【移動應(yīng)用開發(fā)技術(shù)】Android中怎么利用post請求傳遞json數(shù)據(jù)給服務(wù)端

本篇文章給大家分享的是有關(guān)Android中怎么利用post請求傳遞json數(shù)據(jù)給服務(wù)端，在下覺得挺實(shí)用的，因此分享給大家學(xué)習(xí)，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著在下一起來看看吧。入?yún)⒎庋b成JSON，EXAMPLE：{

"uuid":

"iamauuid",

"clientType":

"AND",

"content":

"{\"gender\":\"F\",\"name\":\"TTT\"}"}其中content中是json的object，且要求把content中特殊的字符進(jìn)行轉(zhuǎn)義。主要代碼如下：/**

*

post請求用json的格式傳遞數(shù)據(jù)給服務(wù)器

*

*

@param

callback

*/

public

static

<T>

void

postShareContent(Context

context,

T

saveObject,

final

ShareSaveDataCallback

callback)

{

final

String

uuid

=

StringUtils.generateUUID().replaceAll("-",

"");

//利用Gson來處json數(shù)據(jù)和類模型之間的轉(zhuǎn)化

Gson

gson

=

new

Gson();

//把類模型對象轉(zhuǎn)化成json的數(shù)據(jù)模式

String

contentJson

=

gson.toJson(saveObject);

//用ShareEntity把內(nèi)容給封裝起來，再處理成json的格式

ShareEntity

shareEntity

=

new

ShareEntity();

//uuid本地端生成，有特殊的方法，下面會注解

shareEntity.uuid

=

uuid;

shareEntity.clientType

=

"AND";

shareEntity.content

=

contentJson;

//再用gson.toJson()處理會自動把第二層的object對象的特殊字符轉(zhuǎn)義掉

String

shareJson

=

gson.toJson(shareEntity);

StringEntity

entity

=

null;

try

{

//把要傳給后端的json數(shù)據(jù)，用StringEntity給封裝起來

entity

=

new

StringEntity(shareJson,"UTF-8");

//注明：UTF-8是防止傳給后端時(shí)中文出現(xiàn)亂碼

}

catch

(UnsupportedEncodingException

e)

{

e.printStackTrace();

}

HttpApiClient.postJsonByAccessToken(context,

ApiBaseUrl.getShareUrl(),

entity,

true,

new

ApiResponseHandler()

{

@Override

public

void

onResponse(boolean

success,

JsonObject

jsonObject,

ErrorCode

errCode)

{

super.onResponse(success,

jsonObject,

errCode);

callback.onSaveResult(success,

uuid,

errCode);

}

});

}postJsonByAccessToken的方法：private

static

AsyncHttpClient

mHttpClient

=

new

AsyncHttpClient();

public

static

void

postJsonByAccessToken(Context

context,

String

url,

StringEntity

entity,

boolean

isCompleterUrl,

AsyncHttpResponseHandler

handler)

{

synchronized

(mHttpClient)

{

addHeader(HEADER_TOKEN,

token);

if

(!isCompleterUrl)

{

url

=

getCompleteUrl(url);

}

mHttpClient.post(context,

url,

entity,

ApiParam.CONTENT_TYPE_JSON,

handler);

}

}

contentType的類型為：application/json

/**

public

interface

ApiParam

{

/**

*

json格式

*/

String

CONTENT_TYPE_JSON

=

"application/json";

String

generateUUID()

{

return

UUID.randomUUID().toString();

}數(shù)據(jù)代碼的一部分：{"clientType":"AND",
