iOS使用AFN进行单图和多图上传的实例代码

图片上传时必要将图片进行压缩,不然会上传失败

1.单张图上传

afhttprequestoperationmanager *manager = [afhttprequestoperationmanager manager];  [manager post:urlstring parameters:params constructingbodywithblock:^(id_nonnull formdata) {

//使用日期生成图片名称

nsdateformatter *formatter = [[nsdateformatter alloc] init];

formatter.dateformat = @"yyyy-mm-dd hh:mm:ss";

nsstring *filename = [nsstring stringwithformat:@"%@.png",[formatter stringfromdate:[nsdate date]]];

[formdata appendpartwithfiledata:imagedata name:@"uploadfile" filename:filename mimetype:@"image/png"];

} success:^(afhttprequestoperation * _nonnull operation, id _nonnull responseobject) {

//上传图片成功执行回调

completion(responseobject,nil);

} failure:^(afhttprequestoperation * _nonnull operation, nserror * _nonnull error) {

//上传图片失败执行回调

completion(nil,error);

}];

2.多图上传

多图上传和单图上传区别在于文件名称

afhttprequestoperationmanager *manager = [afhttprequestoperationmanager manager];  [manager post:urlstring parameters:params constructingbodywithblock:^(id_nonnull formdata) {

nsinteger imgcount = 0;

for (nsdata *imagedata in imagedatas) {

nsdateformatter *formatter = [[nsdateformatter alloc] init];

formatter.dateformat = @"yyyy-mm-dd hh:mm:ss:sss";

nsstring *filename = [nsstring stringwithformat:@"%@%@.png",[formatter stringfromdate:[nsdate date]],@(imgcount)];

[formdata appendpartwithfiledata:imagedata name:[nsstring stringwithformat:@"uploadfile%@",@(imgcount)] filename:filename mimetype:@"image/png"];

imgcount++;

}

} success:^(afhttprequestoperation * _nonnull operation, id _nonnull responseobject) {

completion(responseobject,nil);

} failure:^(afhttprequestoperation * _nonnull operation, nserror * _nonnull error) {

completion(nil,error);

}];
