Question

我需要在发出POST请求时在URL中发送查询字符串以及正文中的JSON。要在网址中发送查询字符串，我会按this thread on SO中的建议覆盖HTTPMethodsEncodingParametersInURI属性

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:fullUrl]];
        manager.requestSerializer = [AFJSONRequestSerializer serializer];
        manager.responseSerializer = [AFJSONResponseSerializer serializer];

        manager.requestSerializer.HTTPMethodsEncodingParametersInURI = [NSSet setWithArray:@[@"POST", @"GET", @"HEAD", @"PUT", @"DELETE"]];



        [manager POST:fullUrl parameters:param success:^(AFHTTPRequestOperation *operation, id responseObject) {
 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
 }];

但似乎这样做也会将我的JSON数据添加到URL中，因此我的请求不会在服务器上执行。但我只需要发送＆＃39;命令＆＃39;参数进入url，一些JSON数据进入请求体。我的fullUrl字符串看起来像http://some_ip_address/config?command=some_command，而param是NSDictionary对象。请注意fullUrl中有一个参数，即命令，我还会在

中发送一个NSDictionary对象 param

[manager POST:fullUrl parameters:param success:^(AFHTTPRequestOperation *operation, id responseObject) {
     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     }];

Edit2：我也试过了NSURLSession

NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:self delegateQueue:nil];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://my_server_ip/config?command=plugs"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
    NSError *error;
    NSData *postData = [NSJSONSerialization dataWithJSONObject:param options:0 error:&error];
    [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:postData];
    NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    }];
    [postDataTask resume];

但获取状态代码：NSURLResponse中的400。

编辑3：有人建议在this SO thread中继承AFHTTPRequestSerializer类，所以我尝试了

@implementation CustomAFHTTPRequestSerializer

-(id)init
{
    self = [super init];
    return self;
}
- (NSMutableURLRequest *)requestWithMethod:(NSString *)method
                                 URLString:(NSString *)URLString
                                parameters:(NSDictionary *)parameters
                                     error:(NSError *__autoreleasing *)error
{
    NSString* encodedUrl = [URLString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:encodedUrl] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
    NSError *error1;
    NSData *postData = [NSJSONSerialization dataWithJSONObject:parameters options:0 error:&error1];
    [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:[NSString stringWithFormat:@"%d", [postData length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:postData];
     return request;
}
@end

并将其指定为operationManager的requestSerializer

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
        manager.requestSerializer = [[CustomAFHTTPRequestSerializer alloc] init];

但仍然得到Error Domain=AFNetworkingErrorDomain Code=-1011 "Request failed: bad request (400)

请帮助我们，非常感谢任何帮助。

AFNetworking2在POST请求中将参数作为查询字符串发送？
