IOS AFNetWork 多附件上传_afnetwork多文件上传-优快云博客

本文介绍了使用AFNetworking实现iOS应用中多个文件上传到单一接口的详细步骤，通过构造请求体并枚举文件数据，成功完成批量上传。适用于有类似需求的iOS开发者。

距上一篇IOS AFNETWork 附件上传博文发布已有数月之久，最近在项目中又有了变态的需求在一个页面中有多个附件域，但是接口只有一个。于是边翻看AFNetwork 的api 最终找到了这样一个结构

NSURLSessionDataTask *task = [httpClient POST:url parameters:parame constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

[mutilableBodys enumerateObjectsUsingBlock:^(NSDictionary *cellBodyDic, NSUInteger idx, BOOL *stop) {

[formData appendPartWithFileData:cellBodyDic[@"body"] name:cellBodyDic[@"name"] fileName:cellBodyDic[@"fileName"] mimeType:cellBodyDic[@"mimeType"] ];

}];

} success:^(NSURLSessionDataTask *task, id responseObject) {

if (completBlock) {

completBlock(responseObject,nil);

}

} failure:^(NSURLSessionDataTask *task, NSError *error) {

if (completBlock) {

completBlock(nil,error);

}

}];

最后和服务端测试发现文件上传成功了，兴奋之余写下本文，用作日后查询之用

全文内容如下

+(NSURLSessionDataTask *)upLoadFileSWithAction:(NSString *)url andFileItem:(NSDictionary *)fileItemDic andFileType:(NSDictionary *)fileTypeDic andUploadedSize:(NSUInteger)hsize andParames:(NSDictionary *)parame CompleteBlock:(void(^)(id responseObject,NSError *error))completBlock{

NSMutableArray *mutilableBodys =[NSMutableArray array];

NSArray *fNameKeys = [fileItemDic allKeys];

for (NSString *fNameKey in fNameKeys) {
