ajaxchromephp

我使用php+ajax学习进行网站建设，当使用 xmlHttp.setRequestHeader("content-length",Querystring.length); 时，在chorme里出现了这个错误，在webkit的浏览器里都会出现这个问题，请问如何解决呢？它提示，这是不安全吗。那么该如何改呢？

回复内容：

是的，实际上chrome是按照w3c标准来执行的，你可以看这里的原文描述，http://www.w3.org/TR/XMLHttpRequest/#...

我把它摘录出来

Terminate these steps if header is a case-insensitive match for one of the following headers:

Accept-Charset
Accept-Encoding
Connection
Content-Length
Cookie
Cookie2
Content-Transfer-Encoding
Date
Expect
Host
Keep-Alive
Referer
TE
Trailer
Transfer-Encoding
Upgrade
User-Agent
Via

也就是说，当你的header匹配以上字符时，这一步骤将被终止

Best Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

Best PHP Performance Optimization TechniquesMay 07, 2025 pm 03:05 PM

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
