ios - AFNetworking 2.5.3 数组序列化以显式发送索引

                                            <p><p>我用</p>

<pre><code>AFHTTPRequestSerializer *serializer = ;
</code></pre>

<p>当数组的格式为:</p>

<pre><code>payments[]
payments[]=0&amp;
payments[]=&amp;

payments[]=1&amp;
payments[]=&amp;
</code></pre>

<p>我需要类似服务器的索引。</p>

<pre><code>payments[]
payments=0&amp;
payments=&amp;

payments=1&amp;
payments=&amp;
</code></pre>

<p>我怎样才能做到这一点？</p>

<p>谢谢。</p></p>

                                            <p><p><code>AFHTTPRequestSerializer</code> 有一个方法 <a href="https://github.com/AFNetworking/AFNetworking/blob/2.5.3/AFNetworking/AFURLRequestSerialization.h#L195" rel="noreferrer noopener nofollow"><code>setQueryStringSerializationWithBlock</code></a>它允许您提供自己的 block 来序列化参数。 </p>

<p>很遗憾，<a href="https://github.com/AFNetworking/AFNetworking/blob/2.5.3/AFNetworking/AFURLRequestSerialization.m#L65-L159" rel="noreferrer noopener nofollow">the internal <code>AF*</code> functions for serialization</a>是私有(private)的，但您可以复制它们并在 <a href="https://github.com/AFNetworking/AFNetworking/blob/2.5.3/AFNetworking/AFURLRequestSerialization.m#L144-L148" rel="noreferrer noopener nofollow">these lines</a> 中进行小修改添加索引。 </p>

<p>设置你自己的序列化 block :</p>

<pre><code>[serializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError *__autoreleasing *error) {
    return ZAFQueryStringFromParametersWithEncoding(parameters, serializer.stringEncoding);
}];
</code></pre>

<p>包括代码，其中 AFNetworking 函数已被复制并以 <code>Z</code> 为前缀到 <code>ZAF</code>:</p>

<pre><code>static NSString * const kAFCharactersToBeEscapedInQueryString = @&#34;:/?&amp;=;+!@#$()&#39;,*&#34;;

static NSString * AFPercentEscapedQueryStringKeyFromStringWithEncoding(NSString *string, NSStringEncoding encoding) {
    static NSString * const kAFCharactersToLeaveUnescapedInQueryStringPairKey = @&#34;[].&#34;;

    return (__bridge_transferNSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (__bridge CFStringRef)string, (__bridge CFStringRef)kAFCharactersToLeaveUnescapedInQueryStringPairKey, (__bridge CFStringRef)kAFCharactersToBeEscapedInQueryString, CFStringConvertNSStringEncodingToEncoding(encoding));
}

static NSString * AFPercentEscapedQueryStringValueFromStringWithEncoding(NSString *string, NSStringEncoding encoding) {
    return (__bridge_transferNSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (__bridge CFStringRef)string, NULL, (__bridge CFStringRef)kAFCharactersToBeEscapedInQueryString, CFStringConvertNSStringEncodingToEncoding(encoding));
}
