[英]GWT FileUpload - Set the response Content-Type through Client code
I have a file upload form in GWT and the upload process works fine.我在 GWT 中有一个文件上传表单,上传过程正常。 Though, I have problem getting the response.但是,我在获得响应时遇到了问题。 The response capturing code is:响应捕获代码为:
formUpload.addSubmitCompleteHandler(new FormPanel.SubmitCompleteHandler() {
@Override
public void onSubmitComplete(final SubmitCompleteEvent event) {
fileUploadControl.handleResponse(htmlToText(event.getResults()));
}
});
The event.getResults()
always results in null
. event.getResults()
总是导致null
。 Upon investigating, I found that the response Content-Type
should be one of text/html
or text/plain
.经过调查,我发现响应Content-Type
应该是text/html
或text/plain
。 In my case, it is application/xml
and I can't control the server response as well.就我而言,它是application/xml
,我也无法控制服务器响应。
I was wondering if it is possible to set Accept
request header in file upload form.我想知道是否可以在文件上传表单中设置Accept
请求标头。 If it is not possible, any other suggestion is appreciated.如果这是不可能的,任何其他建议表示赞赏。
See documentation SubmitCompleteEvent#getResults请参阅文档SubmitCompleteEvent#getResults
public java.lang.String getResults()
Gets the result text of the form submission.public java.lang.String getResults()
获取表单提交的结果文本。
Returns:返回:
the result html, or null if there was an error reading it结果 html,如果读取时出错,则为 null
Tip:小费:
The result html can be null as a result of submitting a form to a different domain.由于将表单提交到不同的域,结果 html 可能为 null。
If It is working without errors, maybe domains are different.如果它正常工作,则域可能不同。
