Ios Jsonobject+；图像多部分AFN网络

我们正在尝试使用AFNetworking向服务器发送多部分请求。我们需要发送一个json对象和两个图像文件。下面是对相同的curl请求

curl-X POSThttp://localhost:8080/Circle/restapi/offer/add -H“内容类型：多部分/表格数据”-F“offerDTO={“code”：null，“name”：“Merry X'Mas-1”，“备注”：“每次购买25%折扣”，“validityDate”：“22-12-2014”，“domainCode”：“DO-1”，“merchantCode”：“M-4”，“isApproved”：false，“折扣值”：25，“折扣类型”：“百分比”}；type=application/json“-F”image=@Team Page.png；type=image/png“-F”信头=@Team Page.png；type=image/png“

我知道这应该是相当容易的，因为我已经实现了服务器以及相同的android代码。我的朋友正在做iOS的部分工作。我也在谷歌上搜索了很多，但没有得到任何有用的东西。所以，我知道这违反了StackOverflow的规则，但你们能给我使用AfNetworking的代码吗？如果没有，请将我重定向到同一行的示例

编辑： 请查找我们尝试的以下代码：

UIImage *imageToPost = [UIImage imageNamed:@"1.png"];
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);

一些观察结果：

您的示例是AFNetworking 1.x。AFNetworking 3.x格式副本可能如下所示：

NSURL *fileURL = [[NSBundle mainBundle] URLForResource:@"1" withExtension:@"png"];

// If you need to build dictionary dynamically as in your question, that's fine,
// but sometimes array literals are more concise way if the structure of
// the dictionary is always the same.

// Also note that these keys do _not_ match what are present in the `curl`
// so please double check these keys (e.g. `discountDiscription` vs
// `discountDescription` vs `name`)!

NSDictionary *offerDTO = @{@"code"                : @"",
                           @"discountDescription" : @"Testing",
                           @"remark"              : @"Test",
                           @"validityDate"        : @"07-05-2015",
                           @"creatorCode"         : @"C-7",

// `AFHTTPSessionManager` is AFNetworking 3.x equivalent to `AFHTTPClient` in AFNetworking 1.x

NSURL *baseURL = [NSURL URLWithString:@"http://serverurl:8180"];
