HTTP状态码对于浏览器显示内容有影响么?

Jun 23, 2016 pm 02:20 PM

比如说服务器在发送响应的时候使用了一个未定义的状态码和状态消息,浏览器会出现什么特别的行为么?

你可以试试啊,写一个语句又不是很难

浏览器一般都能容错的,反正我没试过这样做

你可以写试一试。。。。

我试过了,没发现什么问题。除了在Chrome的审查元素的Network标签里看的时候返回的文件的颜色不一样。
但是现在没问题不代表一直不会有问题吧?我想知道的是将来会不会有问题。

易入难出,这是写代码的原则,输出要容错,但输出一定要符合规格

易入难出,这是写代码的原则,输出要容错,但输出一定要符合规格 扩展服务器响应文件的头有什么标准么?我想向浏览器发送一些文本,但是这些文本不能存在于响应文件的正文中,只能放在头里。但是不知道AJAX能不能获取全部的头。

查rfc2616 http 1.1标准

查rfc2616 http 1.1标准 有没有什么样的Response Header Fields的名字是绝对不会被标准所采用的?我刚才用了一个20多个字符的名字,但是还是感觉不放心。刚才查了一下,AJAX有这个方法:getResponseHeader(header),提取Header相当方便。

干嘛不用cookie?cookie就写在header的,不在正文

4.7.3 The getResponseHeader() method

client . getResponseHeader(header)
Returns the header field value from the response of which the field name matches header, unless the field name is Set-Cookie or Set-Cookie2.

服务器传递给浏览器之后还要用js读取cookie,感觉有点麻烦。而且我做的这个东西可能会有很多AJAX请求异步执行,不知道使用cookie会不会乱套。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.
