Question

当我请求网络时：

[Mysevers AFPOSTWithHud:YES andAddressname:@"Common/Currency/Register" parmas:params RequestSuccess:^(id result) {

    if ([result[@"status"] intValue] == 200) {

        [SVProgressHUD showSuccessWithStatus:@"注册成功"];

        UIViewController *temp_vc = nil;

        for (UIViewController *vc in self.navigationController.childViewControllers) {

            if ([vc isKindOfClass:[HomeVC class]] ) {

                temp_vc = vc;
                break;
            }
        }

        if (temp_vc == nil) {
            return;
        }

        [self.navigationController popToViewController:temp_vc animated:YES];

    }else {

        [SVProgressHUD showErrorWithStatus:@"注册失败"];
    }

} failBlcok:^{
    SVNoNet;
}];

我在申请网络时遇到错误：

[Mysevers AFPOSTWithHud：andAddressname：parmas：RequestSuccess：failBlcok：] _ block_invoke.47] [行号：57]错误==无法读取数据，因为格式不正确。

Mysevers代码如下：

@implementation Mysevers

+ (AFHTTPSessionManager *)sharedHTTPSession{
    static dispatch_once_t onceToken;
    static AFHTTPSessionManager *requestManager ;
    dispatch_once(&onceToken, ^{
        requestManager = [AFHTTPSessionManager manager];
        requestManager.requestSerializer.timeoutInterval = 10;
        requestManager.requestSerializer = [AFJSONRequestSerializer serializer];  // 添加，否则会返回500错
        requestManager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];
    });
    return requestManager;
}


+(void)AFPOSTWithHud:(BOOL)hud andAddressname:(NSString*)addressName parmas:(NSDictionary*)parmas RequestSuccess:(void(^)(id result))success failBlcok:(void(^)(void))failBlcok
{
    if (hud) {
        //[HUD addHUD];

        [SVProgressHUD show];
    }

    AFHTTPSessionManager *requestManager = [Mysevers sharedHTTPSession];
    //requestManager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

    NSString *urlStr = [NSString stringWithFormat:@"%@%@",BASE_URL,addressName];
    DLog(@"%@",urlStr);

    [requestManager POST:urlStr parameters:parmas progress:^(NSProgress * _Nonnull uploadProgress) {

    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        if (hud) {
            //[HUD removeHUD];
            [SVProgressHUD dismiss];
        }
        success(responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

        if (error != nil) {
            DLog(@"error==%@",[error localizedDescription]);
            if (hud) {
                //[HUD removeHUD];
                [SVProgressHUD dismiss];
            }
            failBlcok();
        }


        return ;
    }];


}

注意，我的acceptedContentTypes如下：

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

更新

我将sharedHTTPSession更改为：

+ (AFHTTPSessionManager *)sharedHTTPSession{
    static dispatch_once_t onceToken;
    static AFHTTPSessionManager *requestManager ;
    dispatch_once(&onceToken, ^{
        requestManager = [AFHTTPSessionManager manager];
        requestManager.requestSerializer.timeoutInterval = 10;
        AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
        [serializer setStringEncoding:NSUTF8StringEncoding];
        requestManager.requestSerializer=serializer;
        //requestManager.requestSerializer = [AFJSONRequestSerializer serializer];  // 添加，否则会返回500错
        requestManager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];
    });
    return requestManager;
}

仍然会收到此错误。

PHPer打印$_POST，它是一个空数组。

(lldb) po result
{
    data = "";
    msg = 2001;
    status = 400;
}

结果是PHPer返回给我，msg是他定义的，只有$_POST是空的。

在我的AFHTTPSessionManager.m中，我在请求标题中添加了一行：

#pragma mark - add by me

        [request addValue:API_KEY forHTTPHeaderField:@"PUBLICKEY"];

在我的AFHTTPSessionManager.m：

如果我使用postman请求，我会成功。

我不知道表单数据是否是原因。

我发现你的邮递员的参数数据类型是form-data，所以我认为你应该使用AFNetworking的表单提交方法：

尝试以下代码：

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

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

    NSDictionary *params = @{
                             @"UserName":@"admin5",
                             @"Password":@"123456"
                             };


    [manager POST:@"your url" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

        NSLog(@"formData=%@", formData);

    } progress:^(NSProgress * _Nonnull uploadProgress) {

    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

        NSLog(@"responseObject=%@", responseObject);

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"error=%@", error);
    }];

error ==无法读取数据，因为格式不正确。当我使用AFNetworking请求时
