我正在向Web服務發送HTTP請求,我應該得到一個JSON作爲響應。在Objective C中,responseData不是空的,但它作爲JSON的序列化爲null。這是我的代碼:Objective C JSON對象null但responseData不爲空
- (IBAction)getProfileInfo:(id)sender
{
NSString *code = @"oanure!1";
//Start request
NSURL *url = [NSURL URLWithString:@"http://192.168.1.8:5000/login?json"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:code forKey:@"logincode"];
[request setDelegate:self];
[request startAsynchronous];
}
- (void)requestFinished: (ASIHTTPRequest *) request{
if (request.responseStatusCode == 400){
self.profileInfo.text = @"Invalid code";
} else if (request.responseStatusCode == 403) {
self.profileInfo.text = @"Code alredy used";
} else if (request.responseStatusCode == 200) {
NSData *responseData = [request responseData];
NSLog(@"%@", responseData);
NSError *error;
//I tried with NSDictionary as well
NSArray *json = (NSArray *)
[NSJSONSerialization JSONObjectWithData:responseData
options:kNilOptions
error:&error];
NSLog(@"%@", json);
}
else {
self.profileInfo.text = @"Unexpected error";
}
}
控制檯打印出:

我想我沒有做的系列化權利......
正是如此,證明了網絡服務的工作原理,我用Python編寫了一個小腳本:
import httplib, urllib
params = urllib.urlencode({
'logincode' : 'oanure!1',
})
conn = httplib.HTTPConnection("192.168.1.8:5000")
conn.request("POST", "/login?json",
params)
response = conn.getresponse()
print response.status, response.reason
data = response.read()
print data
conn.close()
在這種情況下,控制檯打印出來: 200 OK { 「的loggedIn」:0, 「錯誤」: 「不登錄」}
我想獲得同樣的事情在目標C.
請幫幫忙!
您的'responseData'包含HTML,而不是JSON。 –
打印出由數據組成的字符串。您可能會立即看到問題。 –
