我调用此函数并每次返回Cocoa Error 3840.我尝试调试并修复它,它在请求时出错,而不是在解析结果时出错
我在请求时在故障块中发现了这个错误.
Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x109230960 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not et.}
2013-11-01 12:09:30.925 MagicBox[87431:70b] The operation couldn’t be completed. (Cocoa error 3840.)
这是我的代码在此先感谢.
- (void)loginWithUserName:(NSString *)userName
Password:(NSString *)password
orFacebook:(NSString *)facebookID
withResponseBlock:(ResponseBlock)responseBlock {
if (!userName && !facebookID) {
NSError *error = [NSError errorWithDomain:@"Missing Parameters" …我有以下JSON解析代码:
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.dropbox.com/s/qz16qyi3julygl9/facebook.json"]];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSLog(@"Request Success %@",[JSON class]);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
NSLog(@"Request Failure Because %@",[error userInfo]);
}];
[operation start];
但我有Request Failure并出现以下错误消息:
NSErrorFailingURLKey =" https://www.dropbox.com/s/qz16qyi3julygl9/facebook.json "; NSLocalizedDescription ="预期内容类型{(\n \"text/json \",\n \"application/json \",\n \"text/javascript \"\n)},得到text/html";
有人能帮助我吗？
在本地测试它工作.在不同的港口(3001,8080)
但在测试服务器(Azure)上
我在同一台机器上运行了2个Node App实例
$ node api1/index.js (on port 3000)
$ node api2/index.js (on port 3001)
和
$ node api1/index.js (on port 3001)
$ node api2/index.js (on port 3000)
但它只适用于端口3000.
如何在Express中设置不同的端口？
现在,我已经在index.js的app.listen(3001)上进行了更改,但它无效.
