传入json格式的参数

一个大数组里面包含很多个字典

dealdetail_list=[{“dealDetail_id”:”TDealD015475e558fa4392a326d6cc3ccf76ae”,”quantity_sale”:8},{“dealDetail_id”:”TDealD2823fe3e5ee347c0af2fe69a0059870f”,”quantity_sale”:12},{“dealDetail_id”:”TDealD2c698031d55d430ca44eacce1b0b61a5”,”quantity_sale”:1},{“dealDetail_id”:”TDealD354f21896cfb4d45be1c45a1ad87ce89”,”quantity_sale”:13},{“dealDetail_id”:”TDealD4f58e8a3b5df41319c9d32d0fa4e4374”,”quantity_sale”:1},{“dealDetail_id”:”TDealD36d1fc88cad1483b9fd00fe3d9e5563d”,”quantity_sale”:12},{“dealDetail_id”:”TDealD57e07693c68b4655ba82266fdab6033a”,”quantity_sale”:3},{“dealDetail_id”:”TDealD4a3baac99f624e03833d1e9c87d292be”,”quantity_sale”:1.5},{“dealDetail_id”:”TDealD43c0275e8be34398a005dd474ae45ad4”,”quantity_sale”:20},{“dealDetail_id”:”TDealD6833628255184fcb85f87a85041505f5”,”quantity_sale”:1},{“dealDetail_id”:”TDealD73522d1fbfa14f4f87e5590b83471ebf”,”quantity_sale”:6},{“dealDetail_id”:”TDealD6e034caf2e74408f961b19fc29be0b88”,”quantity_sale”:1},{“dealDetail_id”:”TDealDf28dace969d4441ba2cb5d00108f7c41”,”quantity_sale”:1},{“dealDetail_id”:”TDealD898bba51116f4cf49280cc4bba952f60”,”quantity_sale”:1},{“dealDetail_id”:”TDealDfb07cfc7dbab4c21a423b4aa75164ea8”,”quantity_sale”:1},{“dealDetail_id”:”TDealDb5b00d4bb486447291d1039562616d24”,”quantity_sale”:1},{“dealDetail_id”:”TDealDbe807e03199743148ad83ed3323d7726”,”quantity_sale”:1},{“dealDetail_id”:”TDealDfa4902155f2a4a1fa1d19ee53569e01b”,”quantity_sale”:1},{“dealDetail_id”:”TDealDac4df7b3819f43ed8e23b1b5e9c056d1”,”quantity_sale”:1},{“dealDetail_id”:”TDealDb484cca84b494514adc8f957f142ca6d”,”quantity_sale”:5.1},{“dealDetail_id”:”TDealD8f852f109d144c259e97b905fd7011de”,”quantity_sale”:1},{“dealDetail_id”:”TDealDe613f91bd3c44895ac63ef9b7778274b”,”quantity_sale”:12},{“dealDetail_id”:”TDealD7999723d1eb340f394902b4238904ab6”,”quantity_sale”:20},{“dealDetail_id”:”TDealDb5632d1a96544095bf7d578aa847cd39”,”quantity_sale”:1},{“dealDetail_id”:”TDealDbc6052c8d8bd459aa0856c4e598957f9”,”quantity_sale”:6},{“dealDetail_id”:”TDealD74ce90d8e5094da1b4e729354293cbe2”,”quantity_sale”:20},{“dealDetail_id”:”TDealDc62f0d6cd88149aa9c878acccbcdeef2”,”quantity_sale”:3},{“dealDetail_id”:”TDealDa183bd9bb7804b78a904810e8851eee6”,”quantity_sale”:1},{“dealDetail_id”:”TDealDfff0b44e9f99456186922eb47f5b5c7a”,”quantity_sale”:9}]

应该这么写

NSString *jsonStr = nil;

NSMutableArray *goodsArray = [NSMutableArray array];

for (int i = 0; i < _confirmQuantityTV.conGoodsArray.count; i++) {

GoodsModel *model = _confirmQuantityTV.conGoodsArray[i];
jsonStr = [NSString stringWithFormat:@"{\"dealDetail_id\":\"%@\",\"quantity_sale\":%@}",model.dealDetail_id,model.goods_count];

[goodsArray addObject:jsonStr];

}//拼接字符串

NSString *goods_arrayStr = [goodsArray componentsJoinedByString:@","];
NSString *goods_array = [NSString stringWithFormat:@"[%@]",goods_arrayStr];

遍历数组把数组里面的字典拼接起来提交给后台
