Alfresco 更新文件 - 错误 POST [英] Alfresco Update File - ERROR POST
问题描述
我正在尝试更新 Alfresco 中的文件...我编写了以下代码:
I'm trying to update a file in Alfresco... And I make this code:
var csrf_header = Alfresco.util.CSRFPolicy.getHeader();
var csrf_token = Alfresco.util.CSRFPolicy.getToken();
function getResponse(pdfbase64) {
var fd = new FormData();
if (Alfresco.util.CSRFPolicy && Alfresco.util.CSRFPolicy.isFilterEnabled())
{
fd.append(csrf_header, csrf_token);
}
fd.append("username", "admin");
fd.append("updatenoderef", nodeRef);
fd.append("filedata", pdfbase64);
fd.append("majorversion", "true");
fd.append("overwrite", "true");
alert(fileUpdateURL);
$.ajax({
url: fileUpdateURL,
type: "POST",
data: fd,
processData: false, // tell jQuery not to process the data
contentType: false // tell jQuery not to set contentType
});
}
变量 pdfbase64 是放在文件上的内容(我对文件所做的更改以更新 base64 中的文件)，但也许这不是正确的格式?，nodeRef 是文件的引用，如:"workspace://SpacesStore/4fb1b7e7-2502-4011-8870-17e8d626b93b" 和 fileUpdateURL 是URL to POST: http://localhost:8080/share/proxy/alfresco/api/upload
The variable pdfbase64 is the content to put on the file (the changes that I made on the file to update the file in base64), but maybe this isn't the right format?, nodeRef is the reference of the file like: "workspace://SpacesStore/4fb1b7e7-2502-4011-8870-17e8d626b93b" and fileUpdateURL is the URL to POST: http://localhost:8080/share/proxy/alfresco/api/upload
我收到错误:

如果我使用
http://localhost:8080/alfresco/service/api/upload
代替
http://localhost:8080/share/proxy/alfresco/api/upload
我收到错误:
{
"status" :
{
"code" : 400,
"name" : "Bad Request",
"description" : "Request sent by the client was syntactically incorrect."
},
"message" : "Required parameters are missing",
"exception" : "",
"callstack" :
[
],
"server" : "Community v5.0.0 (d r99759-b2) schema 8,022",
"time" : "Jan 24, 2016 1:14:41 PM"
}
有人可以帮我吗?
我尝试使用 http://localhost:8080/share/proxy 发出请求/alfresco/api/upload 用这个:
I try to make the request with http://localhost:8080/share/proxy/alfresco/api/upload with this:
function getResponse(pdfbase64) {
var csrf_header = Alfresco.util.CSRFPolicy.getHeader();
var csrf_token = Alfresco.util.CSRFPolicy.getToken();
var fd = new FormData();
if (Alfresco.util.CSRFPolicy && Alfresco.util.CSRFPolicy.isFilterEnabled())
{
fd.append(csrf_header, csrf_token);
fileUpdateURL += "?" + Alfresco.util.CSRFPolicy.getParameter() + "=" + encodeURIComponent(Alfresco.util.CSRFPolicy.getToken());
}
fd.append("username", "admin");
fd.append("updatenoderef", nodeRef);
fd.append("filedata", pdfbase64);
fd.append("majorversion", "true");
fd.append("overwrite", "true");
alert(fileUpdateURL);
$.ajax({
url: fileUpdateURL,
type: "POST",
data: fd,
processData: false, // tell jQuery not to process the data
contentType: false // tell jQuery not to set contentType
});
}
但是我得到了错误:
{
"status" :
{
"code" : 400,
"name" : "Bad Request",
"description" : "Request sent by the client was syntactically incorrect."
},
"message" : "Required parameters are missing",
"exception" : "",
"callstack" :
[
],
"server" : "Community v5.0.0 (d r99759-b2) schema 8,022",
"time" : "Jan 24, 2016 1:14:41 PM"
}
推荐答案
尝试在函数中移动这些行:
Try moving these lines inside your function:
var csrf_header = Alfresco.util.CSRFPolicy.getHeader();
var csrf_token = Alfresco.util.CSRFPolicy.getToken();
如果这不能解决您的问题并且问题不是 csrf_* 变量的变量范围问题，那么您应该尝试 这里
And if that does not solve your problem and the issue turn out to be not a matter of variable scope for csrf_* vars, then you should try hint (2) from here
更新:正如我在我们的聊天中所解释的，您应该替换 :
UPDATE : As I explained in our chat you should replace :
fd.append("filedata", pdfbase64);
与:
fd.append("filedata", new Blob([pdfbase64], {type: 'application/pdf'}););
