為了方便打包給測試部的同學測試晌端，我們會把測試包上傳到蒲公英平臺，蒲公英平臺又提供了上傳apk的api恬砂，所以咧纠，可以直接在Android Studio里面上傳，寫個Gradle Task運行一下就行泻骤。

需要傳包的時候漆羔，點一下命令就好：

POST參數(shù)

接下來慈格，新建一個Gradle文件

import groovy.json.JsonSlurper

/**
 * 上傳apk到蒲公英
 */
def uploadApk() {
    //查找上傳的apk文件
    def apkDir = new File("build/outputs/apk/debug")
    if (!apkDir.exists()) {
        throw new RuntimeException("apk output path not exists!")
    }

    def apk = null
    for (int i = apkDir.listFiles().length - 1; i >= 0; i--) {
        File file = apkDir.listFiles()[i]
        if (file.name.endsWith(".apk")) {
            apk = file
            break
        }
    }
    if (apk == null) {
        throw new RuntimeException("apk file not exists!")
    }

    println "*************** start upload file ***************"

    def twoHyphens = "--"
    def boundary = "*********"
    def end = "\r\n"

    //模擬表單上傳 multipart/form-data
    def conn = new URL("https://www.pgyer.com/apiv2/app/upload").openConnection()
    conn.setRequestMethod('POST')
    conn.setRequestProperty("Connection", "Keep-Alive")
    conn.setRequestProperty("Charset", "UTF-8")
    conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary)
    conn.setDoInput(true)
    conn.setDoOutput(true)

    //添加參數(shù)：_api_key
    def sb = new StringBuilder()
    sb.append(twoHyphens).append(boundary).append(end)
    sb.append("Content-Disposition: form-data; name=_api_key")
    sb.append(end).append(end)
    sb.append("填自己的apikey").append(end)

    //添加參數(shù)：buildUpdateDescription 更新日志怠晴，取值git
    sb.append(twoHyphens).append(boundary).append(end)
    sb.append("Content-Disposition: form-data; name=buildUpdateDescription")
    sb.append(end).append(end)
    sb.append(getGitVersionInfo()).append(end)

    //添加參數(shù)：buildInstallType 設(shè)置密碼安裝
    sb.append(twoHyphens).append(boundary).append(end)
    sb.append("Content-Disposition: form-data; name=buildInstallType")
    sb.append(end).append(end)
    sb.append(2).append(end)

    //添加參數(shù)：buildPassword 設(shè)置密碼
    sb.append(twoHyphens).append(boundary).append(end)
    sb.append("Content-Disposition: form-data; name=buildPassword")
    sb.append(end).append(end)
    sb.append("1024").append(end)

    //添加參數(shù)file: 需要上傳的apk文件
    sb.append(twoHyphens).append(boundary).append(end)
    sb.append("Content-Disposition: form-data; name=file;filename=").append(apk.getName())
    sb.append(end).append(end)

    def dos = new DataOutputStream(conn.getOutputStream())
    dos.writeBytes(sb.toString())
    dos.flush()
    sb.delete(0, sb.length())

    def fis = new FileInputStream(apk)
    byte[] bf = new byte[8192]
    int len
    while ((len = fis.read(bf)) != -1) {
        dos.write(bf, 0, len)
    }
    sb.append(end)
    sb.append(twoHyphens).append(boundary).append(end)
    dos.writeBytes(sb.toString())

    dos.flush()
    fis.close()
    dos.close()
    conn.connect()

    def text = conn.getContent().text
    def resp = new JsonSlurper().parseText(text)

    println text
    println "*************** upload finish ***************"

    if (resp.code != 0) {
        throw new RuntimeException(resp.message)
    }

    //瀏覽器中打開短連接
    def url = "https://www.pgyer.com/" + resp.data.buildShortcutUrl
    print("上傳成功，應用鏈接：" + url)

}


def getGitVersionInfo() {
    return 'git log -n 1'.execute().text.trim()
}

//打包測試環(huán)境apk 上傳蒲公英 發(fā)送郵件功能使用蒲公英自帶的郵件功能
task uploadApk(group: "upload") {
    dependsOn("assembleDebug")

    doLast {
        uploadApk()
    }
}

然后浴捆，把這個文件丟到根目錄蒜田，再在app的build里面引用一下就行。

apply plugin: 'com.android.application'

apply from: "../uploadApk.gradle"

注意地方：
1选泻、上傳目錄需要根據(jù)自己的情況來修改
2冲粤、得填上自己的key
3、可以按需根據(jù)api文檔傳不同的值來設(shè)置上傳參數(shù)（密碼安裝等）
