我有一些服务将文件上传到我的服务器，然后我的服务器转换文件。我使用这样的服务：
uploadService.uploadFileWaitForConversion(fileToUpload).then(
function(fileid) {
console.log("Upload success");
console.log(fileid);
},
function(error) {
console.log("error uploading");
);
);
服务代码：
// Checks the progress of the conversion. Success means it's done. 409 means it's still converting
function checkFileStatus(uuid, attempts) {
return $http.get('/api/upload/' + uuid, {
}).then(
function (response) {
console.log("File been converted and file uuid returned");
return response.data;
},
function (error) { // API returns 409 if it's still being processed
console.log(attempts);
if (error.status === 409) {
attempts--;
if (attempts > 0) {
$timeout(function () {
checkFileStatus(uuid, attempts)
}, 2000);
} else {
}
}
}
);
}
function uploadFileWaitForConversion(fileToUpload) {
return $upload.upload({
url: '/api/upload',
file: fileToUpload
}).then(
function (response) {
var fileID = response.data.file;
console.log("File uploaded, now let's convert");
return checkFileStatus(fileID, 5).then(
function() {
console.log("Conversion done!");
return fileID;
},
function() {
return 0;
}
);
},
function (error) {
return 0;
}
);
}
我希望打印出来：
相反，这会打印：
