IOS uses AFN for single and multi-image uploads

Reprinted from: Http://www.jianshu.com/p/0e28fdef0f91

Images must be compressed when uploading, otherwise it will fail to upload

1. Single image upload

Afhttprequestoperationmanager *manager = [Afhttprequestoperationmanager manager]; [Manager post:urlstring Parameters:params constructingbodywithblock:^ (id_nonnull formData) {

Use date to generate picture name

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) {

Upload image successfully executed callback

Completion (RESPONSEOBJECT,NIL);

} failure:^ (Afhttprequestoperation * _nonnull operation, Nserror * _nonnull error) {

Upload image failed to execute callback

Completion (NIL,ERROR);

}];

2. Multi-image upload

The difference between multi-image uploads and single-image uploads is the file name

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);

}];
