IOS Post upload image, file stream form

Recently saw a lot of small friends in the group have asked to upload the image server can not receive, parse. It can be said that an attribute ContentType, whether you use a third-party AFN, or your own encapsulation nsurlsesstion. All need to put ContentType settings and the same way in the background (perhaps the term is not very standard, in short, this means Ah, understanding)

The following post a AFN upload image code, pro-Test effective, but may be only for my server. Just communicate with the backstage classmates.

This body is passed to the background parameters, because it is uploading pictures, so just give a picture name is enough, this and backstage to ask

Nsdictionary * BODY = @{@ "category": @ "User" @ "file": @ "headimg"};

Afhttpsessionmanager *manager = [Afhttpsessionmanager manager];

ContentType Settings

Manager.responseSerializer.acceptableContentTypes = [Nsset setwithobjects:@ "Application/json",

@ "Text/html",

@ "Image/jpeg",

@ "Image/png",

@ "Application/octet-stream",

@ "Text/json",

NIL];

manager.requestserializer= [Afhttprequestserializer Serializer];

manager.responseserializer= [Afhttpresponseserializer Serializer];

[Manager Post:url Parameters:body constructingbodywithblock:^ (id<afmultipartformdata> _Nonnull formData) {

Convert image to data, post upload can only transmit data

NSData *data = uiimagepngrepresentation (image);

Uploaded parameters (upload image to file stream format)

[FormData Appendpartwithfiledata:data

name:@ "File"

filename:@ "Gauge.png"

mimetype:@ "Image/png"];

} progress:^ (Nsprogress * _nonnull uploadprogress) {

} success:^ (Nsurlsessiondatatask * _nonnull task, id _nullable responseobject) {

Request a successful block callback

Nsdictionary * dic = [nsjsonserialization jsonobjectwithdata:responseobject options:nsjsonreadingallowfragments Error : nil];

NSLog (@ "Upload successful%@", DIC);

} failure:^ (Nsurlsessiondatatask * _nullable task, Nserror * _nonnull error) {

NSLog (@ "Upload failed%@", error);

}];
