与Angular中的其他字段一起发送FormData

不要序列

FormData

POST

this.uploadFileToUrl = function(file, title, text, uploadUrl){    var payload = new FormData();    payload.append("title", title);    payload.append('text', text);    payload.append('file', file);    return $http({        url: uploadUrl,        method: 'POST',        data: payload,        //assign content-type as undefined, the browser        //will assign the correct boundary for us        headers: { 'Content-Type': undefined},        //prevents serializing payload.  don't do it.        transformRequest: angular.identity    });}

然后使用它：

MyService.uploadFileToUrl(file, title, text, uploadUrl).then(successCallback).catch(errorCallback);
