从SharePoint 2013 REST API对文件使用moveto或copyto时出现“格式不正确的JSON流”

Question

I am trying to enable file move and copy operations on files in a sharepoint 2013 document library. I have the list and delete operations working but when I try to call /moveto(newfile=...,flags=1) or /copyto(strnewfile,boverwrite=true) I get an error "Not well formed JSON stream".

I have tried the newurl (or strnewurl) both with and without the site prefix (eg /sites/dev). I have separately verified that getfilebyserverrelativeurl is in fact returning the file.

Has anyone run into this before?

function copyFile() {
    var executor = new SP.RequestExecutor(appweburl);
    executor.executeAsync({
        url: appweburl + "/_api/SP.AppContextSite(@target)/web" +
            "/getfilebyserverrelativeurl('/sites/dev/Sample1/Customer.dim')" +
            "/copyto(strnewurl='/Sample1/filename.docx',boverwrite=false)" +
            "?@target='" + hostweburl + "'",
        method: "POST",
        headers: {
            "accept": "application/json;odata=verbose",
            "IF-MATCH": "*"
        },
        success: function (data) {
            alert(JSON.stringify(data));
        },
        error: errorHandler
    });
}

function moveFile() {
    var executor = new SP.RequestExecutor(appweburl);
    executor.executeAsync({
        url: appweburl + "/_api/SP.AppContextSite(@target)/web" +
            "/getfilebyserverrelativeurl('/sites/dev/Sample1/Customer.dim')" +
            "/moveto(newurl='/Sample1/filename.docx',flags=1)" +
            "?@target='" + hostweburl + "'",
        method: "POST",
        headers: {
            "accept": "application/json;odata=verbose",
            "IF-MATCH": "*",
            "X-RequestDigest": $("#__REQUESTDIGEST").val()
        },
        success: function (data) {
            alert(JSON.stringify(data));
        },
        error: errorHandler
    });
}

Answer 1

I just ran into the same problem. My solution was to use ajax instead of the executor:

 $.ajax({ url: SPAppWebUrl + "/_api/SP.AppContextSite(@target)/web/getfilebyserverrelativeurl('" + file + "')/copyto(strnewurl='" + target + "',boverwrite=false)?@target='" + hostweburl + "'", type: "POST", dataType: 'json', headers: { "Accept": "application/json; odata=verbose", "content-type": "application/json; odata=verbose", "IF-MATCH": "*", "X-RequestDigest": $('#__REQUESTDIGEST').val() }, success: successHandler, error: errorHandler }); 

Strange enough when I use the same with the RequestExecutor it doesn't work.

I've found that the copyto URL parameter needs to be server relative, not site relative. So strnewurl='/sites/dev/Sample1/filename.docx' instead of strnewurl='/Sample1/filename.docx'

I know all the docs say it's site relative, but this is what's worked for me. I also only include the accept header.
