Question

这总是错误-1004（无法连接到服务器）但浏览器中的请求工作正常。我的代码出了什么问题？

(url : "http://localhost:3000/v1/voice/version?appname=wevoice")


AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

manager.responseSerializer = [AFJSONResponseSerializer serializer];

[manager GET:@"http://localhost:3000/v1/voice/version"
  parameters:@{ @"appname": @"wevoice" }
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
}
     failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

Answer 1

您必须在请求管理器上设置属性baseURL。这是一个例子：

self.requestManager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:http://localhost:3000];

稍后，在您向经理发送的具体GET消息中，您只会传递相对的URL路径：

[self.requestManager GET:@"/v1/voice/version"
  parameters:@{ @"appname": @"wevoice" }
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
     NSLog(@"JSON: %@", responseObject);
}
 failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"Error: %@", error);
}];

请记住，如果您想将您的参数作为JSON发送，那么您需要一个请求序列化程序：

self.requestManager.requestSerializer = [AFJSONRequestSerializer serializer];

Answer 2

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

NSMutableDictionary *dic = [NSMutableDictionary dictionary];
[dic setObject:@"wevoice" forKey:@"appname"];

[manager GET:@"http://localhost:3000/v1/voice/version"
  parameters:dic
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
         NSLog(@"JSON: %@", responseObject);
     }
     failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         NSLog(@"Error: %@", error);
     }];

你可以试试这个。可能你添加的方式参数错误。

试试这个方法。希望它有所帮助。

+ (void)getRequestWithURLStringWithSuccess:(void(^)(id object))successBlock andFail:(void(^)(NSString *errorMessage))failBlock {

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc]initWithBaseURL:[NSURL URLWithString:@"http://localhost:3000/v1/voice/version"]];

NSString *urlString = @"/version";

[manager GET:urlString parameters:@{ @"appname": @"wevoice" } success:^(AFHTTPRequestOperation *operation, id responseObject)
 {
     NSLog(@"JSON: %@", responseObject);

 } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"Error: %@", error);

 }];

}

带有查询的AFNetworking GET请求无效
