我嘗試從瀏覽器訪問我開發的簡單郵件列表服務。我修改了一個我發現的工作示例,但我不知道爲什麼請求似乎無法到達該服務,因此沒有響應返回。用SOAP信封調用Web服務使用Javascript失敗
使用SOAP信封是一個需求,我需要知道這段代碼可能有什麼問題,而不是如何使用其他技術做同樣的事情。 (該服務在GlassFish服務器上正確部署,並且我有一個正在工作的Java客戶端來測試它,所以服務沒有問題)
有人看到壞東西(我也加入了WSDL,如果你需要的話其他細節不要猶豫)?謝謝!

Pure Javascript w/no frameworks? AJAX是一種痛苦... – hugomg
是純粹的Javascript。我發現了一個效果很好的例子,唯一的區別是它發出'POST'請求。 – talnicolas
