Ios 使用Cordova/Phonegap通过文件传输发送录制的文件
我正在尝试发送通过媒体插件录制的语音记录 当我尝试发送文件时,收到以下文件错误。未找到错误:Ios 使用Cordova/Phonegap通过文件传输发送录制的文件,ios,cordova,file-upload,media,Ios,Cordova,File Upload,Media,我正在尝试发送通过媒体插件录制的语音记录 当我尝试发送文件时,收到以下文件错误。未找到错误: Error opening file /myRecording100.wav: Error Domain=NSCocoaErrorDomain Code=260 "The operation couldn’t be completed.

但是,我可以在录音后播放语音录音
为什么我能够播放该文件(显示该文件已录制并正确保存),但FileTransfer无法发送该文件?
这是我的代码(用于ios):
由于File plugin的v1.0版本,要通过File transfer plugin在文件系统中上载文件,您需要使用.toURL()方法来访问它 如果要升级到文件的新(1.0.0或更新)版本,以及 您以前使用entry.fullPath作为 download()或upload(),则需要更改代码才能使用 而不是文件系统URL FileEntry.toURL()和DirectoryEntry.toURL()返回文件系统URL 形式 因此正确的代码是:
/* Get the file and send it */
function onOK_GetFile(fileEntry) {
var options = new FileUploadOptions();
options.fileKey = "want";
options.fileName = "file.wav";
options.mimeType = "audio/wav";
options.chunkedMode = false;
options.params = parameters;
var ft = new FileTransfer();
ft.upload(fileEntry.toURL(), "https://SERVER_ADDRESS", win, fail, options);
}
我在iOS上遇到了完全相同的问题,而FileUploadOptions对我不起作用 如果有人也在挣扎,我的解决方案是切换到LocalFileSystem.Temporary 这里有一个片段显示了完整的示例(未在Android上测试): 这里有一些Worklight(调试输出)和dojo(声明),但是这段代码可以作为参考
/* Get the file and send it */
function onOK_GetFile(fileEntry) {
var options = new FileUploadOptions();
options.fileKey = "want";
options.fileName = "file.wav";
options.mimeType = "audio/wav";
options.chunkedMode = false;
options.params = parameters;
var ft = new FileTransfer();
ft.upload(fileEntry.toURL(), "https://SERVER_ADDRESS", win, fail, options);
}
