AFNetworking 2.0 和3.0+ 设置请求头Head

我项目里网络请求的Content-Type是application/octet-stream;charset=utf-8。

这种方式跟application/json的不一样，请求参数是二进制的数据流形式的，必须放到body里面去请求。所以问题来了，之前项目用的AFNetworking是2.5.+ 的，现在更新了AFNetworking到3.0+，发现之前的网络请求的AFHTTPRequestOperation被废弃了。现在用AFHTTPSessionManager代替了。不知道怎么设置Header？？

AFNetworking 2.0+ 设置请求头

NSMutableURLRequest *jsonRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURLURLWithString:request.stringOfApiURLString]];

jsonRequest.HTTPMethod= @"POST";

NSMutableData *postBody = [NSMutableData data];intmsgid = request.msgid;

NSData *dataMsgid = [NSData dataWithBytes:&msgid length:4];

[postBody appendData:dataMsgid];

AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:jsonRequest];

[op.securityPolicysetAllowInvalidCertificates:YES];

[op.securityPolicysetValidatesDomainName:NO];

[op.securityPolicysetValidatesCertificateChain:NO];

op.responseSerializer= [AFHTTPResponseSerializer serializer];

[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation,idresponseObj){//处理数据}

} failure:^(AFHTTPRequestOperation *operation,NSError*error) {if(failure) {

failure(error);NSString*str = [[NSStringalloc]initWithData:operation.responseObjectencoding:NSUTF8StringEncoding];NSLog(@"--- request error  %@",str);

}

}];

[[NSOperationQueue mainQueue] addOperation:op];

AFNetworking 3.0+ 设置请求头

NSMutableURLRequest *jsonRequest =[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:request.stringOfApiURLString]];

jsonRequest.HTTPMethod = @"POST";

NSMutableData *postBody = [NSMutableData data];

int msgid = request.msgid;

NSData *dataMsgid = [NSData dataWithBytes:&msgid length:4];

[postBody appendData:dataMsgid];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

[manager setSecurityPolicy:[AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone]];

AFHTTPRequestSerializer *requestSerializer = [AFHTTPRequestSerializer serializer];

[requestSerializer setStringEncoding:NSUTF8StringEncoding];

//    [requestSerializer setTimeoutInterval:10]; [requestSerializer setValue:@"application/octet-stream;charset=utf-8"forHTTPHeaderField:@"Content-Type"];

[manager setRequestSerializer:requestSerializer];

AFHTTPResponseSerializer *responseSerializer = [AFHTTPResponseSerializer serializer];

[responseSerializer setAcceptableContentTypes:[NSSet setWithObjects:@"application/octet-stream",nil]];

[manager setResponseSerializer:responseSerializer];

[[manager dataTaskWithRequest:request completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

if (!error) {

NSLog(@"Reply JSON: %@", responseObject);

if ([responseObject isKindOfClass:[NSDictionary class]]) {

//处理你的数据

}

}else{

NSLog(@"Error: %@, %@, %@",error, response, responseObject);

}

}] resume];
