Post調(diào)用接口并傳遞json參數(shù)

publicstringPost(stringUrl,stringjsonParas)

//創(chuàng)建一個HTTP請求

HttpWebRequestrequest=(HttpWebRequest)WebRequest.Create(strURL);

//Post請求方式

request.Method="POST";

//內(nèi)容類型

request.ContentType="application/json";

//設(shè)置參數(shù)，并進行URL編碼

stringparaUrlCoded=jsonParas;//System.Web.HttpUtility.UrlEncode(jsonParas);

byte[]payload;

//將Json字符串轉(zhuǎn)化為字節(jié)

payload=System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);

//設(shè)置請求的ContentLength

request.ContentLength=payload.Length;

//發(fā)送請求，獲得請求流

Streamwriter;

writer=request.GetRequestStream();//獲取用于寫入請求數(shù)據(jù)的Stream對象

catch(Exception)

Console.Write("連接服務(wù)器失敗!");

//將請求參數(shù)寫入流

writer.Write(payload,0,payload.Length);

Post請求參數(shù)(發(fā)送Json參數(shù)、發(fā)送普通參數(shù))

1.發(fā)送Json格式的Post請求

（1）Post調(diào)用

stringPostUrl="http://IP:端口/AAA/BBB/CCC";

stringid="123";

stringName="小黑";

JObjectpatientinfo=newJObject();

JArrayids=newJArray();

ids.Add(id);

patientinfo["ids"]=ids;

patientinfo["Name"]=Name;

stringsendData=JsonConvert.SerializeObject(patientinfo);

//eg:

發(fā)送Url需要的格式：sendData={"ids":[123],"Name":小黑}

stringresultData=Post(sendData,PostUrl);

（2）Post方法

#regionPost請求

///summary

///httpPost請求

////summary

///paramname="parameterData"參數(shù)/param

///paramname="serviceUrl"訪問地址/param

///paramname="ContentType"默認application/json,application/x-www-form-urlencoded,multipart/form-data,raw,binary/param

///paramname="Accept"默認application/json/param

publicstringPost(stringparameterData,stringserviceUrl,stringContentType="application/json",stringAccept="application/json")

//先根據(jù)用戶請求的uri構(gòu)造請求地址

//stringserviceUrl=string.Format("{0}/{1}",this.BaseUri,uri);

//創(chuàng)建Web訪問對象

HttpWebRequestmyRequest=(HttpWebRequest)WebRequest.Create(serviceUrl);

//把用戶傳過來的數(shù)據(jù)轉(zhuǎn)成“UTF-8”的字節(jié)流

byte[]buf=System.Text.Encoding.GetEncoding("UTF-8").GetBytes(parameterData);

myRequest.AllowAutoRedirect=true;

//myRequest.Headers.Add("content-type","application/json");

//myRequest.Headers.Add("accept-encoding","gzip");

//myRequest.Headers.Add("accept-charset","utf-8");

//發(fā)送請求

Streamstream=myRequest.GetRequestStream();

stream.Write(buf,0,buf.Length);

stream.Close();

//通過Web訪問對象獲取響應(yīng)內(nèi)容

HttpWebResponsemyResponse=(HttpWebResponse)myRequest.GetResponse();

//通過響應(yīng)內(nèi)容流創(chuàng)建StreamReader對象，因為StreamReader更高級更快

StreamReaderreader=newStreamReader(myResponse.GetResponseStream(),Encoding.UTF8);

//stringreturnXml=HttpUtility.UrlDecode(reader.ReadToEnd());//如果有編碼問題就用這個方法

stringreturnData=reader.ReadToEnd();//利用StreamReader就可以從響應(yīng)內(nèi)容從頭讀到尾

reader.Close();

myResponse.Close();

returnreturnData;

2.帶參數(shù)的Post請求

（1）Post調(diào)用

stringPostUrl="http://IP:端口/AAA/BBB/CCC";

Dictionarystring,stringdic=newDictionarystring,string

dic.Add("Id","123");

dic.Add("Name","笑笑");

stringresultData=Post(dic,PostUrl);

（2）Post方法

#regionpost帶參數(shù)的請求

///summary

///指定Post地址使用Get方式獲取全部字符串

///Post是從服務(wù)器上傳送數(shù)據(jù)

////summary

///paramname="url"請求Url地址/param

///paramname="dic"拼接Url的字段/param

///returns/returns

publicstaticstringPost(stringurl,Dictionarystring,stringdic)
