我遇到了一个问题。我正在用AJAX构建某种幻灯片编辑器。我有一个PHP脚本，其中有许多功能，可以选择不同的GET参数。一切正常。但是当我试图发布幻灯片并保存它们时，一个名为transformorigin的值从50% 50% 0变为50500。
slide.php ? action = get& id = 1
[{"slideid":1,"position":1,"background":{"id":"3","name":"http:'/'/test.com'/uploads'/1'/img'/20140729_174513.jpg"},"delay":4000,"timeshift":0,"active":true,"transition2d":[2,7,9],"transition3d":[],"layers":[{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":80,"offsety":0,"duration":1000,"delay":0,"fade":true,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"50% 50% 0","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":-80,"offsety":0,"duration":400,"delay":0,"fade":true,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"50% 50% 0","easing":{"id":14,"name":"easeInOutQuint"}}},{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":80,"offsety":0,"duration":1000,"delay":0,"fade":true,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"50% 50% 0","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":-80,"offsety":0,"duration":400,"delay":0,"fade":true,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"50% 50% 0","easing":{"id":14,"name":"easeInOutQuint"}}}]},{"slideid":2,"position":2,"background":{"id":"4","name":"http:'/'/test.com'/uploads'/1'/img'/20140729_174608.jpg"},"delay":4000,"timeshift":0,"active":true,"transition2d":[2,7,9],"transition3d":[],"layers":[]}]
POST slide.php ? action = post& id = 1
[{"slideid":1,"position":1,"background":{"id":"3","name":"http:'/'/test.com'/uploads'/1'/img'/20140729_174513.jpg"},"delay":4000,"timeshift":0,"active":true,"transition2d":[2,7,9],"transition3d":[],"layers":[{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":80,"offsety":0,"duration":1000,"delay":0,"fade":true,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"50500","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":80,"offsety":0,"duration":400,"delay":0,"fade":true,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"50500","easing":{"id":14,"name":"easeInOutQuint"}}},{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":80,"offsety":0,"duration":1000,"delay":0,"fade":true,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"50500","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":80,"offsety":0,"duration":400,"delay":0,"fade":true,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"50500","easing":{"id":14,"name":"easeInOutQuint"}}}]},{"slideid":2,"position":2,"background":{"id":"4","name":"http:'/'/test.com'/uploads'/1'/img'/20140729_174608.jpg"},"delay":4000,"timeshift":0,"active":true,"transition2d":[2,7,9],"transition3d":[],"layers":[]}]
我不明白为什么transformorigin在POST之后改变了。当我点击发布请求的firebug post选项卡时，它仍然是50% 50% 0。服务器端输入
会得到50500echo file_get_contents('php://input');
开头
这是我的Javascript/jQuery:function saveSlides(success,error) {
$.ajax({
url: '/slide.php?action=post&id=' + lid,
type: 'POST',
dataType: 'json',
data: JSON.stringify(slides),
contentType: "application/json; charset=UTF-8",
success: function(data) {
if ("undefined" == typeof(data.error)) {
slides = data;
if (isFunction(success))
success(data);
} else {
if (isFunction(error))
error(data);
}
},error: function() {
if (isFunction(error))
error({"error":{"id":100,"message":"Could not retrieve data."}});
}
});
}
即使我指定了contentType它也不会改变内容类型
提前谢谢你
更新1:用JavaScript编码所有内容后，这是我发送给php脚本的内容:
[{"slideid":"1","position":"1","background":{"id":"3","name":"http%3A//test.com/uploads/1/img/20140729_174513.jpg"},"delay":"4000","timeshift":"0","active":"true","transition2d":[2,7,9],"transition3d":[],"layers":[{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":"80","offsety":"0","duration":"1000","delay":"0","fade":"true","rotate":"0","rotatex":"0","rotatey":"0","skewx":"0","skewy":"0","scalex":"1","scaley":"1","transformorigin":"50%25%2050%25%200","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":"-80","offsety":"0","duration":"400","delay":"0","fade":"true","rotate":"0","rotatex":"0","rotatey":"0","skewx":"0","skewy":"0","scalex":"1","scaley":"1","transformorigin":"50%25%2050%25%200","easing":{"id":14,"name":"easeInOutQuint"}}},{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":"80","offsety":"0","duration":"1000","delay":"0","fade":"true","rotate":"0","rotatex":"0","rotatey":"0","skewx":"0","skewy":"0","scalex":"1","scaley":"1","transformorigin":"50%25%2050%25%200","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":"-80","offsety":"0","duration":"400","delay":"0","fade":"true","rotate":"0","rotatex":"0","rotatey":"0","skewx":"0","skewy":"0","scalex":"1","scaley":"1","transformorigin":"50%25%2050%25%200","easing":{"id":14,"name":"easeInOutQuint"}}}]},{"slideid":"2","position":"2","background":{"id":"4","name":"http%3A//test.com/uploads/1/img/20140729_174608.jpg"},"delay":"4000","timeshift":"0","active":"true","transition2d":[2,7,9],"transition3d":[],"layers":[]}]
这是我从php脚本中得到的结果:
[{"slideid":1,"position":1,"background":{"id":"3","name":"http:'/'/test.com'/uploads'/1'/img'/20140729_174513.jpg"},"delay":4000,"timeshift":0,"active":false,"transition2d":[2,7,9],"transition3d":[],"layers":[{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":80,"offsety":0,"duration":1000,"delay":0,"fade":false,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"5025205025200","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":80,"offsety":0,"duration":400,"delay":0,"fade":false,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"5025205025200","easing":{"id":14,"name":"easeInOutQuint"}}},{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":80,"offsety":0,"duration":1000,"delay":0,"fade":false,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"5025205025200","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":80,"offsety":0,"duration":400,"delay":0,"fade":false,"rotate":0,"rotatex":0,"rotatey":0,"skewx":0,"skewy":0,"scalex":1,"scaley":1,"transformorigin":"5025205025200","easing":{"id":14,"name":"easeInOutQuint"}}}]},{"slideid":2,"position":2,"background":{"id":"4","name":"http:'/'/test.com'/uploads'/1'/img'/20140729_174608.jpg"},"delay":4000,"timeshift":0,"active":false,"transition2d":[2,7,9],"transition3d":[],"layers":[]}]
所以现在它从50%25%2050%25%200变成了5025205025200。
在我添加一个url解码到我的php脚本后，它再次返回50500。
更新2:现在我正在尝试测试php文件。
当我这样做时:
echo file_get_contents('php://input');
die;
我收到的和我发送的是一样的
[{"slideid":"1","position":"1","background":{"id":"3","name":"http%3A//test.com/uploads/1/img/20140729_174513.jpg"},"delay":"4000","timeshift":"0","active":"true","transition2d":[2,7,9],"transition3d":[],"layers":[{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":"80","offsety":"0","duration":"1000","delay":"0","fade":"true","rotate":"0","rotatex":"0","rotatey":"0","skewx":"0","skewy":"0","scalex":"1","scaley":"1","transformorigin":"50%25%2050%25%200","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":"-80","offsety":"0","duration":"400","delay":"0","fade":"true","rotate":"0","rotatex":"0","rotatey":"0","skewx":"0","skewy":"0","scalex":"1","scaley":"1","transformorigin":"50%25%2050%25%200","easing":{"id":14,"name":"easeInOutQuint"}}},{"background":[],"tag":"h1","content":"Test","style":{"top":"0px","left":"0px"},"transitionin":{"offsetx":"80","offsety":"0","duration":"1000","delay":"0","fade":"true","rotate":"0","rotatex":"0","rotatey":"0","skewx":"0","skewy":"0","scalex":"1","scaley":"1","transformorigin":"50%25%2050%25%200","easing":{"id":14,"name":"easeInOutQuint"}},"transitionout":{"offsetx":"-80","offsety":"0","duration":"400","delay":"0","fade":"true","rotate":"0","rotatex":"0","rotatey":"0","skewx":"0","skewy":"0","scalex":"1","scaley":"1","transformorigin":"50%25%2050%25%200","easing":{"id":14,"name":"easeInOutQuint"}}}]},{"slideid":"2","position":"2","background":{"id":"4","name":"http%3A//test.com/uploads/1/img/20140729_174608.jpg"},"delay":"4000","timeshift":"0","active":"true","transition2d":[2,7,9],"transition3d":[],"layers":[]}]
当我这样做的时候:
$slides = json_decode(file_get_contents('php://input'),true);
print_r($slides);
die;
我得到这个:

所以现在我必须解码它
更新3:我必须使用encodeURIComponent()在javascript和urldecode()在php。
非常感谢，现在它可以工作了
您的文本被解释为字符编码，因为它前面有一个%符号。参见这个stackoverflow问题。你能在它被处理之前逃离它吗?
您可以在对对象进行字符串化后对文本进行编码，然后在它到达您时对其进行解码。
