AFN經典報錯bug(三)

AFN經典報錯bug(三)

1. 報錯以下:

[NSURL length]: unrecognized selector sent to instance 0x7fcbb2e72440

2.打全局斷點

鎖定到 NSMutableURLRequest *request = [self.requestSerializer requestWithMethod:method URLString:[[NSURL URLWithString:URLString relativeToURL:self.baseURL] absoluteString] parameters:parameters error:&serializationError];

3.緣由是因爲  url 類型不匹配

 NSString * _urlStr = @"http://iosapi.baidu.cn/doctor/matchedDoctorCount.json.php";

    NSURL * _url = [NSURL URLWithString:_urlStr];

 [_httpManger POST:_url parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {

        NSLog(@"uploadProgress------------------%@",uploadProgress);

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

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

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

        NSLog(@"error------------------%@",error);

    }];

4. 須要nsstring類型 拼接的是NSURL類型

5.修改 [_httpManger POST:_urlStr parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {

        NSLog(@"uploadProgress------------------%@",uploadProgress);

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

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

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

        NSLog(@"error------------------%@",error);

    }];

6. 運行success
