我最近刚开始使用AFNetworking
,并且在接收来自基于JSON的服务器API的响应标头时遇到了问题。下面是我写的与服务器通信的代码。请求/响应是一个JSON对象。
问题:在阅读响应标头时,我的服务器未添加2个额外的安全密钥。当我使用传统的NSURLConnection
或新的NSURLSession
时,我能够获得它们,但是AFNetworking
API并没有让它们回来。
有任何线索吗?
- (void)makeServerCall {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
// Set Request headers
NSDictionary *securityHeaders = [MyUtilities securityRequestHeaders];
for (NSString *headerKey in securityHeaders) {
[manager.requestSerializer setValue:securityHeaders[headerKey] forHTTPHeaderField:headerKey];
}
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager.responseSerializer.acceptableContentTypes setByAddingObject:@"application/json;charset=UTF-8"];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[manager.requestSerializer setValue:@"gzip" forHTTPHeaderField:@"Accept-Encoding"];
// Make Server Call
[manager POST:self.urlString parameters:self.postBody success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {
if (!self.skipSecurityHeaders) {
[MyUtilities securityResponseHeaders:[operation.response allHeaderFields]];
}
NSLog(@"Received response for %@ \n Response Header %@ \n Response %@", self.urlString, [operation.response allHeaderFields], responseObject);
[self didFinishWithResult1:responseObject andResponse:operation.response];
} failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) {
NSLog(@"Error: %@", error);
}];
}
因此,当我打印[operation.response allHeaderFields]
时,我得到以下输出:
Response Header {
"Cache-Control" = "private, must-revalidate";
"Content-Language" = "en-US";
"Content-Length" = 929;
"Content-Type" = "application/json;charset=UTF-8";
Date = "Mon, 02 May 2016 09:12:52 GMT";
Pragma = private;
Server = "Apache-Coyote/1.1";
"Set-Cookie" = "NSC_JOuoxqqabim3ljwdrzxad5c42hiv0bf=ffffffff12a12ecc45525d5f4f58455e445a4a42378b;path=/;secure;httponly";
}
缺少2个额外的密钥 - 我的服务器发送的key1
和key2
。
答案 0 :(得分:0)
好的,想通了 - 我在设置requestSerializer
之前设置了标题。所以流程应该是 -
- (void)makeServerCall {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager.responseSerializer.acceptableContentTypes setByAddingObject:@"application/json;charset=UTF-8"];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[manager.requestSerializer setValue:@"gzip" forHTTPHeaderField:@"Accept-Encoding"];
// Set Request headers
NSDictionary *securityHeaders = [MyUtilities securityRequestHeaders];
for (NSString *headerKey in securityHeaders) {
[manager.requestSerializer setValue:securityHeaders[headerKey] forHTTPHeaderField:headerKey];
}
RUNNERLOG(@"Executing request for %@ \n Request Header %@ \n Request Body %@", self.urlString, securityHeaders, self.postBody);
// Make Server Call
[manager POST:self.urlString parameters:self.postBody success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) {
if (!self.skipSecurityHeaders) {
[MyUtilities securityResponseHeaders:[operation.response allHeaderFields]];
}
NSLog(@"Received response for %@ \n Response Header %@ \n Response %@", self.urlString, [operation.response allHeaderFields], responseObject);
[self didFinishWithResult1:responseObject andResponse:operation.response];
} failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) {
NSLog(@"Error: %@", error);
}];
}
