javascript - Alfresco 更新文件 - 错误发布

Question

我正在尝试更新 Alfresco 中的文件...我编写了以下代码:

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 是要放在文件中的内容(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，例如:"workspace://SpacesStore/4fb1b7e7-2502-4011-8870-17e8d626b93b" 和 fileUpdateURL 是URL 到 POST:http://localhost:8080/share/proxy/alfresco/api/upload

Source of params

我得到了错误:

编辑: 如果我使用

http://localhost:8080/alfresco/service/api/upload

代替

http://localhost:8080/share/proxy/alfresco/api/upload

我得到错误:

{
    "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"
}

谁能帮帮我？

编辑2:

我尝试使用 http://localhost:8080/share/proxy/alfresco/api/upload 发出请求有了这个:

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"
    }

Answer 1

尝试在您的函数中移动这些行:

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，并且问题证明不是 csrf_* 变量的变量范围问题，那么您应该尝试 here 中的提示 (2)

更新: 正如我在聊天中解释的那样，您应该替换:

fd.append("filedata", pdfbase64);

与:

fd.append("filedata", new Blob([pdfbase64], {type: 'application/pdf'}););
