Error Domain=com.alamofire.error.serialization.response Code=-1016 image/jpeg application/octet-stre

具体错误代码

error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: image/jpeg" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x170225100> { URL: https:// } { status code: 200, headers {

//1 在这里添加@"image/jpeg"
manager.responseSerializer.acceptableContentTypes = [NSSet setWithArray:@[@"application/json",
@"text/html",
@"text/json",
@"text/plain",
@"text/javascript",
@"text/xml",@"image/jpeg",
@"image/*"]];

//如果出现  error:Error Domain=NSCocoaErrorDomain Code=3840 "JSON text did not start with array or object and option to allow fragments not set." UserInfo={NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}有可能requestSerializer设置不对

// manager.requestSerializer = [AFJSONRequestSerializer serializer];

manager.requestSerializer = [AFHTTPRequestSerializer serializer];
