AFNetworking return 400 bad request

问题

i want to post image by AFNetworking,here is the code

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
[manager POST:URL parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){
     [formData appendPartWithFileData:UIImageJPEGRepresentation(selfPhoto, 1) name:@"file" fileName:imageFilePath mimeType:@"image/jpg"];
 }

but return 400 bad request,here is the errro:

Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: bad request (400)" UserInfo={com.alamofire.serialization.response.error.response= { URL: http://121.42.203.122:8080/8minutes/uploadImg } { status code: 400, headers { Connection = close; "Content-Language" = en; "Content-Length" = 1105; "Content-Type" = "text/html;charset=utf-8"; Date = "Fri, 11 Dec 2015 05:36:46 GMT"; Server = "Apache-Coyote/1.1"; } }

here is webservice url key:

  param:{"file"}

where i was wrong?

回答1:

Its because the response you are getting is in "text/html" format it should be in application/json format.

回答2:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];

try this ...worked for me ...
