一般请求的话是这样
AFHTTPSessionManager *session = [AFHTTPSessionManager manager];
session.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html", nil];
[session POST:@"" parameters:@"" progress:nil success:nil failure:nil];
但是今天遇到个不管怎么样parameters都传不到服务器那边，而后台那边给我的解释是传输用[request setHTTPBody:data];
而 afn 2.0 是这样的
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters
options:0
error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
// And finally, add it to HTTP body and job done.
[request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval=[[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(@"Reply JSON: %@", responseObject);
}
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request);
}];
[operation start];
但是3.0弃用了AFHTTPRequestOperationManager,那么怎么才能用呢？
1.用系统NSURLConnection 请求
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"url"]];
[request setHTTPBody:data];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (theConnection) {
NSLog(@"connected");
receivedData=[[NSMutableData alloc]init];
} else {
NSLog(@"not connected");
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[receivedData setLength:0];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[receivedData appendData:data];
NSString* responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"response: %@",responseString);
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"Succeeded! Received %lu data",(unsigned long)[receivedData length]);
NSString* responseString = [[NSString alloc] initWithData:receivedData encoding:NSUTF8StringEncoding];
NSLog(@"response: %@",responseString);
NSError *myError = nil;
NSDictionary *res = [NSJSONSerialization JSONObjectWithData:receivedData options:NSJSONReadingMutableLeaves error:&myError];
NSLog(@"%@",res);
}
2.用不习惯系统没关系，其实afn3.0 也有提供api给我们调用，但是这个是我一直没接触过的AFURLSessionManager。
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:@"url" parameters:nil error:nil];
req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setHTTPBody:da];
[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (!error) {
NSLog(@"Reply JSON: %@", responseObject);
} else {
NSLog(@"Error: %@, %@, %@", error, response, responseObject);
}
}] resume];
