錯誤==由於格式不正確，無法讀取數據。 當我使用AFNetworking請求

Question

當我請求網絡時：

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

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

        [SVProgressHUD showSuccessWithStatus:@"注冊成功"];

        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:@"注冊失敗"];
    }

} failBlcok:^{
    SVNoNet;
}];

請求網絡時出現錯誤：

[Mysevers AFPOSTWithHud：andAddressname：parmas：RequestSuccess：failBlcok：] _ block_invoke.47] [行號：57] error ==由於格式不正確，無法讀取數據。

Mysevers代碼如下：

@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，否則會返回500錯
        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acceptableContentTypes如下：

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

更新

我將我的sharedHTTPSession更改為：

+ (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，否則會返回500錯
        requestManager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];
    });
    return requestManager;
}

仍然會收到此錯誤。

PHPer打印$_POST ，它是一個空數組。

---

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

結果是PHPer返回給我，他定義了msg ，只是$_POST為空。

在我的AFHTTPSessionManager.m ，向請求標頭添加一行：

#pragma mark - add by me

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

在我的AFHTTPSessionManager.m ：

如果我使用postman的要求，我將成功。

我不知道表單數據是否是原因。

我發現您的郵遞員的param-data類型是form-data ，所以我認為您應該使用AFNetworking的form-submit方法：

試試下面的代碼：

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);
    }];
