我正在尝试做一个简单的POST请求。但是,结果在Chrome的POSTMAN插件和iOS模拟器中显得不同。NSData正在返回0字节
这里是邮差快照:
正如你所看到的,我得到了retun JSON数据。
这里是我的代码做POST请求:
NSError *error;
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:kPostURL];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPMethod:@"POST"];
NSString *params =[[NSString alloc] initWithFormat:@"fname=%@&lname=%@&email=%@&password=%@&switchid=%d&didflag=%@",fname,lname,email,pass,switchid,flag];
[request setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding]];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(@"response is %@",response);
NSLog(@"erros is %@",error);
NSMutableDictionary * innerJson = [NSJSONSerialization
JSONObjectWithData:data options:kNilOptions error:&error
];
NSLog(@"JSON data is %@",innerJson);
}];
[postDataTask resume];
,当我尝试在调试器打印的价值观,我得到
JSON
为null
和NSData
为0
bytes
。但我得到了status code as 200
,这是成功的。
这里是响应我得到:
{ status code: 200, headers {
Connection = "Keep-Alive";
"Content-Length" = 0;
"Content-Type" = "text/html";
Date = "Thu, 25 Feb 2016 02:04:02 GMT";
"Keep-Alive" = "timeout=5";
Server = "Apache/2.4.12";
"X-Powered-By" = "PHP/5.5.30";
} }
为什么我得到的NSData为0字节?
感谢。有效。 –
