從PhantomJS內部發送時，不傳輸HTTP Content-type標頭和正文

[英]HTTP Content-type header and body are not transmitted when sent from within PhantomJS

 原文  2014-11-13 16:20:33  9   1    http/ phantomjs/ content-type/ http-delete

問題描述

使用內容類型標頭和正文啟動HTTP DELETE請求時，這兩個元素是：

  • 從Chrome內發起請求后，收到好評，
  • 從PhantomJS內部發起請求時未收到。

按照標准，這兩個行為中的哪個？

要注意的是，在兩種情況下，客戶端和服務器都是相同的。

以下是服務器級別的請求日志。

HTTP / 1.1的RFC 2616在9.7章中指定了DELETE方法。 它沒有指定有關封裝的實體 （消息體），其中它對於POST和PUT說明文字東西。

從您的日志中可以明顯看出，PhantomJS甚至不發送消息正文，因此不需要包括內容類型，因為它假定由於未定義它永遠不會被使用。 Chrome似乎會發送郵件正文。

有一份更新草案，其中包括第6.7章中的以下文本：

DELETE請求上的實體沒有定義的語義。 請注意，在DELETE請求上發送正文可能會導致某些現有實現拒絕該請求。

由於PhantomJS 1.x基於三年以上的WebKit版本（預草稿），因此它的行為是這樣的。 另一方面，Chrome可能已實現了建議的草案，並根據DELETE請求主動發送了正文。 有關更多信息，請參見此問題 。

如果您的操作取決於DELETE方法的消息正文，則應更改實現，以便要刪除的資源完全由URI定義。

相關問題 將響應標頭“ Content-Type”設置為“ application / json”時，HTTP響應正文可以為空嗎？ 當內容類型沒有在http中發送時會出現什么問題？ 當郵件正文為空時，是否應出現Content-Type標頭？ 是否始終需要Content-Type HTTP標頭？ HTTP 內容類型標頭和 JSON JSONP 響應 http 內容類型 header Content-Type HTTP標頭中“charset”的范圍 angularjs $ http強制內容類型頭 Python 請求不發送 {"Content-Type":"application/json"} 標頭或只是忽略 HTTP POST 中的正文 使用Rack :: Static，不發送Content-Type標頭
