我使用Golang HTTP请求获取json输出如下.我试图访问的网络服务是Micrsoft Translator https://msdn.microsoft.com/en-us/library/dn876735.aspx

//Data struct of TransformTextResponse
type TransformTextResponse struct {
    ErrorCondition   int    `json:"ec"`       // A positive number representing an error condition
    ErrorDescriptive string `json:"em"`       // A descriptive error message
    Sentence         string `json:"sentence"` // transformed text
}


//some code ....
body, err := ioutil.ReadAll(response.Body)
defer response.Body.Close()
if err != nil {
    return "", tracerr.Wrap(err)
}

transTransform = TransformTextResponse{}
err = json.Unmarshal(body, &transTransform)
if err != nil {
   return "", tracerr.Wrap(err)
}

我收到了一个错误 invalid character 'ï' looking for beginning of …

我需要通过python获得little endian随机字符串.
如'0010'为256(不带'\ x')
这是我的代码.

 import random
 import struct
 str1 = struct.pack('<Q', random.randint(1, 1000))
 #Ex: str1 = '\xc9\x02\x00\x00\x00\x00\x00\x00'

但我不知道将此字符串转换为"C902000000000000"请给出任何建议,谢谢

我刚刚阅读了MSDN，发现这里需要任何建议。

创建委托时，将捕获对外部变量n的引用。与局部变量不同，捕获变量的生存期会延长，直到引用匿名方法的委托才有资格进行垃圾回收。

“已捕获”是否意味着将按值复制？但是我尝试编写一个示例程序，如下所示：

class Program
{

    class async_class
    {
        private int n = 0;

        public async_class()
        {
            for (int i = 0; i <= 9; i++)
            {
                System.Console.WriteLine("Outer  n={0} address={1}", n, n.GetHashCode());
                System.Threading.Thread thread1 = new System.Threading.Thread( () =>
                {
                    System.Console.WriteLine("Inner after n={0} address={1}", ++n, n.GetHashCode());
                });
                thread1.Start();
                //n = 10;
            }

        }

    }

    static void Main(string[] args)
    {
        async_class class1 = new async_class();
     }
}
}

在此示例中，内部“ ++ n”将写回原始外部“ n”。结果就是这样。

外部n = 0地址= 0 …

我只是尝试运行非常简单的Podfile,如下所示

  pod 'AFNetworking', '~> 2.0'  
  pod 'ObjectiveSugar', '~> 0.5'  

但它会得到跟随错误

[!] The `master` repo requires CocoaPods 0.32.1 -
Update CocoaPods, or checkout the appropriate tag in the repo.
/Library/Ruby/Gems/2.0.0/gems/claide-0.4.0/lib/claide/command.rb:217:in `rescue in run': undefined     method `verbose?' for nil:NilClass (NoMethodError)

但我重新安装并双重确认(卸载cocoapods并再次安装)以确保.

gem list --local | grep cocoapods

cocoapods-core (0.33.1)
cocoapods-downloader (0.6.1)
cocoapods-plugins (0.2.0)
cocoapods-trunk (0.1.3)
cocoapods-try (0.3.0)

当我第二次在这里运行时,任何想法或建议都会出现详细的错误日志？

我发现我的代码有不同的结果如下,这是一个指针,指的是Go.Tour编译器(http://tour.golang.org/welcome/1)和我的本地编译器(Go 1.4版)之间的幻灯片

哪一个是正确的？我也想知道我的代码p1,p2之间的指针是如何工作的？因为地址似乎没有移动,但p1使用引用但p2使用副本.

package main

import "fmt"

func main() {
    var a []int
    var b []int
    a = append(a, 0)
    b = append(b, 0)
    p := &a[0]
    fmt.Printf("a[0] = %d pointer=%d, p = %d \n", a[0], &a[0], *p)
    a[0] = 2
    fmt.Printf("a[0] = %d pointer=%d, p = %d \n", a[0], &a[0], *p)
    /*
        a[0] = 0, p = 0
        a[0] = 2, p = 2
    */
    var c []int
    var d []int
    c = append(c, 0)
    d = …
