我正在开发一个office 365 word web 插件，其中我需要将当前打开的文档上传到我的服务器。我正在尝试使用以下代码获取文件数据。
getSliceAsync()方法只返回第一片数据。在调试时它给出“插件错误：抱歉，我们不得不重新启动，因为这个插件没有响应”，同时获得第二个切片。
我正在使用此链接作为参考：[https://docs.microsoft.com/en-us/office/dev/add-ins/word/get-the-whole-document-from-an-add-in-for -字][1]
这是我的代码：
Office.context.document.getFileAsync(Office.FileType.Compressed, { sliceSize: 65536 }, function (result) {
if (result.status == "succeeded") {
// If the getFileAsync call succeeded, then result.value will return a valid File Object
var myFile = result.value;
var filename1 = myFile.name;
console.log(filename1);
var sliceCount = myFile.sliceCount;
var slicesReceived = 0, isAllSlicesSuccess = true, docdataSlices = [];
// document.getElementById("result").innerText = "File size:" + myFile.size + "#Slices: " + sliceCount;
console.log(" File size:" + myFile.size + " #Slices: " + sliceCount, "");
makeProgress(20);
// Iterate over the file slices
for (var i = 0; i < sliceCount && isAllSlicesSuccess; i++) {
var diffPercent = ((i / sliceCount) * 100);
myFile.getSliceAsync(i, function (sliceResult) {
if (sliceResult.status == "succeeded") {
if (!isAllSlicesSuccess) { // Some slice has failed to get, no need to continue
console.log("Error", "One slice failed to get");
return;
console.log(sliceResult);
}
console.log('sliceResult', sliceResult);
console.log("Success", "i: " + i);
console.log("++slicesReceived ",slicesReceived );
console.log(" sliceCount",sliceCount );
console.log("++slicesReceived == sliceCount",slicesReceived == sliceCount);
// One chunk was got, store it in a temporal array
// ++slicesReceived;
// or you can do something with the chunk, such as sent it to a third party server
docdataSlices[sliceResult.value.index] = sliceResult.value.data;
if (++slicesReceived == sliceCount) {
getAllSlicesTime = Date.now();
var performance = (getAllSlicesTime - startTime) / 1000.0;
console.log("Success", "All slices has been get, Seconds: " + performance);
// All slices have been received
myFile.closeAsync(function (closeRes) {
if (closeRes.status == "succeeded") {
console.log("Close Success", "Success");
// DUClick();
}
else {
console.log("Close Error", closeRes.error.message);
}
});
onGetAllSlicesSucceeded(docdataSlices, false);
}
}
else {
isAllSlicesSuccess = false;
myFile.closeAsync(function (closeRes) {
if (closeRes.status == "succeeded") {
console.log("Close Success", "Success");
// DUClick();
}
else {
console.log("Close Error", closeRes.error.message);
}
});
console.log("Get Slice Error:", sliceResult.error.message);
}
});
}
}
else {
getFileTime = Date.now();
var performance = (getFileTime - startTime) / 1000.0;
console.log('Get File Error:', "Seconds: " + performance + " " + result.error.message);
}
});
