微信小程序的API 重写了网络请求和本地缓存的访问方式

所以为了使用parse的js sdk 需要修改这两块

增加localStorage变量

var localStorage = {

getItem:function(path){

return wx.getStorageSync(path);

},

setItem:function(path, value){

return wx.setStorageSync(path, value);

},

removeItem:function(path){

wx.removeStorageSync(path)

},

clear:function(){

wx.clearStorageSync()

}

};

var StorageController = {

async: 0,

getItem: function (path) {

return localStorage.getItem(path);

},

setItem: function (path, value) {

try {

localStorage.setItem(path, value);

} catch (e) {

// Quota exceeded, possibly due to Safari Private Browsing mode

}

},

removeItem: function (path) {

localStorage.removeItem(path);

},

clear: function () {

localStorage.clear();

}

};

StorageController 可以按照浏览器里的方式使用

修改RESTController 增加 wxRequest 方法

wxRequest: function(method, url, data, payloadString,headers){

var promise = new _ParsePromise2.default();

var jsKey = _CoreManager2.default.get('JAVASCRIPT_KEY');

var masterKey = _CoreManager2.default.get('MASTER_KEY');

var appId = _CoreManager2.default.get('APPLICATION_ID');

var payload = JSON.parse(payloadString);

headers = headers || {};

headers["content-type"] = "application/json";

headers["X-Parse-Application-Id"] = appId;

headers["X-Parse-JavaScript-Key"] = jsKey;

if(masterKey){

headers["X-Parse-Master-Key"] = masterKey;

}

wx.request({

url: url,

data: data,

header: headers,

method:payload._method,

success: function(res) {

console.log(res)

var response;

try {

//response = JSON.parse(res.data);

promise.resolve(res.data, res.status, res);

} catch (e) {

promise.reject(e.toString());

}

},

fail: function(err){

console.log(err)

promise.reject(err.toString());

}

});

return promise;

}

//修改请求方法

//return RESTController.ajax(method, url, payloadString);

return RESTController.wxRequest(method, url, data);

//默认的ajax方法替换为微信小程序的网络请求方法
