iOS开发之使用AFN上传图片

//1.创建管理者对象

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

manager.responseSerializer = [AFJSONResponseSerializer serializer];

manager.requestSerializer = [AFJSONRequestSerializer serializer];

//2.上传文件

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:@"userHeader.png", @"userHeader", nil nil];

[manager POST:URL parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {

//上传文件参数

[formData appendPartWithFileData:data name:@"userHeader" fileName:@"userHeader.png" mimeType:@"image/jpeg"];

} progress:^(NSProgress * _Nonnull uploadProgress) {

//打印上传进度

CGFloat progress = 100.0 * uploadProgress.completedUnitCount / uploadProgress.totalUnitCount;

DLog(@"%.2lf%%", progress);

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

//请求成功

DLog(@"请求成功：%@",responseObject);

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

//请求失败

DLog(@"请求失败：%@",error);

}];

二、多张图片

[objc] view plain copy

//1.创建管理者对象

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

manager.responseSerializer = [AFJSONResponseSerializer serializer];

manager.requestSerializer = [AFJSONRequestSerializer serializer];

//2.上传文件

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:@"userHeader.png", @"userHeader", @"image.png", @"image", nil nil];

[manager POST:URL parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {

//上传文件参数

[formData appendPartWithFileData:data1 name:@"userHeader" fileName:@"userHeader.png" mimeType:@"image/jpeg"];

[formData appendPartWithFileData:data2 name:@"image" fileName:@"image.png" mimeType:@"image/jpeg"];

} progress:^(NSProgress * _Nonnull uploadProgress) {

//打印上传进度

CGFloat progress = 100.0 * uploadProgress.completedUnitCount / uploadProgress.totalUnitCount;

DLog(@"%.2lf%%", progress);

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

//请求成功

DLog(@"请求成功：%@",responseObject);

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

//请求失败

DLog(@"请求失败：%@",error);

}];
