AFNetworking 2.5.3 序列化数组以显式发送索引
AFNetworking 2.5.3 Serialization of array to send indexes explicitely
我用
AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];
这会在具有以下格式的数组时向服务器发出调用:
payments[]
payments[][email]=0&
payments[][category]=&
payments[][email]=1&
payments[][category]=&
我需要服务器的索引。
payments[]
payments[0][email]=0&
payments[0][category]=&
payments[1][email]=1&
payments[1][category]=&
我怎样才能做到这一点?
谢谢。
AFHTTPRequestSerializer
有一个方法 setQueryStringSerializationWithBlock
允许您提供自己的块来序列化参数。
很遗憾,the internal AF*
functions for serialization are private, but you can copy them and make a small modification in these lines 添加了索引。
设置您自己的序列化块:
[serializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError *__autoreleasing *error) {
return ZAFQueryStringFromParametersWithEncoding(parameters, serializer.stringEncoding);
}];
包括代码,其中 AFNetworking 函数已被复制并以 Z
到 ZAF
为前缀:
static NSString * const kAFCharactersToBeEscapedInQueryString = @":/?&=;+!@#$()',*";
static NSString * AFPercentEscapedQueryStringKeyFromStringWithEncoding(NSString *string, NSStringEncoding encoding) {
static NSString * const kAFCharactersToLeaveUnescapedInQueryStringPairKey = @"[].";
return (__bridge_transfer NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (__bridge CFStringRef)string, (__bridge CFStringRef)kAFCharactersToLeaveUnescapedInQueryStringPairKey, (__bridge CFStringRef)kAFCharactersToBeEscapedInQueryString, CFStringConvertNSStringEncodingToEncoding(encoding));
