objective-c - uiwebview XMLHttpRequest 例外 101

Question

iOS アプリケーションでリモート プロシージャを実行するために uiwebview を使用しています。これらのリモート プロシージャは、ローカル http サーバーに対して特定の ajax 要求を実行できます。これにより、正しい応答ハンドラーが実行されます。これは、「xmlhttprequest Exception 101」につながるスクリプト全体を再度実行しようとするまで正常に機能します

ハンドラー ajax:

NSString* makeHTMLwithRegisteredHandlers(NSString* serverurl)
{
NSMutableString* output = [NSMutableString new];
if(registeredHandlers != nil)
{
    for(int i=0;i<registeredHandlers.count;i++)
    {
        NSString* scriptfunc = [AbstractRemoteProcedure makeGetJSFromClass:[registeredHandlers objectAtIndex:i]];
        [output appendFormat:@"\nfunction %@(paramdata) { \n",scriptfunc];
        [output appendString:@"\t$.ajax({  \n"];
        [output appendString:@"\t\ttype: \"POST\",  \n"];
        [output appendFormat:@"\t\turl: \"%@/%@\",  \n",serverurl,scriptfunc];
        [output appendString:@"\t\tasync:false,  \n"];
        [output appendString:@"\t\tprocessData: false, \n"];
        [output appendString:@"\t\tdata: paramdata, \n"];
        [output appendString:@"\t\terror: function(xhr, ajaxOptions, thrownError) { \n"];
        [output appendString:@"\t\t\talert(\"runtime exception:\"+thrownError);\n"];
        [output appendString:@"\t\t\tbreakmyJS();\n"];
        [output appendString:@"\t\t},\n"];
        [output appendString:@"\t\tsuccess: function(data) { \n"];
        [output appendString:@"\t\t\tresult = data;  \n"];
        [output appendString:@"\t\t}\n"];
        [output appendString:@"\t});\n"];



        [output appendString:@"\treturn result;\n} \n"];


    }
}
return output;
}

サーバー側スクリプト:

function onConnect()
{
    //device just connected to network
}

function onRetrieve()
{

var req = new Object();
req.url = servertoRequestFrom;
req.usr = deviceIdentifier();
req.pwd = deviceSecret();
var res = HttpCrossDomainSend(jQuery.stringify(req));
var decoded = jQuery.parseJSON(res);
makeSheet(decoded);


}

function onSend()
{
}

function onAuthorize(action)
{
return false;
}
