Question

这就是我发送POST请求的方式：

{if (![[NetworkManager sharedManager] connected]) {

    [[NetworkManager sharedManager].requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [NetworkManager sharedManager].responseSerializer.acceptableContentTypes=[NSSet setWithObject:@"application/json"];

    [[NetworkManager sharedManager] POST:url parameters:param progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        if (responseObject != nil) {
             NSLog(@"JSON === %@",responseObject);
            successBlock(responseObject,task);
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (error != nil) {
            failureBlock(error,task);
        }
    }];
}else
{
    failureBlock(nil,nil);

        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            [[UIApplication sharedApplication].keyWindow makeToast:@"Please check your internet connection"
                                                          duration:2.0
                                                          position:CSToastPositionBottom];
        });

}}

但是我收到错误“请求失败：不可接受的内容类型：text / html”。我正在使用AFNetworking。请帮忙!!

@Ghazalah试试这个..

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    [manager POST:url parameters:dictParam progress:^(NSProgress * _Nonnull uploadProgress)
         {

         } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject)
         {
             DLog(@"JSON: %@", responseObject);
             if (dataBlock)
             {
                 if(responseObject==nil)
                     dataBlock(task.response,nil);
                 else
                     dataBlock(responseObject,nil);
             }
         } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error)
         {
             DLog(@"Error: %@", error);
             if (dataBlock) {
                 dataBlock(nil,error);
             }
         }];

当您的服务器发送@＆＃34; text / html＆＃34;而不是已经支持的类型（@＆＃34; application / json＆＃34;）。我的解决方案是添加＆＃34; text / html＆＃34;到AFURLResponseSerialization类中设置的acceptableContentTypes。只需搜索＆＃34; acceptableContentTypes＆＃34;并添加@＆＃34; text / html＆＃34;到手动设置。

    {
    if (![[NetworkManager sharedManager] connected]) {

        [[NetworkManager sharedManager].requestSerializer setValue:@"text/html" forHTTPHeaderField:@"Content-Type"];
        [NetworkManager sharedManager].responseSerializer.acceptableC‌ontentTypes = [[NetworkManager sharedManager].responseSerializer.acceptable‌ContentTypes setByAddingObject:@"text/html"];

        [[NetworkManager sharedManager] POST:url parameters:param progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
            if (responseObject != nil) {
                NSLog(@"JSON === %@",responseObject);
                successBlock(responseObject,task);
            }
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
            if (error != nil) {
                failureBlock(error,task);
            }
        }];
    }
    else{
        failureBlock(nil,nil);

        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            [[UIApplication sharedApplication].keyWindow makeToast:@"Please check your internet connection"
            duration:2.0 position:CSToastPositionBottom];
        });

    }
}

理想的解决方案是更改从服务器发送的类型，但为此，您必须与服务器团队交谈。
