使用服务器将json数据发送到服务器并希望从服务器获取正确的response.statusCode
服务器:
// Helper method to send a HTTP response code/message
function sendResponse($status = 200, $body = '', $content_type = 'text/html')
{
$status_header = 'HTTP/1.1 ' . $status . ' ' . getStatusCodeMessage($status);
header($status_header);
header('Content-type: ' . $content_type);
echo $body;
}
sendResponse(200, json_encode("Files Deleted"));
iOS:
NSURL *url = [NSURL URLWithString:server];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
// don't forget to set parameterEncoding!
httpClient.parameterEncoding = AFJSONParameterEncoding;\
NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:deleteExtraFilesIn parameters:nil];
[request setHTTPBody:[displayJson dataUsingEncoding:NSUTF8StringEncoding]];
[request addValue:@"ASIHTTPRequest" forHTTPHeaderField:@"User-Agent"];
[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSLog(@"request %@",request);
[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];
AFHTTPRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:nil failure:nil];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id response) {
// Print the response body in text
if (operation.response.statusCode == 200) {
NSLog(@"Got you");
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
[operation start];
错误NSLOG:
Error: 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=0x1f519df0 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}
如何在上述代码中获得正确的http响应?
注意:服务器上的
AFNetworking
只是虚拟文本,我想要的是http响应代码。 最佳答案
您需要将操作设置为允许片段:
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:nil failure:nil];
operation.JSONReadingOptions = NSJSONReadingAllowFragments;
