在Ajax中定义用于生成zip PHP的标头

一旦ajax调用就绪，您可以使用location.href重定向到生成的zip文件（这意味着您的zip文件也就绪） 从PHP返回zip文件的url，然后使用下面的
function zipExtract(candidacy)
{
var content = {};
content['candidacy'] = candidacy;
$.post('zipCandidacy.php', content, function(data)
{
location.href=data;
});
}
我认为你不需要下面的内容，但写下来只是为了以防万一 请记住，在ajax中不设置头。您可以使用header（）函数在php文件中设置头 zip的mime类型（如果服务器无法满足您的zip请求，请下载）
application/zip、application/octet流// We'll be outputting a ZIP
header('Content-Type: application/zip, application/octet-stream');
// It will be called myzip.zip
header('Content-Disposition: attachment; filename="myzip.zip"');
// your PHP code and FPDF stuff
我终于找到了解决办法！正如您向我指出的那样，Oliver，AJAX并不是我想要的定义标题的最佳方式。因此，在执行onclick事件时，我重定向到php处理页面，以便继续下载zip文件

谢谢你的回答@Oliver！问题是我在js中的函数与onclick事件相关。我有一份候选名单，我建议用zip格式下载候选名单的内容。在这个onclick事件中，我检索已单击候选资格的id。这就是我使用ajaxIf的原因。如果我理解得很好，我在PHP中添加了“return$zip_name”，然后，我修改了我的ajax，这是正确的？？嘿，是的，这是正确的，确保你用唯一的代码命名你的zip文件，就像有超过一个人使用你的应用程序/网站一样，你最终会被覆盖文件。祝你好运如果您需要帮助，请询问更多：）嗯，我编辑了我的脚本，并尝试了它，问题是所有内容从现在起都在url中。zip下载的标题没有显示@OliverI尝试了另一种方式，但仍然没有显示：/function zipExtract（candidate）{var content={}；content['candidate']=candidate；$.ajax（{type:“POST”，url:“zipCandidacy.php”，contentType:“application/zip”，数据：内容，成功：函数（data）{$（'#zipContent'）.html（data）；}，}）}}您不能使用AJAX直接将文件下载到磁盘。响应将始终返回到JavaScript，而不是用户的设备。您必须使用常规回发（如果需要，您可以使用JS伪造表单提交），或者将zip保存到服务器，然后让AJAX返回一个URL，然后您可以使用JavaScript将浏览器导航到该URL。这些都是您的选项。完美！location.href部分必须放在前端，尽管它可能可以正常工作。祝您好运，坚持并享受：）啊哈谢谢你的支持@Oliver！：）如果你看到实现我愿望的另一种方式，请毫不犹豫地提出！
