[英]Making an HTTP POST call with multipart/form-data using jQuery?
I'm trying to make a HTTP POST call with multipart/form-data , using jQuery: 我正在尝试使用jQuery使用multipart / form-data进行HTTP POST调用:
$.ajax({
url: 'http://localhost:8080/dcs/rest',
type: 'POST',
contentType:'multipart/form-data',
data: 'dcs.source=boss-web&query=data&dcs.algorithm=lingo&dcs.output.format=JSON&dcs.clusters.only=true',
//dataType: "jsonP",
success: function(jsonData) {alert('POST alert'); data=jsonData ; },
error : function(XMLHttpRequest, textStatus, errorThrown) {
console.log('An Ajax error was thrown.');
console.log(XMLHttpRequest);
console.log(textStatus);
console.log(errorThrown);
}
});
It doesn't work. 它不起作用。 Firebug returns an undefined error and the returned
XMLHttpRequst
object multipart field is set to false. Firebug返回未定义的错误,返回的
XMLHttpRequst
对象multipart字段设置为false。
What can i do to make this work with jQuery? 我可以做些什么来使用jQuery工作? And if it's not possible is there a simple to achieve this?
如果不可能有一个简单的实现这个?
ie idon't need to transfer files , just some data. 即idon't不需要传输文件,只需要一些数据。 but the server requires multipart.
但服务器需要multipart。
multipart/form-data
doesn't look at like this: multipart/form-data
看起来不像这样:
dcs.source=boss-web&query=data&dcs.algorithm=lingo&dcs.output.format=JSON&dcs.clusters.only=true
This is application/x-www-form-urlencoded
. 这是
application/x-www-form-urlencoded
。
Here's an example of how multipart/form-data
request looks like. 以下是
multipart/form-data
请求的示例 。 And the related RFC 1867 . 和相关的RFC 1867 。
multipart/form-data
is quite often associated with uploading files. multipart/form-data
经常与上传文件相关联。 If this is your case you could take a look at the jquery form plugin which allows you to ajaxify forms and supports file uploads as well. 如果是这种情况,您可以查看jquery表单插件 ,它允许您ajaxify表单并支持文件上传 。
This way works: 这种方式有效:
$( "form#upload-form" )
.attr( "enctype", "multipart/form-data" )
.attr( "encoding", "multipart/form-data" );
$.ajax({
type: "POST",
contentType:attr( "enctype", "multipart/form-data" ),
url: "/adm/oferta_insert",
data: dados,
success: function( data ) {
alert( data );
}
});
