memory address of the original variable, modifying the variable by dereferencing the pointer) have different usages when passing and modifying variables. Reference parameters are often used to modify original variables (especially large structures) to avoid copy overhead when passed to constructors or assignment operators. Pointer parameters are used to flexibly point to memory locations, implement dynamic data structures, or pass null pointers to represent optional parameters.
