<p>使用PHP curl获取页面内容或提交数据，有时候希望返回的内容作为变量储存，而不是直接输出。一般curl爬取过程中，会返回一个http_code，通过这个状态我们就可以知道请求的结果，今天测试curl爬取远程图片的时候出现状态码为400的错误，报错内容为”invalid User-Agent header“<span style="color: rgb(51, 51, 51); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 14px; background-color: rgb(255, 255, 255);">①</span>，后来就找了一些有关”http_code状态码“的资料，给大家参考下：</p><p>下面是他们的意义信息<br/></p><p>$http_code[&quot;0&quot;]&nbsp; &nbsp; = &quot;Unable to access&quot;;</p><p>$http_code[&quot;100&quot;] = &quot;Continue&quot;;</p><p>$http_code[&quot;101&quot;] = &quot;Switching Protocols&quot;;</p><p>$http_code[&quot;200&quot;] = &quot;OK&quot;;</p><p>$http_code[&quot;201&quot;] = &quot;Created&quot;;</p><p>$http_code[&quot;202&quot;] = &quot;Accepted&quot;;</p><p>$http_code[&quot;203&quot;] = &quot;Non-Authoritative Information&quot;;</p><p>$http_code[&quot;204&quot;] = &quot;No Content&quot;;</p><p>$http_code[&quot;205&quot;] = &quot;Reset Content&quot;;</p><p>$http_code[&quot;206&quot;] = &quot;Partial Content&quot;;</p><p>$http_code[&quot;300&quot;] = &quot;Multiple Choices&quot;;</p><p>$http_code[&quot;301&quot;] = &quot;Moved Permanently&quot;;</p><p>$http_code[&quot;302&quot;] = &quot;Found&quot;;</p><p>$http_code[&quot;303&quot;] = &quot;See Other&quot;;</p><p>$http_code[&quot;304&quot;] = &quot;Not Modified&quot;;</p><p>$http_code[&quot;305&quot;] = &quot;Use Proxy&quot;;</p><p>$http_code[&quot;306&quot;] = &quot;(Unused)&quot;;</p><p>$http_code[&quot;307&quot;] = &quot;Temporary Redirect&quot;;</p><p>$http_code[&quot;400&quot;] = &quot;Bad Request&quot;;</p><p>$http_code[&quot;401&quot;] = &quot;Unauthorized&quot;;</p><p>$http_code[&quot;402&quot;] = &quot;Payment Required&quot;;</p><p>$http_code[&quot;403&quot;] = &quot;Forbidden&quot;;</p><p>$http_code[&quot;404&quot;] = &quot;Not Found&quot;;</p><p>$http_code[&quot;405&quot;] = &quot;Method Not Allowed&quot;;</p><p>$http_code[&quot;406&quot;] = &quot;Not Acceptable&quot;;</p><p>$http_code[&quot;407&quot;] = &quot;Proxy Authentication Required&quot;;</p><p>$http_code[&quot;408&quot;] = &quot;Request Timeout&quot;;</p><p>$http_code[&quot;409&quot;] = &quot;Conflict&quot;;</p><p>$http_code[&quot;410&quot;] = &quot;Gone&quot;;</p><p>$http_code[&quot;411&quot;] = &quot;Length Required&quot;;</p><p>$http_code[&quot;412&quot;] = &quot;Precondition Failed&quot;;</p><p>$http_code[&quot;413&quot;] = &quot;Request Entity Too Large&quot;;</p><p>$http_code[&quot;414&quot;] = &quot;Request-URI Too Long&quot;;</p><p>$http_code[&quot;415&quot;] = &quot;Unsupported Media Type&quot;;</p><p>$http_code[&quot;416&quot;] = &quot;Requested Range Not Satisfiable&quot;;</p><p>$http_code[&quot;417&quot;] = &quot;Expectation Failed&quot;;</p><p>$http_code[&quot;500&quot;] = &quot;Internal Server Error&quot;;</p><p>$http_code[&quot;501&quot;] = &quot;Not Implemented&quot;;</p><p>$http_code[&quot;502&quot;] = &quot;Bad Gateway&quot;;</p><p>$http_code[&quot;503&quot;] = &quot;Service Unavailable&quot;;</p><p>$http_code[&quot;504&quot;] = &quot;Gateway Timeout&quot;;</p><p>$http_code[&quot;505&quot;] = &quot;HTTP Version Not Supported&quot;;</p><p><span style="font-size: 14px;"><span style="color: rgb(51, 51, 51); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; background-color: rgb(255, 255, 255);">①出现报错的“invalid User-Agent header”相关解决办法可参考《</span><a href="https://panxu.net/article/8389.html" target="_blank">php curl抓取远程图片报错：&quot;invalid User-Agent header&quot;解决办法</a>》一文。</span></p><p>好了，以上就是“php curl请求中http_code状态码详解”的全部内容了，希望本文的内容对大家的学习或者工作具有一定的参考学习价值，如果有疑问大家可以留言交流。</p>
