需求

后臺(tái)要求post方式調(diào)接口，參數(shù)只有一個(gè)字符串比如@"value"而非@{@"key":@"value"}。感覺(jué)總是有哪里和平時(shí)調(diào)接口不對(duì)，正常單獨(dú)字符串參數(shù)（非json類(lèi)型）的，都采取的是get方式，post一般傳遞的都是一個(gè)字典。后來(lái)找到方法，記錄下來(lái)，以備后用，有同樣疑惑的童鞋可以拿來(lái)用。

方法

/**
 *  異步POST請(qǐng)求:以body方式,支持?jǐn)?shù)組
 *
 *  @param url     請(qǐng)求的url
 *  @param body    body數(shù)據(jù)（NSString 轉(zhuǎn)為utf8編碼的NSData就行）
 *  @param success 成功回調(diào)
 *  @param failure 失敗回調(diào)
