新項目中要求把整個請求參數(shù)的json用AES加密生成一個字符串傳給服務(wù)器，本人網(wǎng)絡(luò)庫用的是AFNetworking接谨，加密后試了一下提示“The ... argument is not valid JSON”, 因為請求參數(shù)不是json AFNetworking給自動過濾掉了.查看了AFNetworking的源碼脓豪，只需要找到

- (NSURLRequest *)requestBySerializingRequest:(NSURLRequest *)request
                               withParameters:(id)parameters
                                        error:(NSError *__autoreleasing *)error

方法，做如下修改就可以了扫夜，注釋掉的是源碼部分，希望能幫助到更多的小伙伴堕阔！
