我用AFN发送一个GET请求，返回来却报一个错
我的代码如下
+ (void) get:(NSString *)url parameters:(NSDictionary *)params success:(void (^)(id responseObj))success failure:(void (^)(NSError *error))failure;
{
//获得请求管理者
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];//请求
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithArray:@[@"text/html",@"text/plain"]];
[manager GET:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"%@", operation.request.URL);
success(responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// NSLog(@"operation: %@" , operation.responseString );
failure(error);
}];
}
返回的错误信息是：
Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Invalid value around character 0.) UserInfo=0x7fcad2a51c30 {NSDebugDescription=Invalid value around character 0., NSUnderlyingError=0x7fcad2aadca0 "Request failed: internal server error (500)"}
我用operation.responseString打印的结果如下：
