你好我想发一个ajax电话。我使用Phonegap 2.8.0，jqm 1.3.2和Xcode这里是我的代码
window.SavePhoto= function() {
try{
var txtComment = $('#txtComment').val();
var cameraImage = $('#cameraImage').attr('src');
var request_url = sessionStorage.getItem('CategoryLink');
var X_CSRFToken = sessionStorage.getItem("X_CSRFToken");
console.log('token=' + X_CSRFToken);
console.log('cameraImage==' + cameraImage);
console.log("request_url==" + request_url);
console.log('txtComment==' + txtComment);
if(!cameraImage){
alert('Cannot save without select image','Image Required', 'Ok');
return;
}
$.ajax({
url: request_url ,
type: 'POST',
contentType: 'multipart/form-data',
data:{"comment":txtComment,"photo_file":cameraImage},
headers: {Cookie:cookie_saved,'X-CSRF-Token': X_CSRFToken},
success: function (result,status,xhr) {
if (! status.success) {
} else {
}
alert ('message=' + JSON.stringify(status));
},
error: function (xhr,status,error)
{
alert(JSON.stringify(error));
}
});
}
catch(e){alert(e);}
console.log('save photo function exit');
}
Phonegap应用程序在成功函数发生之前崩溃并给我以下日志。经过分析发现我可能会给出无效的CSRFToken。

花了好几个小时后我发现这个工作。有一点很清楚我们无法通过Ajax Jquery上传照片。我们必须使用filetransfer插件。这是我的工作代码。另一件事我们必须使用cordova 2.9.0而不是cordova 2.8.0，因为相机中有一个错误getpicture FILE_URI
window.SavePhoto= function() {
try{
var txtComment = document.getElementById('txtComments');
var cameraImage = $('#cameraImage').attr('src');
var request_url = sessionStorage.getItem('CategoryLink');
var X_CSRFToken = sessionStorage.getItem('X_CSRFToken');
var cookies= X_CSRFToken;
var lblpath = document.getElementById('lblpath');
var fileURI= lblpath.innerHTML;
if(!cameraImage){
msgAlert('Cannot save without select image','Image Required', 'Ok');
return;
}
var options = new FileUploadOptions();
options.fileKey = "photo_file";
options.mimeType = "image/jpeg";
options.chunkedMode = false;
options.fileName= fileURI.substr(fileURI.lastIndexOf('/')+1);
options.params = {
'comment': txtComment.value
};
options.headers = {
//'X-CSRFToken': csrfToken,
Cookie: cookies
};
console.log('options=' + JSON.stringify( options));
var ft = new FileTransfer();
ft.upload(fileURI, encodeURI(request_url), win, fail, options);
}
catch(e)
{
msgAlert(e);
}
console.log('save photo exit');
}
var win=function (r) {
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
console.log("Sent = " + r.bytesSent);
}
var fail=function (error) {
alert("An error has occurred: Code = " + error.code);
console.log("upload error source " + error.source);
console.log("upload error target " + error.target);
}
